Programming both MCUBOOT and Application on flash

vrg6 · ‎03-27-2019

Some background:

Have access to IAR 6,7,and 8
Have access to version 2.0.0 and version 2.5.0 of MCBOOT
Using a custom microcontroller board with a K64 chip

I have began a new project. The goal of this project is to have have MCUBOOT running in the flash memory of a K64 chip. While the bootloader is in the flash I want to have a specialized application running in the background. The intention is to use the bootloader to update and flash the application when needed.

Both the application and the bootloader have their own .ICF files to map them out to memory. However, in order to have the application and bootloader co-existing, I would need to modify the .ICF files. The Bootloader would have to exist at address 0x000 of the flash memory and the application would have to exist afterwards.

To give perspective, this project is functionally similar to how you can flash the led_demo program to address 0x0A000 using the bootloader.

Does anyone know what a good starting place is or if there is a way to automatically generate an .ICF file?

Hi Vincent,

About this area knowledge, please refer to my attached document.

Chapter 4.4 BCA utilities tab page

Chapter 4.5 Bootloader configuration page

Chapter 5.8 Integrate config file to user project

If you have time, I suggest you read all the document, you will be clear about it.

Wish it helps you!

Have a great day,
Kerry

Hi Vincent Garbonick,

Do you want to program the bootloader code and the application code together to the K64?

You can't mix the bootloader and the application code in one project, but you can generate two .hex file, then find some tool to mix two hex file together.

So, you can't use only one .icf file for both the bootloader the app project.

You still need to use two projects, different project have different .icf file.

From my own opinion, you can download the bootloader to the board at first, then use the bootloader to download your app. This is the normal operation.

Wish it helps you!

If you still have question about it, please kindly let me know.

Have a great day,
Kerry

Hello Kerry!

I see what you are saying. I have been able to get the bootloader and the application on the same flash device now by moving the start position of the application down in such a way that it does not overwrite the bootloader. However, the BCA configuration of the application is not recognized by the KinetisFlashTool. Since the BCA start-of-file information is invalid, the application code does not execute properly. Attached is a picture describing what I am saying.

How would one go about generating proper BCA information for the application so it is recognized by the bootloader and executes properly?

kerryzhou · ‎03-28-2019

Hi Vincent Garbonick,

If you don't modify the BCA area, the application code works ok or not on your side?

Do you mean, just when modify the BCA area, the app function can't work?

This is my test result:

I just disable CAN module, then generate the app again, the code still works OK.

I also attached my app bin file for your reference.

Wish it helps you!

If you still have question about it, please kindly let me know.

Have a great day,
Kerry

Hello Kerry!

What I am saying is that when our application does not have BCA information, the bootloader does not recognize the application and boot into it. We cannot get our application to work with the bootloader since it does not have BCA information programmed into the .bin image file.

We need to find a way to add BCA information to our custom project so the bootloader recognizes it.

Thanks for everything,

Vincent Garbonick

kerryzhou · ‎04-01-2019

Hi Vincent,

If your app don't have the BCA, you can generate the .bin file, then use the KinetisFlashTool to add it automatically.

Or you in the app source code, just define the BCA area, and add it.

You also can refer to the KBOOT2.0 k64 APP project:

https://www.nxp.com/webapp/Download?colCode=NXP_KINETIS_BOOTLOADER_2_0_0&appType=license

Folder: NXP_Kinetis_Bootloader_2_0_0\apps\led_demo\MK64F12

Wish it helps you!
Have a great day,
Kerry

Hello Kerry! Thank you for all your help so far. I was able to follow the steps as you said, but now I am having trouble properly setting up the linker file in order to accept the bootloader configuration information. I added the bootloader_config.c to my project and changed the start address to 0x000A000. I modified the linker file and have been having errors.

I attached a picture of the error message and the linker file. Thank you for your continued support.

Hi Vincent,

What's the code you put in bootloader_config.c ?

Why you define the cstack as 0?

Could you also share the linker file before your modification, and which don't have the build problems?

Have a great day,
Kerry

I do not know why I set cstack to zero.

Thanks,

Hi Vincent,

If you don't add the bootloader_config.c , and relocate your code to 0xa000, do you have the build linker errors?

If you are convenient, you can share me your project which can reproduce the problem. You can deleted all the important code to you, just leave the project which can reproduce the problem.

Have a great day,
Kerry

Hello Kerry,

I am not able to post the full project because it is proprietary in nature at the moment.

When the bootloader_config.c code is not included, the code still gives the same error, which leads me to believe is is an issue with the linker file.

kerryzhou · ‎04-07-2019

Hi Vicent,

I understand you can't post the project.

If you don't add the bootloader_config.c , it means your linker file modification have problems.

Now, please modify your problem linker file like this:

Hello Kerry,

The startup.s code was already in the bootloader project. That is not the issue however. The BCA area is defined in the linker file and the bootloader_config.c file is included in the application project. When I check the map file, the issue becomes apparent. The BCA information should be placed right after .intvec start, but instead it is appearing at an improper address (0x000bf5f8).

I have tried explicitly telling the linker file where to place the application code to no avail. Attached are images of the map file and the linker file used. The red boxed area is where the BCA area SHOULD be. The second photo is where the bootloader_config.c is ACTUALLY showing up.

Hi Vincent,

I know you already define the .s, that's why I let you define the BCA area in the .s directly, just like our bootloader app sample code startup_MK64F12.s, this method will allocate the BCA area in the correct address.

You can try it on your side.

I think your problem still in the IAR function detail address allocation side.

Please try the official startup_MK64F12.s on your side, and don't use your bootloader_config.c.

Whether it works ok or not?
Have a great day,
Kerry

Hi Vincent,

You can delete all the important code to you, still use your original project without the .s modification, then delete all the API function important to you, just give me the simple project, I will help you to check it on my side.

Waiting for your updated information.

Have a great day,
Kerry

Hello Kerry!

I have good news. The startup_config.s file you shared works correctly in the application code!

However the problem now is that I don't know how to further configure the bootloader options. I would like to enable the "tag" "direct boot" and "timeout" options but do not know how to begin editing the startup_config.s file.

Hi Kerry,

That's not really what I meant. I was wondering how you could set these options

in startup_config.s code. I don't know how I would go about changing the hex values in a way that affects the BCA information.

Thanks,

Vincent
