Ox64 Notes by TL Lim

UPDATE 2 Nov 2023: Check out the article...

• "Ox64 BL808 RISC-V SBC: Booting Linux and (maybe) Apache NuttX RTOS"

The First Batch of Ox64 (Oct 2022) won't appear as a USB Serial Port when connected to our computer because...

"The bin file that currently loaded in Ox64 still initialize and not response to UART or USB, however, it will setup the BL808 internal PMU and this is how product team aware that Ox64 board is working. This is the bl808_demo_event.bin file attached here.

• bl808_demo_event.bin

"For UART output log file, you can try to flash whole_flash_data.bin file attached here."

• whole_flash_data.bin

"I also attached the guide on using BL808 programmer utility "BouffaloLabDevCube-v1.8.0" software."

@elektro-NIK how to I get my chil to show up as a serial device?

@dakhnod do you mean board must emulate serial device trough USB-C port?
I don't try it yet, but you may use USB ACM example in SDK to do it: https://github.com/bouffalolab/bl_mcu_sdk/tree/master/examples/peripherals/usbdev/usbd_cdc_acm

@elektro-NIK AFAIK if you start che MCU in bootloader mode it should pop up as USB, if you believe the datasheet. That is the mode I am trying to reach

@dakhnod I think it may be disabled by efuse, but it's only guess.

Hey, I am getting the error "ErrorCode: 003D, ErrorMsg: BFLB FLASH MATCH TYPE FAIL" it'd be great if anyone could help me figure out what's wrong. I am able to get the handshake and chip ID but unable to get the JEDEC ID it always shows up as 00000000 and that is leading to this problem.
Also, I am using Dev Cube version 1.8.3

@dchokola The software can be downloaded from here - https://dev.bouffalolab.com/download
