Hantek HDG2002B AWG: 5Mhz or 100MHz? Let's see!

<< < (38/134) > >>

rdg:
Hi all,

I just received my new HDG2002B. It seems to work fine except for a couple of bugs that nobody else seems to have mentioned.

The most annoying is that the jog dial seems to be working backwards. Rotating clockwise decreases the value or moves the selection to the left.
Another is that on bootup the buzzer emits a high pitched sound until it beeps on a key press and then the sound goes away.

The unit is reporting software version 1.0.1.1, kernel 3.2.35, FPGA 10, PCB ? ? ?. I would be happy to send firmware dumps if it is useful to anyone.

@rdg: I don't think "the beep until you press a key" is normal and for me, the jog wheel is set to increase values when turned clockwise, decrease when turned counter clockwise. I think you may have an issue with your input/keypad board.

That is strange. It seems you have a new software version and an old FPGA version...
The last software version was 1.00.2(140422.0)  with FPGA version 12 reported by IanJ and Dago... it would be quite logical to see a 1.00.3 new version...Could you tell us the date of your version and also could you post it, at least /afg_bin and the drivers?

Just in case hereafter a procedure which won't modify the file attributes:
if you insert a SD:
tar -cvf /mnt/sd/driver /dso/driver
tar -cvf /mnt/sd/afg_bin /afg_bin

or if you connect a usb stick
tar -cvf /mnt/udisk/driver /dso/driver
tar -cvf /mnt/udisk/afg_bin /afg_bin

You could then zip and post the 2 files on your media (driver and afg_bin).
As we already have 2 versions available, you may be able to downgrade to one of them.

IanJ or Dago (or someone having v1.00.2) could you please post your afg_bin and drivers as well ? At the moment I only have V1.00.1. Thanks!  :)

Standard SMD0603 / 50V will do ;)

AH HA!  And there is MORE!  If I am a good little boy and follow the nice machine's instructions, I get THIS!:


--- Code: ---#####    Boot for SKY2416/TQ2416 Main Menu      #####
#####     EmbedSky USB download mode     #####

[1] Download u-boot or STEPLDR.nb1 or other bootloader to Nand Flash
[2] Download Eboot (eboot.nb0) to Nand Flash
[3] Download Linux Kernel (zImage.bin) to Nand Flash
[4] Download LOGO Picture (logo.bin) to Nand  Flash
[5] Download UBIFS image (root.ubi) to Nand Flash
[6] Download YAFFS image (root.bin) to Nand Flash
[7] Download Program to SDRAM and Run it
[8] Boot the system
[9] Format the Nand Flash
[0] Set the boot parameters
[a] Download User Program
[n] Enter TFTP download mode menu
[r] Reboot u-boot
[t] Test Linux Image (zImage)
Enter your selection:

--- End code ---

 8)  Cool.  The two are not related of course, because you get the same "hold Space to download" prompt even without the SD card in the front.

Yes you can boot from SD. What you saw is uboot, the bootloader. This is the first program which is loaded in memory. During normal startup, it loads the kernel and linux. If you stop it before with space key, then you are able to update your board, either via a SD or the network. Be careful when using uboot as you could easily brick your board when doing mistakes.
SD Boot is a very convenient feature as if you screw your nand, then you can boot on a SD (you just need to put a bootloader on it). It is also a convenient way for updating your software: the bootloader on the SD will automatically flash your nand with the new software on the SD.
You could also boot completely your system on the SD.
In our case, booting from a SD would allow, for example, to backup the system and hack it automatically without opening it, or it could for example also allow to boot with a terminal on the HDG screen so you would only have to plug a USB keyboard in the front USB jack to play with the system.
When I have more time, I will do it.
