about bootloader example in MTB

[Tim_Shih]

Dear Receiver,

In the attached file 1, I selected a basic_boot_loader example code to import to the MTB.

In the attached file 2, after import basic_boot_loader example code to MTB, there a 2 projects generated.

#1. MCUboot-Based_Basic_Bootloader_1.blinky_cm4. " This project compiles fail and you can see there are 2 error messages in the attached 2".

#2. MCUboot-Based_Basic_Bootloader_1.bootloader_cm0p. " This project compile ok! "

Could you please help me to check why *.cm4 project complies failed ?! I didn't modify anything. I just keep this example code original. 

Thank you so much.

I have the same result. My error message is: "can not find mbedtls/sha256.h". Do you have same error message?

[Tim_Shih]

NO, my error message is shown in the MTBbootloader2.JPG. 

It's an built-in sample project in MTB. I think it should be no problem. 

I feel so confused about this. Thank you so much.

Hi ~ I found in the following link is a step by step manual for this bootloader example code.

https://github.com/Infineon/mtb-example-psoc6-mcuboot-basic

But it seems not very clear enough. Because I run this command but it can't work.

python -m pip install -r requirements.txt

Because python is not in the <mtb_shared>/mcuboot/<tag>/scripts directory.

So I still feel very confused about how to build this project successfully.

Thank you so much.

Hi：

Did you update your library? Maybe you can try it.  And Today I will copy my colleague project to compile . So please wait for moment, I will give you answer as soon as possible.

Thanks

ok,,,

How to update library ?! do you mean "library manager" ?!

Just press the "Update" in the Librarys sheet in library manager ?!

Thank you so much.

Hi:

I have resolved this issue. First, you need to install python3.8.3. If have already install other version, please uninstall it ahead. Second,  run the following the command in specific folder, for example "C:\Users\YuZh\project\mtb_shared\mcuboot\v1.7.0-cypress\scripts" : python -m pip install -r requirements.txt. Then you can compile it again. 

Good luck.

Thank you!

it looks like something in the library is referencing functions defined in the emfile source code where the configuration is:

emfile/Config/FS_ConfigMMC_CM_HS.c

Im insanely lost on this, i hope this is just some simple flag or something i am missing in the cmake file.
I hope this is okay to post here, this is after all trying to use an embedded file system library on an embedded MCU.
