I am trtying to keep my pcduino 3 nano alive. It has been working perfectly under a debian bullseye distro from Johan Gunarsson for 4 years and now I can't get the OTG to work under any release (bullseye, bookworm or trixie) I have explored many avenues, but even a plain manual setup of g_mass_storage doesn't work in a workable way. The drive appears in Windows Explorer after several minutes, and any copy or delete to that gadget drive takes ages (3+ minutes for a 12kb file) before it fails or succeeds silently. I am looking for a forum where pcduino users can help each other. Thank you, Gaetano.

@shexplorer Control +c should have worked after: U-Boot SPL board init U-Boot SPL 2017.09_armbian-2017.09-S93fe-Pe5fd-Hbdb5-Va5b2-Bbf55-R448a (Nov 06 2025 - 16:35:49) SPL Hotkey: ctrl+c Make sure that USB TX is well connected to RX and try to spam it. Or use another terminal emulator, like putty instead of screen on a bash terminal. Maybe control is being intercepted.

Hi, first of all thank you for your support. Unfortunately, I could not get it to work. I just don't want to boot anything I store on the SD card. Also, the CTRL+C method won't work. I have to reset the board manually after every try and when powering on while holding CTRL+C the only thing I see in the console is "SPL Hotkey: ctrl+c" as additional line. Maybe the only option is to get into Mask Mode and flash the emmc over USB. But the onboard button won't work to enable it at boot. Maybe I can short some pads but without labeling I dont know which. I attached some output logs and photos of the board. boot_with_armbian_sd_insert.log boot_with_ctrl_c.txt boot_without_sd_insert.log

@Harleyyyu my 2 cents thought ..... We are talking about a 10 dollars soc . Is already a great milestone it is " just working" Anyway.. If you achieve any good result let's us know

For now i just went back to 6.6.22 version and ill focus on applying ffmpeg patches instead to openauto. Not gonna lie, it was fun seeing even just a small result from trying to build a kernel with hantro vpu working.
