Unable to re-format the NVM and RAM catalogs with S32K344_0_2_55.0 version HSE (fullmem)

After installing the S32K344_0_2_55.0 HSE firmware on the S32K344 chip, the HSE firmware version number can be read out correctly. However, when performing the re-format the NVM and RAM catalogs operation, it returns ((hseSrvResponse_t)0xAA55A21CUL), and formatting the NVM and RAM catalogs cannot be performed. The function interface for sending information to the HSE firmware is shown in the attachment. However, on the HSE_FW_S32K344_0_2_40_0 firmware, there is no problem when performing the re-format the NVM and RAM catalogs operation.

Re: 使用S32K344_0_2_55.0版本HSE(fullmem)无法进行re-format the NVM and RAM catalogsProblem solved, it turns out that the number of SHE KEYs in the RAM slot is limited to 1. But this is not stated in the HSE release manual.Re: 使用S32K344_0_2_55.0版本HSE(fullmem)无法进行re-format the NVM and RAM catalogsRead the value of the FSR register as 0x09600000
