S32R45 Evaluation Board has an external DRAM and it should be initialized in M7 bootloader

DDR tool in S32DS has been used to generate ddr-related code and kept the default configuration.

ddr_init() function was located in SysDal_InitBlockOne. There is a struct which is accessed by ddr_init's subfunction. but 0x4007C604, 0x4007C608 doesn't seem to be right position in S32R45 so that we can't access the below registers which starts from 0x403C0000(UMCTL2_REGS BASE_ADDRESS)

Hello,

This looks like a platform setup issue.

I will check who can handle this query.

Best regards,

Peter
