Dears:

Regarding the SOTA function, do I need to configure the registers SWAPCTRL and HF_PROCONTP separately in the application? If it is not configured, please tell me the reason。

thank you! ! !

Hello,

These registers are configured during the boot and yes you need to program both the UCBs (UCB_SWAP, UCB_OTP.PROCONTP ) corresponding to SWAPCTRL and HF_PROCONTP for SOTA swap functionality.

Thanks.

Dear:

    My understanding is that after I configure UCB_SWAP and UCB_OTP.PROCONTP in UCB, I don't need to configure the two registers in the following figure separately, because the configuration of UCBs will be read during booting and then written to the corresponding registers, I Whether the understanding is correct, please help to reply.

Thanks!!!

Hi, I highly suggest contact your FAE and ask for the application note AP32404-Tutorial_Using_the_2nd_Generation_AURIX_SWAP_mechanism_for_SW_updates_Over_The_Air_v1.1

to enable SWAP you need several steps, the application note goes into more details, and it is important to understand and follow  the steps  otherwise you might brick your device PERMANENTLY!
