Hello! I have a customer’s S32K364 board here, which already has HSE configured in AB_SWAP mode. When I read the value of the DCMSTAT (0x402AC000) register, it is 0x00040FF1. According to the manual, this indicates that the DCMOTAA_EX bit is set.and the chip is in partial AB_SWAP mode. However, the manual also states, “This AB_SWAP mode is supported only for S32K328, S32K338, S32K348, S32K358, S32K356, S32K336, and S32K388." Is this a documentation error or is there another reason for this?
Hi@BianHaopeng1
看错文档了你，RN00176-for S32K396 HSE Firmware 0.2.50.0。
For the S32K394, S32K374, and S32K364 devices, 0040_0000h is not available for IVT during AB-SWAP for boot loader but the ABSWAP function should be common feature
