the self built bl602_boot2 is very different from pre-built one - pinecheng - 09-16-2025
Anyone is still playing PineCone? I am trying to build blsp_boot2 myself using the bl_iot_sdk tree.
However, the binary that I built is very different from the prebuilt image bl_iot_sdk/tools/flash_tool/bl602/builtin_imgs/blsp_boot2.elf
Here is how I did:
$ cd bl_iot_sdk
$ export BL60X_SDK_PATH=$(pwd)
$ export CONFIG_CHIP_NAME=BL602
$ cd bl_iot_sdk/customer_app/bl602_boot2
$make
The generated binary bl602_boot2.elf contains the main function like a dummy.
230002aa <main>:
230002aa: 8082 ret
230002ac: 0001 nop
230002ae: 0101 addi sp,sp,0
The pre-built blsp_boot2.elf seems to be a valid one, which matches the bl602_boot2 code.
Can anyone point out what I have missed here? thanks so much in advance.

I once again checked where the main function comes from from my build log. The libraries: libbl602_boot2.a, libbl602.a, andlibbl602_std.a are the products of components that bootloader depends on. And the "main" seems to come from the libbl602_std.a (bl602_mfg_flash.c) instead of libbl602_boot2.a (blsp_boot2.c).
So the question now is what is the correct way to build the bootloader blsp_boot2?
thanks
