IMX RT 1050 Firmware update design

slimSHA — Wed, 10 Nov 2021 06:35:24 GMT

I'm a bit new to controllers.

I have a GUI application running on IMX RT 1050 based board. The boot media is SD card (will be eMMC in the future). and the application is linked with the RAM

we need to implement a firmware update mechanism. FW updates are delivered in USB mass storage devices (USB thumb drives). The user should be able to update FW by connecting the USB thumb drive to the board.

we would like to implement HAB in the future.

What is the best way to achieve this?

any suggestions appreciated

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you refer to the SFW solution.
Have a great day,

Thanks for the reply,

I was looking into SBL and SFW projects.

i built the SBL project and tried to flash it on the board.

i. Use a micro USB cable to connect the EVKMIMXRT1170 board to the computer.
ii. Set the board to serial download mode.
iii. copied the sbl.bin file to the RT1050EVK drive detected by the windows
iv. Set the board to XIP mode
v. Reset the board.

but when I copy the sbl.bin file to the device, the explorer window closed automatically and when I rechecked the drive, I found the following error in the FILE.TXT file,

"The interface firmware FAILED to reset/halt the target MCU"

I would like to know how to flash the generated sbl.bin file?.

@jeremyzhou @mjbcswitzerland

I have been looking into the SFW and SBL project.

I was trying to single image mode in SBL. for that I enabled the following from SBL menuconfig

enabled single image option
enabled ISP option

I flashed the SBL binary to the board using the following method.

set the board in serial download mode (0001 dip switch)
powered the board via USB and J-link is connected to the board and PC
opened MCU boot utility v3.3.0 and the utility detected the board successfully.
then I selected sbl.elf file as the application image file
then selected all-in-one action
after flashing, I put the board in XiP mode (0110 dip switch)
I can see the following "hello SBL.
Bootloader Version 1.1.0
Bootloader chainload address offset: 0x100000
Reset_Handler address offset: 0x10ffff
Jumping to the image"
seems the sbl.elf flashed properly on the board.
then I again connected the board to the pc (the board is still in XiP)
and executed the below blhost commands to flash sfw.bin file
blhost -t 50000 -p COM9,115200 -j -- get-property 1 0
blhost -t 2048000 -p COM9,115200 -j -- flash-erase-region 0x60100000 0x100000
blhost -t 5242000 -p COM9,115200 -j -- write-memory 0x60100000 sfw.bin
blhost -t 50000 -p COM9,115200 -j -- reset
but I'm repeatedly getting the following on the terminal

hello sbl.
Bootloader Version 1.1.0
Bootloader chainload address offset: 0x100000
Reset_Handler address offset: 0x10ffff
Jumping to the image

the document in the doc folder is a bit confusing and I could not understand why the application is not executing,

any help appreciated

Update: I was trying with raw binary. Now I created the image with the proper header. now the board is able to do SFW update with USB.
