github repo for mcu_bootloader middleware

[mastupristi]

Hi,

on github is the mcux-sdk repo (https://github.com/nxp-mcuxpresso/mcux-sdk). By itself it does not contain everything that the SDK produced with the SDK builder does. Some middleware are provided as separate repo (e.g. https://github.com/nxp-mcuxpresso/mcux-sdk-middleware-sdmmc or https://github.com/nxp-mcuxpresso/mcux-sdk-middleware-usb)

I am interested in what I find in middleware/mcu_bootloader (for example of SDK 2.15.000)

I cannot find these files (e.g. bl_main.c) in any repository

Can you tell me in which repository you have stored the middleware related to mcu_bootloader?

regards

Hi @mastupristi 

Sorry, the relevant code for mcu_boot is in our internal repository. Unfortunately, our mcu boot code has not been pushed to Github, so you can only refer to the code in SDK.

Hope this will help you.

Hi @Harry_Zhang 

Can you confirm that the source files I find in the SDKs in the middleware/mcu_bootloader/ directory, and which are used for examples such as evkbmimxrt1170_flashloader_cm7:

are the ones used to get the flashloader executable that is used by Secure Provisioning Tool
