RT1064 external SPI flash programming

We have a custom board that use RT1064 with a 32MB SPI flash. We are going to use this SPI flash  to store the GUI resources, and use the internal 4MB flash to store the code.

We are able to program both flashs by using the MCUXPresso IDE, but eventually, we want to program them by using USB. 

So my question is: how can we program the external 32MB flash. I have gone through many documentation, including the i.MX RT1064 Manufacturing User's Guide , but I still can't figure out how to do that. Can anyone please give me more detail?

Thanks!

John

-- From my experience, it needs the developer to adjust the flashloader to support to program external flash that connects to the RT1064, as it only supports the internal flash defaultly.

Hi John, 

Not sure if you have resoved this problem yet or not.

If you see some test pad/pins on your RT1064 board for external flash, you may connect a profesional flash programmer to directly program this 32MB spi flash. You can use a Acroview AP8000 to do this job.

Thank you for your reply.

But I did see that the "MCU Flashloader reference manual ( Document Number: MCUFLSHLDRRM
)" mention external memory support on chapter 6. What's that mean?


Do you have further document about how to program the external SPI flash?

Can "MCUBootUtility" be used for this purpose?

Hi,
Thanks for your reply.
For RT1064, its internal flash is also a QSPI essentially, which connects to the FlexSPI and is packaged with the Soc together.
So the RT1064's flashloader only supports configuring this internal flash.
Hope this is clear.
Have a great day,
TIC
