USAGE FAULT during broadcast change NRF5340 AUDIO DK

[uzer123]

I use the example with 2 gateways in BIS mode with NRF5340 AUDIO DKs.

Many times but not always, when i try to change from one gateway to the other with button 5 i get USAGE FAULT error. This is what VCOM shows:

Any solution or cause of this?

Hi, 

If you convert the decimal numbers to hex, specifically the contents of LR and PC, you should be able to do a lookup of the addresses using arm-none-eabi-addr2line:

arm-none-eabi-addr2line -e my-build-folder\zephyr\zephyr.elf 0x18a7f

arm-none-eabi-addr2line -e my-build-folder\zephyr\zephyr.elf 0x64e34

Could you post the output of the above?

Regards,

An update on this: I found this is happening consistently when i power on the headset nrf5340 audio dk, and have only the second gateway opened, without the first one. If i have the 2 gateways running or just the first gateway, i dont get this error

Thanks for the update.
