NRF53 CP_NETWORK is not starting.

[burimaliu]

With the NRF53 DK Board I have written a Firmware to use the CP_NETWORK for Bluetooth and this is working properly.

In our Company Dev Boards with NRF53 i had to enable the config "CONFIG_NRF5340_CPUAPP_ERRATUM19=y" to be able to run CP_APPLICATION part.

This anomalie is present at IC Rev. Engineering A, build codes QKAA-AB0.

But  the CP_NETWORK is still not running, but i cant find if an CONFIG is needed to be enabed for the build code s"QKAA-AB0"?

 Just to be clear here, you are having issues with your custom board, and this custom board is using a nRF5340 Engineering A IC?

Engineering A is not support in the latest NCS versions. I recommend that you upgrade your custom boards to use nRF5340 IC revision 1.
