[Question] How to program low_load d0/m0 by command line?

[cjacker]

whole image can be programmed by 'bflb-iot-tool' by:

bflb-iot-tool --chipname bl808 --interface uart --port /dev/ttyUSB1 --baudrate 2000000 --firmware whole_img_linux@0xD2000.bin --addr 0xD2000 --single

Update : To program low_load firmwares, bf-mcu-tool need to be patched as : bouffalolab/bouffalo_sdk#115 (comment)

[Question 1] How to program low_load by command line?

From the log of BLDevCube,

• bootinfo_group0.bin programmed to 0x0000
• bootinfo_group1.bin programmed to 0x1000
• low_load_bl808_m0@0x58000000.bin programmed to 0x2000
• low_load_bl808_d0@0x58000000.bin programmed to 0x52000

It seems latest 'bflb-mcu-tool' do not support groups and generate 'bootinfo_group0.bin' and 'bootinfo_group1.bin', also can not program 2 firmwares in one time.

bflb-mcu-tool didn't work for me even with those patches, so I threw this together: https://github.com/Pavlos1/bl808-utils
