Firmware Update via External USB Drive - MIMXRT1170-EVK

[myee_]

Hi there, 

I am trying to demonstrate a firmware update via USB drive wherein the board recognizes the drive, locates the file, and writes it to flash memory for a bootloader to handle. 

I have been able to use evkmimxrt1170_mcuboot_opensource, using the GUI flash tool to manually flash a firmware file into a bootloader slot. 

I have also been able to use evkmimxrt1170_host_msd_fatfs_bm to recognize, open, and read a specific file on the USB drive. 

Based on my goal and the examples above, am I on the right track? I am unsure on how I can read the file into a buffer and then write it to flash memory at one of the bootloader's slots. Are there any additional examples that you would recommend to achieve my goal? 

Additionally, are there any resources on the evkmimxrt1170_flashloader example? I could not seem to find any associated documentation and am wondering if this could be a suitable starting point to accomplish my goal. 

Thank you in advance for your help. I look forward to hearing from you.

Hi @Kan_Li,

      When I try to compile this  https://github.com/nxp-mcuxpresso/sbl for the "serial over USB"

I'm getting the following error " #error The serial manager blocking mode cannot be supported for USB CDC." . Could you please help me to overcome this error.

Thanks & Regards.
