HSE_SRV_RSP_GENERAL_ERROR

I tried to request SHA256 hash calculation using the HSE module in the S32K312. With the RTD 3.0 package, I encountered the error code HSE_SRV_RSP_GENERAL_ERROR, but when using RTD version 2.0.3, there is no error, and the hash is correctly calculated.

Some details are as follows:

HSE version: HSE_FW_S32K3XX_0_2_6_0
RTD version: SW32K3_RTD_R21-11_3.0.0_P07_D2306

Hi @Lixinyu

The most common reason for this error is data cache memory. Are you sure that all the data objects used for communication with HSE are forced to non-cacheable memory? Or did you try to simply disable the data cache completely to see if it makes a difference?
