Hello,
I have a TL866Cs modified to A version. I rencently made successfuly upgrade to v6.82 using Radioman procedure (BTW thanks Radioman for the great job). The programmer is working very well, but I have observed that I get a GND #25 error in the programmer self test, evne if it does not affect the functionality of the programmer.

Is somebody observing the same behaviour ?

Any idea or comment about this ?

Thanks
Hi! you have a short in the GND20 signal affecting the Pin 20 on the ZIF socket and probably this is why you don't have any error yet.
You must check the Q7 transistor and the R26 resistor like in the atached image.

Hi Radioman,

Thanks a lot for your help and wise analysis. I now understand that I probably made short on the R26 resistor during the connection of the 100 Ohms resistor to enter the boot mode.

You are of great help.
Thanks again

Yes, this is the most common mistake! Use A magnifying glass and check for solder joints or solder execess that can make shorts between the PCB traces.

Hi,

R26 changed. Self test working now perfectly.

Thanks again

Hi,
Many props to radioman and everyone else for making this possible.
I attempted to upgrade my tl866CS using the old 2.2 updater without reading the later pages :palm:.  When i ran the minipro software it tells me that i have a pirate device and can no longer program anything as it only will see an id of 0x 02 00 55 even when nothing is in the socket.

Looks like i may have botched it.

I've built the LPT ICSP programmer and attempted to flash a hex file created by the 2.4 firmware updater but it does not seem to program.  I've checked all the solder connections are OK and that the settings mentioned in the pdf for picPGM are good but i seem to have managed to proper brick it.
Does anyone know anything i can try to get it back on it's feet?
I don't really want to have to buy another one if i can help it especially with the hostility the developer has.

OK, i managed to figure out why it was not working.  Turns out i forgot to re-enable the code protection bit when flashing the firmware  :-DD

In the end i re-read the instruction PDF and used the bootloader resistor and re-flashed it back to CS firmware then flashed it to the A firmware with the 2.4 updater.

tl;dr - don't take the ikea furniture instructions approach when doing this mod.

Indeed. Glad you got it working. :-+

@radioman

If we may know...
What are the changes in the TL866 firmware updater V2.5 ?

Not so many changes. Just an improved algorithm for encryption and serial code generation.

thanks a mil radioman for all your hard work, really appreciated!
I had an original CS version that converted to A some time ago and now I get the "converted message" and when I try to read some brand new W28C512 eeproms I get an ID error - if I disable ID check then it starts "reading" but all it does is repeating a string periodically that consists of my device and serial numbers plus some giberish after that  :palm:
I had no idea this bricking was a thing and today I updated to 6.82.

I guess the manufacturer thought if he starts bricking programmers then most customers will buy the II version or something  |O

Before I do anything stupid, v2.5 of your software gives me this:



I checked the displayed device/serial numbers and they are my original ones - I saved them before I did the A conversion.
So just to be sure, I follow your guide here: http://www.eevblog.com/forum/blog/eevblog-411-minipro-tl866-universal-programmer-review/msg1704092/#msg1704092 right? There is no other way to fix only the checksum correct?
I also need to do the bootloader mod, it is disabled on my programmer.

I had exactly the same mistake (Bad serial checksum), it was my mistake during upgrade.
I've fixed this picprog3 to upload full flash. I think you can use the 100 ohm resistor described by Radioman if you do not have a pic programmer.

took 4 reflash tries to succeed but all is good now. Thanks again for all the help and to radioman for the hard work!

I also plan to buy the II version so I don't move the programmer around - dev weirdness aside this was really useful to my projects. I also have the gq-3x programmer but there is no comparison at that price point, TL stuff is just better. I know I know feeding the weird behavior but is there any other descent alternative?

What Windows programming software should be used with a working TL866CS?  Or does it even matter?  I saw in an earlier message that http://picpgm.picprojects.net/download/winpicpgm_v1650.zip was used but assumed that was just to program the PIC in the TL866 rather than a general programming package for the TL866 and its many various type and manufacture microprocessors.

I have never used my TL866CS since I bought it 2 years ago.  I assume it is a clone.  I bought it to program a Rensas R8C/27 but was not sure it would even do it since I did not see the R8 series in the list.

Thank you.

The official software for the TL866CS/A is the Minipro. Available for download at their official website Autoelectric.cn

Alternatively here is the link to the software http://autoelectric.cn/MiniPro/minipro_setup682.rar

By far this is the best programmer I have ever used for the past 6 years.
