HSE FW Update

ssean — Tue, 23 Sep 2025 05:26:21 GMT

Dear NXP Team

I am trying to perform an HSE FW Update (0.2.6.0 → 0.2.55.0).

Using the HSE_DEMOAPP_S32K312_0_2_55_0 program, I proceeded as follows.

1. Load menu.cmm

2. Load demo app binary

3. Load demo app symbol

4. Run demo tests

5. HSE FW Update - Update HSE FW - One Shot Mode

6. Select s32k312_hse_fw_1.13.0_2.55.0_pb250129.bin.pink

Afterwards, when reading the version, the output is shown as below.

Has the FW update been performed successfully?

BRs,

Sean Sung

Hi Sean Sung,

According to the gHseFwVersion in ssean_4-1758605150886.png, the current HSE FW is S32K312 AB_SWAP 0.2.6.0

Did you follow the steps shown in section 6.4.3. FULL MEM to AB SWAP HSE FW Update of HSE_DEMOAPP_S32K312_0_2_55_0_ReadMe.pdf?

C:\NXP\HSE_DEMOAPP_S32K312_0_2_55_0\HSE_DEMOAPP_S32K312_0_2_55_0_ReadMe.pdf

Best Regards,
Robin

Hello @Robin_Shen

I executed it in the same way as described in section 6.4.3. FULL MEM to AB SWAP HSE FW Update of the HSE_DEMOAPP_S32K312_0_2_55_0_ReadMe.pdf file.

The currently installed version is 0.2.6.0 AB SWAP.
Is it correct that FW update from 0.2.6.0 AB SWAP to 0.2.55.0 AB SWAP is possible?

BRs,

Sean Sung.

Did you updated the SBAF to 0.15.0 by follow the steps shown in section 6.3. Secure BAF Update of HSE_DEMOAPP_S32K312_0_2_55_0_ReadMe.pdf?

I did not update the SBAF.
The current SBAF version is as shown below.

Is updating the SBAF 0.15.0 mandatory?

According to the Table 168. SBAF and HSE Firmware version compatibility for S32K312, S32K342, S32K322 and S32K341 devices of RM758225-RM00286 HSE-B Firmware Reference Manual - V2.5(2.5).pdf. It shows Fully Compatible.

After following the steps in 6.4.3. FULL MEM to AB SWAP HSE FW Update (the steps you mentioned in your question), did you follow 6.4.4. AB SWAP to AB SWAP FW Update, which requires "Activate Passive Block"?

After update finished, I see that gHseFwVersion has been updated to 0.2.55.0 and SBAF has been updated to 0.15.0.

Dear @Robin_Shen

After executing section 6.4.5 “Activate Passive Block”, the update was completed.

Thank you for support.
