Hi:
I use the S32K312 chipset for my project.
1. I have use the FreeRTOS and the version of RTOS is V10.4.6
2. The MCU have been install the HSE firmware s32k3x2_hse_fw_0.13.0_2.6.0_pb221129.bin.pink
3. I used the HSE firmware update service call HSE_SRV_ID_FIRMWARE_UPDATE to update new HSE version. The new version is s32k312_hse_fw_0.13.0_2.40.0_pb230730.bin.pink.
4. My MCU is used the FULL MEM type. Not use the AB_SWAP type.
5. My update HSE firmware source code shown as below.
6. After doing the HSE_FwUpdReq(), The HSE firmware could be update success. I can got the return code 0x55A5AA33UL. But I have got the hard fault during the HSE firmware update. My HardFault_Handler() shown in below. The hard fault doesn't reboot directly. So the HSE_FwUpdReq() can finish and got the success return code 0x55A5AA33UL.
7. I try to implement some code in HardFault_Handler for backtrace dump. So I got the backtrace information like below.
HSE_FwUpdReq accessMode=0x00, pInFwFile=0x00440000, streamLength=0x00000000
FW: S32K312_Application, HW: 0xc3, SW: 9.999_2023-11-25

8. Parser the backtrace address shown in below. The bus fault cause by the FreeRTOS API xTaskIncrementTick()

9. Does it because that call the HSE firmware update service then cause the FreeRTOS xTaskIncrementTick() can't increment the tick? Do you have any suggestion? Thanks you!
