HSE firmware installation

vikmonti7804 — Thu, 15 Feb 2024 05:41:10 GMT

Hi,

I want to install the HSE firmware, but i am facing one error with the package given C:\NXP\S32K3_HSE_DemoExamples_1_0_0\S32K3_HSE_DemoExamples\Device_Configuration\S32K344_HSE_FW_INSTALL.

error

make: *** [makefile:38: S32K312_HSE_FW_INSTALL.elf] Error 1

Kindly let me know the solution.

is there any firmware available for s32k312 for HSE fw installation?

Hi @vikmonti7804

The HSE FW can be found in S32K3 Standard Software package:
https://www.nxp.com/webapp/swlicensing/sso/downloadSoftware.sp?catid=SW32K3-STDSW-D

Open the "Automotive SW - S32K3 - HSE Firmware" and you will see all available versions including version for S32K312.

Mentioned example S32K344_HSE_FW_INSTALL shows an option how to install the firmware. I recommend to read the description:
c:\NXP\S32K3_HSE_DemoExamples_1_0_0\S32K3_HSE_DemoExamples\Device_Configuration\S32K344_HSE_FW_INSTALL\Readme.md

We also provide document AN744810 “HSE FW install for S32K3xx” which describes how to install the firmware. It can be found in Documentation in Secure Files section:
https://www.nxp.com/products/processors-and-microcontrollers/s32-automotive-platform/s32k-auto-general-purpose-mcus/s32k3-microcontrollers-for-automotive-general-purpose:S32K3

Hi ,

The HSE firmware package foe the S32K312 is only having the bin files and some interface and host files for the creation of the project. It is not the complete project like HSE demo example for s32k344.

I am also facing the issue to flash this binary of HSE firmware with the eval board debugger as well as PE micro debugger because it supports only .elf and hex file. kindly help me to flash the binary to the eval board.

HI,

the Firmware for the s32k312 is only the file like interface and host, it is not complete project which can flash the HSE firmware binary to controller like s32k344 hse demo example.

I am facing a issue to flash the HSE firmware binry to cntroller as NXP provided only .bin file, i have used the PE micro and eval board built in debugger which is unable to do so, it can support only .elf and .hex file. kindly help me to flash the .bin to controller.

The firmware is provided in encrypted form as a binary file. Yes, HSE FW installation package contains only the binary (pink) file and corresponding API headers.

For Lauterbach users, there's also HSE DEMOAPP which helps to install the firmware and examine HSE features:

But notice that the demo works with Lauterbach debugger only. It won't work with Pemicro.

As you can read in the mentioned application note or in HSE FW RM, the firmware can be installed with or without IVT.

Installation without IVT is easier but you need a tool which is able to load raw binary file to the flash which is not the case of Pemicro debugger. In this case, "with IVT" method is more convenient.

We do not provide S32K344_HSE_FW_INSTALL for each derivative. This is just an example showing how it can be done and it's up to users to create own solution (each customer has different requirements and production tools/capabilities).

What to do:
You can create new application project directly for S32K312 in S32 Design Studio. Then copy the source files from S32K344_HSE_FW_INSTALL, update HseFwHeader_StartAddress in boot_header.c. Then modify the linker file - use linker file from S32K344_HSE_FW_INSTALL as a template. If you read the readme.md file as I suggested earlier, there must be a link to the bin/pink file, so it is linked to the project.

Then, the code will only enable HSE feature flag by programming any value different from 0xFFFFFFFFFFFFFFFF at address 0x1B000000. Then all the conditions for installation are satisfied - HSE feature flag is enabled, IVT points to valid pink image in flash, so SBAF will install the firmware after next reset.

Lukas

Hi ,

If I am able to install the HSE firmware successfully, how to verify this firmware is installed in the secure memory correctly or successfully in the memory.

please let me know any method or check the memory?

Thank You

You can check bit 0 in HSE GPR status register at 0x4039C028. If it is '1', it means that "HSE FW is present and SBAF Booted HSE Firmware".

You can find this in HSE_B Firmware Reference Manual rev 2.2.

Hi,

Actually i have created a project for s32k312 but when i am running it in debug mde i see it directly jumping to default hander not going into main, can you please help with this issue, why this is happening.

i see the binary is place in flash but utest is not enabled due to not going into main.

kindly help.

Hi Lucas ,

I am not able to see this register in any peripheral window in S32DS, Can you please tell me exactly where i can see.

i can see the value 0xC1010000 at 0x4039C028 address.

Re: HSE firmware installation

lukaszadrapa — Wed, 21 Feb 2024 15:15:09 GMT

I don't think the HSE GPR is defined in peripheral structure, so it's necessary to check the memory directly. If you can see 0xC1010000 at 0x4039C028, the HSE FW is obviously not installed.

Is the HSE feature flash at 0x1B000000 programmed?

And one more thing - I can remember that that if you use "without IVT" method to install the firmware, there can't be valid IVT in the flash. Otherwise it does not work. If you loaded the pink/bin file together with some project, it's necessary to remove the IVT. Or "with IVT" method must be used.

Lukas

Hi,

I am just following the example code given for the s32k344, so i created same project for the s32k312 and imported the binary from the linker file, i see the 0xAABBCCDD at 0x1B000000 location in memory window, what can be the problem. Every thing is same as per the example code as s32k344, only i changed the memory location in linker file. Can you please help on urgent basis, or can we connect online for debugging purpose on small call.

please find the snippet of the linker file and program.

Hi,

kindly check the image attached, the header of the AB_Swap is also there in the memory so it means the firmware is flashed in the memory, the utest area has value AABBCCDDDDCCBBAA it means utest is enabled, the HSE GPR register bit 0 is not getting set, i dont know why? it means after reset the SBAF is not installing the hse firmware in secure memory region.

kindly help on urgent basis.

Hi @vikmonti7804

could you please share that project? I will test it on my side.

Thanks,

Lukas

Re: HSE firmware installation

vikmonti7804 — Thu, 22 Feb 2024 11:47:25 GMT

Please find the project.

Re: HSE firmware installation

vikmonti7804 — Thu, 22 Feb 2024 11:48:32 GMT

Please debug it and check why hse gpr register bit is not getting set and installation is not completing by sbaf.

Re: HSE firmware installation

Small problem on my side - I found that I already have firmware 2.6.0 on both my boards and it can't be erased (this feature was added in version 2.40.0). I will get brand new board on Monday and I will test it.

I checked the project anyway and I can see nothing wrong. I would just not program the HSE feature flag unconditionally after each reset.

I will let you know the results of my test on Monday.

Regards,

Lukas

Re: HSE firmware installation

vikmonti7804 — Fri, 23 Feb 2024 08:26:26 GMT

I tried the firmware with the condition on the feature flag but again the hse gpr resgiter is not getting updated.

Hi Lucas

Any update on this?

Re: HSE firmware installation

lukaszadrapa — Mon, 26 Feb 2024 12:11:55 GMT

I got new board right now. Here's the result of my test:

I was able to successfully install the firmware using your project. I just uncommented checking of the HSE feature flag. That was the only change I did.

After that, I could successfully erase the firmware using service HSE_SRV_ID_ERASE_FW.

I'm still not sure why it does not work on your side. Do you have more boards? Are all of them showing the same behavior?

Regards,

Lukas

Hi Lucas,

Can you please share your main program.

i have only one board with me and its new one.
