BL808 running problem #63

Open elektro-NIK opened 1 year ago

elektro-NIK commented 1 year ago

Hello! I have a Pine64's Ox64 board (with 2MB flash) and I don't run helloworld app.

I have:

bl_mcu_sdk master branch
riscv64-unknown-elf-gcc (Xuantie-900 elf newlib gcc Toolchain V2.6.1 B-20220906) 10.2.0
bflb-mcu-tool 1.8.1

What I do:

clone bl_mcu_sdk
copy bsp/board/bl808bk to bsp/board/Ox64
change xip_memory LENGTH from 32M to 2M in both linker scripts
enter into examples/helloworld
make CHIP=bl808 CPU_ID=m0 BOARD=Ox64
bflb-mcu-tool --chipname=bl808 --port=/dev/ttyUSB0 --baudrate=2000000 --firmware build/build_out/helloworld_bl808_m0.bin
flash writing and verifying success
after reboot board I have not any messages in serial monitor (GPIO14/15 2000000 baud)

I don't have JTAG adapter for debug MCU startup yet. Maybe I make some stupid mistake and someone shows me this?

Hi @elektro-NIK , this is due Flash memory misconfiguration.

Try this: https://github.com/bouffalolab/bl_mcu_sdk/issues/32#issuecomment-1345646038

@gamelaster I try your instruction, but my board still not work.

cat $HOME/.local/lib/python3.10/site-packages/bflb_mcu_tool/utils/flash/bl808/flashcfg_list.csv | grep ef6015

ef6015,W25Q64JW_ef6017.conf

cat $HOME/.local/lib/python3.10/site-packages/bflb_mcu_tool/chips/bl808/eflash_loader/eflash_loader_cfg.ini | grep -A 4 FLASH_CFG

[FLASH_CFG] flash_id = ef6015

bit 7-4 flash_clock_type: 0:120M wifipll, 1:xtal, 2:128M cpupll, 3:80M wifipll, 4:bclk, 5:96M wifipll

bit 3-0 flash_clock_div

flash_clock_cfg = 0x43

I see on Pine64 wiki page are wrong datasheets for flash chips: GigaDevice instead of Winbond on the board. I will try to edit this page.

Hmm, that's weird. Can you please take a picture of SPI Flash chip? Thanks

I have managed to compile and flash the Hello World example on the 16MB version but it didn't work on the 2MB version. Do you have the 16MB version available to test that one?

elektro-NIK commented 1 year ago

Yep, I have the same behavior. All works on 16MB and not works on 2MB board.

gamelaster commented 1 year ago

I'm working on it. It is 100% issue with flash configuration, because BootROM can both read and write to SPI Flash. Only when the firmware is executed, the special configuration is used to use higher speed clocks and flash related modes to have higher transfer speeds, and this is not properly configured, so flash don't work at all.
