Alright folks! After reading through this entire thread a few times It seems we should all know by now how to
a) change the name (this is super easy)
b) change the tones (startup beeps, I have yet to attempt this, but with the advice from BuriedCode we should be able to)
c) change any other settings in the Config tool


Now my question is, has anyone successfully been able to alter the internal EQ of the CSR8635? I have been struggling to do this (I am using the Universal Parameter Manager (UniversalFrontEnd.exe) obtained from a buddy in China helpin me with this.

However I am having difficulty connecting to this program as "algorithm not recognisible" keeps showing up. My guess is I would need to alter a setting inside PSTools or Config Tool to allow connections to the Parameter Manager?

If anyone is currently experimenting with this and has any insights, please let me know. Maybe there is a way to edit the EQ within PSTools or the Config Tool however I have searched diligently and been unable to find any.

Also if anyone can put in directions of how to unbrick a module please let me know. I have two bricked modules with the "correct" code saved as a dump however this backup file is not doing anything for me. Cannot seem to load it properly. Maybe im missing some step?

I open PSTools
I connect to the USb SPI (takes forever on the bricked modules)
File-merge
select dump
and done.

Usually ends with error with bluetooth address or something. Or also PSTools will crash will trying to connect to the SPI.

Hi,
I have the same problem with the CSR8645 (F-3188 module). My module stopped working as a result of upload config from Config Tool CSR8600 ROM series. I've made a backup (PS Tools , Headset) but have no idea how to use it (communication seems not work).
Bluetoothnewbie - how long it takes PSTools to connect to your bricked module ? (secconds, minutes ...)
Please, any advice how to restore to life this module.

I´m also curious to see if we can change the EQ of these modules.
As for PS tools, I´ve manage to change Name, Fixed volume tomes, Tones, Button presses. The only thing i´m missing is to change the TX power for longer range. I´ve never used PS-Tools to merge, heard too many people messing it up. So I´m using the command prompt with the useful commands described on https://github.com/lorf/csr-spi-ftdi to merge. Never had a failure unless i messed up when editing in Notepad++

If you could be so nice and share the UniversalFrontEnd.exe, I´ll be happy to share any progress that I´ll make :-)

The 8635 configures itself when it boots by reading default parameters, called Keys from ROM. It can be customised by writing modified parameters into EEPROM which then mask and overide the corresponding default parameter. These modified parameters are called persistant store keys (PSKey). PSKeys are split into three groups. The first are fully locked down from manufacture, they configure the bluetooth radio and other regulated features. The second group contain the user configurable PSKeys; those from 0 to 24 are secure keys and need the CSR86xx Series ROM Configuration Tool to write to them. The keys from 25 to 49 can be written to using the PSTool.

The event tone parameters are stored in PSKey USR26. The format is four hex digits:
xxyy xxyy, where xx is the event and yy the tone to play. Setting all the yy digits to 00 removes the tones.

The Hands Free Profile is stored in USR3 and can be removed by simply deleting all between USR3 up to USR4. Alternatively the ROM Config Tool can be used to unselect the HSP and HFP profiles under the HFP tab.

Finally to change the module name from SanwuAudio use the PSTool, search for name, type in the new name and press Set.

 


Hi there Fixedcoil,

I have also been working on reprogramming the CSR Module.

I have noticed that as mentioned in this thread disabling the VM greatly reduces the issues.

I have successfully updated the Name to my own liking, but I am unable to remove the event tones.

When I download a dump from PStool or Rom config there is no values in USR26.

from PSTool:

At this point I am not sure how to remove the sounds that occur on boot up or during volume changes.

I too would enjoy a permanent EQ adjustment.

Please let me know if any one has any thoughts.

Thanks Tristan

Hi Tristan, to get the module to work you have to do some changes. If you pay attention there are missing some part in the edited code.
Example, "//USR 25 - PSKEY_EVENTS_C"  Yo have to edit it to: "// PSKEY_USR25" it´s important to copy it exact, all the spaces underscore etc. Remove the  "- PSKEY_EVENTS_C " part at the end of the edited code too.

I´ve not had any problem changing tones etc with this metode. Perhaps you can keep the "- PSKEY_EVENTS_C " but I don´t  take any chances :)

Hi guys.

I got dump (PStool backup), i wrote into file (Config tool backup), compared.
I tried to 'marge' it in PStool or/and 'Write ti device' in Config tool. Programs says - successful.
But if i 'Open from device' in Config tool there is still old settings (I did also factory restore all in PStool)

Does anyone know how to write new settings (PStool or Confing tool) please ?

Thanks a lot.

I haven't been able to 'write to device' using the 'config tool' without bricking the module. PStool uses the 'merge' to write new settings, but as I've stated many times in the thread, I have only been able to do this manually by adding/modifying the PSkeys in notepad.

Configuring CSR86xx is a big challenge. A very important thing is to make a good backup. The best solution I've found so far is to use the application BlueModify from http://www.cisdo.cn/post/5.html (Chinese production tool, to make it working you need replace driver USBSPI.dll).
Backup made by PSTool and / or Config Tool does not allow surely restore the initial state in case of problems. It is necessary to take a direct copy of the external EEPROM (sometimes Flash). This can be done using e2cmd from Bluesuite package, but much better option is Bluemodify. I'm writing this post because I spent a lot of time to restore my module to working condition.

One of the two modules I have (CSR8645, F-3188) goes sleep after about 300s.
Do you know how wake CSR8645 from sleep? How to turn off "deep sleep mode" ? Do you have any experience ?
It does not help to disconnect power.
The only thing that helps is to wait a few hours without power :)

anyone know the pitch of the spi lands on the tda7492p?  I'm waiting on my board to arrive, but from beercohol's previous post it looks to be 1.27mm. I'd rather try attaching a header rather than soldering to those tiny pads. My hands aren't so steady anymore. Thanks.

Hey there,

I've also managed to trash one of my CSR8645 modules (My own fault, I should've read about the config tool bricking modules). I see I can still sort of read/write the EEPROM, is it possible that anyone would be able to send me a copy of the ?  I gather its 128kbits based on what e2cmd and friends tells me.

I've bought CSR8630 based module. It is advertised as AVRCP 1.4 Compatibile, but I did not find any way to extract AVRCP metadata (which is a part of 1.4 spec). I've managed to dump and write config using 86XX config tool. If anyone knows anything about a possiblity of gettin the metadata using this module, please let me know :) (Otherwise I will have to purchese PI Zero W :) )

I believe you can change the value of the timeout using the 'CSR8600 ROM series configuration tool' under the tab 'timers'.  You can also change how it behaves in terms of power saving, sleep, and what to do when it loses connection.  There's a wealth of config settings.

I think I have posted this here before, if not here it is (apologies to admin if this isn't legit, I haven't seen licensing mentioned anywhere so I'm assuming this is free):

http://www.tinyosshop.com/download/CSRXX_ROM_ConfigTool_3.0.64.rar

Please note, as I've mentioned ten times before - only write to PSR file, never 'write to device'.  As this app will only output a handful of PSkeys.  'Open from device', make your changes, save to PSkey file, then check the values in the generated file against a full 'dump' file.  You will see that a couple of hex values have been changed if you have made changes in the GUI.

As far as I am aware, the 8645/0630 are ROM devices, so their ROM mask determines their capability, whilst the EEPROM determines the configuration of its functions.  Unless the UART is enabled I don't think there is any way to access metadata with these modules.  It could be that the CSR8630 modules floating about do have their UART enabled, but I have yet to see a 8645 with it.

You might be better off using a more expensive module like the RN42 http://www.microchip.com/wwwproducts/en/RN42 or perhaps other microchip modules: http://www.microchip.com/ParamChartSearch/Chart.aspx?branchID=12094

Often these will have teh UART interface enabled and allow for AT commands that may, or may not.. allow you to access the metadata.

Very useful post, especially for EQ programming lipton5001 !!
I plan to build an adaptative BT APT-X receiver..
{(Pink noise & Dirac generator + measurement microphone + Spectrum analyser -> EQ curves and compression (with delay ?)) => CSRA Flash}

I bought a CSRA64215  module (stamp) on ICstation webstore  (hope it is compatible and writeable, not received yet), looking forward to try this !
(http://www.icstation.com/btm625csra64215-bluetooth-audio-module-wireless-module-i2stwsaptx-p-9959.html)

Have you drawn a schematic on how to connect to the USB-SPI dongle ?
Any suggestion on where to buy this dongle and the motherboard for the stamp ?

Thanks again, it was very hard to find someone who managed to use EQ (is the compressor-expander as trivial ?) on this chip, and explained it

Thx, thx, thx.  :-+

First off thanks a lot for all the research that has already been done in this thread and elsewhere. I read through it all and tried to understand as much as I could and I think I got the software part of the config changes pretty well figured out.

But what ultimately holds me up at the moment is the hardware part of hooking up the programmer to the CSR8635. I bought the FT232RL FTDI programmer as suggested by the Readme in the csr-spi-ftdi repository. Could someone advise me how I should connect the FT232RL to the CSR8635 based on these pictures (http://imgur.com/a/Rj9qN)? I marked the traces that connect the test points on the board with the CSR8635 using photoshop.

Thanks a lot for any help it is extremely appreciated as I'm really stuck here...

Kind Regards
Marc

The good news is you already have the hardware you need.  The bad news is, that particular FT232R board only breaks out the most common connections (*most* applications only require Tx, Rx and a couple of handshaking lines). 

Here are the connections:
https://github.com/lorf/csr-spi-ftdi#using-ft232rl-breakout-board-as-a-programmer

It seems you either have to get a FT232R breakout board with all the connections - I soldered a chip to a generic SSOP28 breakout board, or if you have a steady hand and some kynar wire, solder wires directly to the chips pins.

I haven't used the CSR8635, but that small carrier board on your main board looks to be a BTM835.  As shown here:
https://www.eevblog.com/forum/projects/programming-off-the-shelf-csr8635-module/  (scroll down for pinout).

From that image in imgur - with the help of your red lines showing connections, and *if* it is a BTM835, then the pins appear to be (from left to right):

GND
MOSI - Master out, slave in... RI on FT232
CLK - clock, RTS on FT232
CS  - chip select, DTR on FT232
MISO - master in, slave out, DSR on FT232
SPI_PCM - should be pulled high to IO voltage via a ~10k resistor.  IO voltage will be 1.8V


the 1.8V is available on that module on pin 10, and should be the input to VCCIO on the FT232.   But I have used it with 3.3V IO voltage, and as long as you have series resistors for every connection (I used 220ohm) I'm sure it'll be fine.  That FT232R module looks like it has switchable IO voltage 5V/3.3V, you'll want to use 3.3V.

Its a bit of a pain, I was fortunate enough to have a breakout board and spare FT232R's left over from projects.

Thank you very much Buriedcode for your answer. I'm currently looking around for a breakout that includes all connections. Should this have all the needed pins broken out?

I checked the ebay listing from the amplifier and it says that the carrier board is in fact a BTM836 but after a quick search on google it seems that such a board doesn't really exist so I'm not sure what to make of it. Here's the ebay listing of the amplifier board:

Thanks a lot for the clarification on the 1.8v 3.3v difference. I was really hesitant because I thought I would fry the chip for sure with my 3.3 volts.

Thank you very much Buriedcode for your answer. I'm currently looking around for a breakout that includes all connections. Should this have all the needed pins broken out?

Looks fine.

I based my assumption off the chip used (CSR8635) and how it looks (some boards have the chip horizontally - square, others have it diagonal like that).  I would bet it is the BTM835 if the main chip on there is indeed a CSR 8635.  I haven't heard of a 8636.  The fact the amplifier board broke out those pins to a header implies it really is for configuration, in which case I do think the pinout is correct.

Yeah, I originally just used the 1.8V pin to provide the VCCIO voltage for the FT232, but I made a mistake hooking it up and ended up using 3.3V (again, with every data connection via 220ohm resistor).  I didn't fry anything but.. the real problem is the MISO line - that is the data coming from the bluetooth module, which will be at 1.8V level.  1.8V TTL logic levels aren't really compatible with 3.3V, I'm surprised it worked at all. 

Edit: Apparently the FT232R has CMOS inputs - the input has a threshold with hysteresis rather than specific high/low thresholds like TTL.  This means as long as the device can output >1.2V for a logic high, it'll work.

Everything went just as planned, changed the bluetooth name and lowered the output gains. Seemed to write fine and the module works after a restart, bluetooth name successfully changed. Couldn't test the new gain settings yet. Big thanks to Buriedcode for helping me out here and all the other lovely people in this thread.

One more thing to make this module perfect: Has someone figured out how to change the default volume level? Because at the moment it's way too high and if I change the volume over bluetooth before playing music it gets reset to the default level when I start the playback.

I believe the 'CSR8600 ROM series configuration tool' has a default volume level on its first page.  Off the top of my head, i think its under the 'features tab' on the right, 0-15.  Theres also a checkbox to make all feedback tones the same volume, and you can set that too (handy to make them quieter).

I understand that I need to connect in this way ? (on picture)
