Phy_802_15_4_Cli commands not working as expected on custom board

[MSatt.4]

I cannot get the Phy_802_15_4_Cli example project working on our custom board (as part of certification). Seems like there is something wrong with the CM0 / CPU2 core, but I have no idea what the return codes mean.

Only things I have changed in the example project are:

• UART parameters
  • Using LPUART1 as CLI interface instead
  • Enabled the relevant clocks
• CFG_DEBUG_TRACE = 0
• CFG_FULL_LOW_POWER = 0
• CFG_LPM_SUPPORTED = 0
• CFG_LED_SUPPORTED = 0
• CFG_BUTTON_SUPPORTED = 0
• Changed the various GPIO pin mappings
  • GPIO_TX_PIN
  • GPIO_HARD_FAULT_PIN
  • GPIO_MCO_PIN

I need to get this to work with CubeMonitorRF, but it is also running into the same issues.

 Could someone please help me out and get this working properly? Thanks.

There is more info available through the traces output...

ip802154_lld_radioInit() FAILED  1 : 0x62
ip802154_lld_init() FAILED  4 : 0x62

I used the debugger to inspect this as I cannot attach the UART on this board easily.

This happens before any commands are sent in the CLI.

Well woke up this morning and reflashed everything just to try and... it's working :face_with_steam_from_nose:

I think the "Start wireless stack" was the cause of it, but I definitely did this yesterday... maybe something went wrong unnoticed.
