S32 K312 Stuck in RAM initialization

Dear supporter,

We use S32 312k, compiler is IAR. The bootloader the Occasionally stuck and not response any Diagnostic request. After Power on reset, the issue recovered.

1. When issue reproduced, attached Trace 32, the program stopped in brsStartupEntry().

2. Check the Trace list, the last command is initializing the RAM

3. Check the map file. The RAM code is not 4byte alignment in map file.

My question:

Which kind fault can trigger initialize the RAM jump to brsStartupEntry()?

If the RAM Code not 4- or 8-bytes alignment, what is the risk?

Is there any relationship between RAM Code not alignment and the stuck issue?

Thanks!

Best Regards!
