JTAG IMPOSSIBLE TO FLASH DMA

Hello,

I purchased a DMA 35T (CH347) card from David, and I’ve encountered a few issues.

The first problem is that the card only powers on when the JTAG is connected. When I plug it into the "data" port, there is no light, and only the white LED lights up when JTAG is plugged in. I’ve already checked a few things:

The kill switch is correctly set.

The FTDI and CH347 drivers are installed.

I’ve tried different USB ports, but the issue persists.

I’ve tested various flashing tools, but I keep encountering the same issue.

Here is the error message I get when trying to program:

vbnet
Copier
Modifier
xc7_program
jtagspi_program
Info : clock speed 10000 kHz
Error: JTAG scan chain interrogation failed: all zeroes
Error: Check JTAG interface, timings, target power, etc.
Error: Trying to use configured scan chain anyway...
Error: xc7.tap: IR capture error; saw 0x00 not 0x01
Warn : Bypassing JTAG setup events due to errors
Error: couldn't stat() C:/Users/qcliv/Desktop/2.: No such file or directory
failed loading file C:/Users/qcliv/Desktop/2. to pld device 0
Info : Close the CH347.
If you have any suggestions or troubleshooting steps, I would really appreciate your help, as I haven’t been able to resolve the issue after several attempts.

Thank you in advance for your assistance.

Best regards,

tbh seem like a firmware issue. Purchase a new good 1:1 firmware never try to escape with a cheap option.

use other versions of the tool to flash the fw

Thank you for your reply. I bought a new DMA card and am waiting to receive it. I paid for it at Cyber ​​Ammo.

I'm almost 100% sure that the problem is with my card after doing as many tests as possible.

I tested it on different computers with different flash tools, as well as two different firmwares. Unless the problem is with the main computer, which I don't think so either after going through the entire computer, I conclude that the card is definitely defective.
