Bootloader to flash the external QSPI flash

EmbeddedTech · ‎02-19-2024

Hi,

We are using a custom board with iMXRT1062 and would like to add bootloader for flashing the external QSPI flash. I saw the app note AN12604SW for adding secondary bootloader to the application. It has an example for iMXRT1050. Is there an example available for iMXRT1060 or what changes should I make in the 1050 code in order to test in my board.

Thanks.

Hi @EmbeddedTech ,

Already finished the iar app version, you can try it on your side.

the code iar app.zip :

Hi @kerryzhou,

Thanks a lot for your patience.

Now I am able to program my board using the 'ota bootloader' after following the instructions for iar.

Also, I have tried the 'RT1170 SBL ISP download SDRAM APP' and it works fine on my board.

I would like to check with you, which of the above method is good to follow in my project. Are there any advantages of one over the other?

Thanks again.

Hi @EmbeddedTech ,

It's totally determined by your own choice, in fact, both can be used, just for your own feeling, which one is more easy to use to your own choice.

Anyway, both method works on your side now. So, just choose it by yourself. SBL+SFW can support more ota method, you can check the sbl document, so, you can choose it by your own usage.

Wish it helps you!

Best Regards,

Kerry

I am not sure if the header data is included in the above as mentioned below,

2.1.3 linker file modification

In the evkmimxrt1060_iled_blinky_debug.ld, add boot_hdr, length is 0X400.

We can use the MCUXpresso IDE linkscripts folder, add the .ldt files to modify the linker file.

Here, in the project, add one linkscripts folder, add the boot_hdr_MIMXRT1060.ldt file, build .

Your help on this is highly appreciated.

Thanks.
