HSE_SRV_RSP_NOT_SUPPORTED when update HSE FW

(1) I had downloaded s32k3x4_hse_fw_1.5.0_2.1.0_pb220625.bin into S32K314 flash at 0x40_0000 by JLINK.

(2) After power off and power on again, I get 0x000000C1 from the 0x4039C028 address. So it means that “HSE FW is present and SBAF Booted HSE Firmware”.

(3) I also get 0x657669746361746F from the 0x1B000280 address. So it means that “HSE FW OTA feature is enabled”.

(4) Hse_Ip_GetHseStatus returns 0x0920

(5) But when I call Hse_Ip_ServiceRequest with HSE_SRV_ID_FIRMWARE_UPDATE, I get HSE_SRV_RSP_NOT_SUPPORTED. Does it mean that I cannot update HSE FW with the same version which is already in S32K314? I need to test my boot loader to check that my boot loader can update HSE FW successfully every time or not.

(6) The data pointed by hseSrv.firmwareUpdateReq.pInFwFile is in non-cacheable 0x20431C6C-0x20431CAB

(7) Hse_Ip_Init is called already before calling Hse_Ip_ServiceRequest.

Hi @CarlOfVmax

It is not possible to update the HSE FW to an older or the same as the installed version, always is going to cause an error as you are having.

Hello VaneB....are you sure that it is not possible to update to the same version? I'm asking because I'm updating a S32K312 with a 2.6.0 version issuing again the 2.6.0, and the service said that is Ok.
