Hello,

On Linux (Ubuntu), I encountered a problem with the serial console printing garbage characters on the Nano20k. The issue was resolved the latest BL616 firmware (2025012315). I have another Primer 20k board experiencing same problem. Could you please provide an updated firmware for the Primer20k?

Thank you.

If anyone is intrested to flash this firmware using Linux, there is repo https://github.com/bouffalolab/bouffalo_sdk available.
Clone repo and go to tools/bflb_tools/bouffalo_flash_cube.
Run command line tool (of course you need to edit chipname for different model and file name):
./BLFlashCommand-ubuntu --chipname bl616 --flash --write --file bl616_fpga_partner_NeoDock.bin
