Hi, I've just picked up couple of temperature-humidity sensors from aliexpress. This time they on BL602 soc.
I've went through this topic and some others but still facing issues that I can't resolve. One of the first bumps I've hit was board pin labels. They are hidden on the back side of the board. RX and TX is swapped around. You have to connect your UART programmer RX to RX and TX to TX (maybe its just manufacturer specific, idk). I was unable to flash OpenBL602_1.18.37.bin using BouffaloLabDevCube-v1.9.0 settings presented in other topics. Every time I've selected ./chips/bl602/partition/partition_cfg_2M.toml I was hitted with "ErrorMsg: BFLB FLASH SIZE OVER FLOW", here is some more of the output:
So I've went for smaller size (not sure if that is the way to go), but figured since firmware is ~786,5 kB it should fit. This how my settings look like:
As you can see I'm using shipped with BouffaloLabDevCube startup, configuration and bootloader files. I've tried different combinations, including those from OpenBL602 repo - without any luck if i use 2M partition table.
This is final part of the output when flashing with 1M partition table:
Board boots, it drains only 9-10mA and debug output looks as follows:
Unfortunatelly can't find device AP over the Wifi.
Any help would be appreciated.
Thank you.
