Design for Manufacture at STM32WLE5CCU6

[bobcafer]

Hello ST experts and everyone,

I am a beginner on using the STM32WLE5CC series and need some support.

When using the LoRaWAN_FUOTA routine to make a product on the STM32WLE5CCU6 chip solution, DEVEUI, JOINEUI, and APPKEY need to be burned into the chip. However, it seems that KMS is enabled by default, so the last 4KB of nvm in the chip flash does not store the corresponding key value. How can I make an interface for factory production burning?

@STTwo-32   I have solved this by AT commands and reprogram app to factory bin.

Thanks.
