Programming Problem with my own SoloKey

[0xanik]

Hi,
I made my own solokey nano hardware exactly from the schematic and BOM, at the first plug DFU mode is available, according to the documentation I flashed the official bundle-hacker-4.0.0.hex and then:

$ solo program aux leave-dfu
Rewriting option bytes...
Warning: OSError with write_page
Please powercycle the device (pull out, plug in again)

I did powercycle but nothing happened! no detection, no log, no led blink...
seems solo key is broken! I revive it by full erase and nswboot = 1 with jtag and stm32cube tool.

• I saw issue Solokey hacker not turning on after solo program aux leave-dfu (Warning: OSError with write_page) #206
• I did flash my local build, or only bootloader and other scenarios

Best Regards.

Did you use solo for the actual DFU mode programming, too? If so, can you check solokeys/solo1-cli#98?

Hi guys, I have the same problem. The thing is LED is working but there is no USB activity. I am a little bit old school So I use STM32CubeProgrammer to directly write bundle-hacker-4.0.0.hex and change the Option Bytes.
Some other notes:

• Hardware works fine, I have tried to program and run various tests and it works fine.

• LED blinks and work (So the bootloader works)

• USB works fine cause I have successfully program and verified over DFU using STM32CubeProgrammer.

-The thing is I can not enter DFU using pushing button,

Any suggestion? Is there any way to read the debug log?
