Hello,
I’m trying to create a simple program to test BLE functionality of my board. The board does not have HSE but it has LSE. I'm not sure if that is a problem. I'm using PlatformIO for the programming, configurations and building/flashing.
When I upload the program to board it goes to infinite loop on
if (!BLE.begin()) {
while (1);
}
more specific on
__WEAK void shci_cmd_resp_wait(uint32_t timeout)
{
for (unsigned long start = millis(); (millis() - start) < timeout;)
{
if (CmdRspStatusFlag == SHCI_TL_CMD_RESP_RELEASE) // <---- looping here
{
break;
}
}
return;
}
This could be result of multiple reasons. Some things I have tested are:
1. Use STM32CubeProgrammer to flash
stm32wb5x_FUS_fw.bin to address 0x080EC000
stm32wb5x_BLE_HCILayer_fw.bin to address 0x080E0000
and set application code target address to 0x08000000
as per release notes
CubeProgrammer is able to read FUS infos and also start wireless stack
2. Generate linker script with STM32CubeIDE and use it
3. Optimize platformio.ini to include and exclude certain stacks
4. Configure my custom board
5. Set clock configurations in variant_SAVI.cpp
6. Set BLE specific setting in app_conf_custom.h
However it always still seems to get stuck in the same loop even I update settings or code.
I would be really grateful if someone is able to point out the problem, be it hardware or software related.
