XIP write flash support

[zaricchou]

I am using RT1052 with a en25q16a which is a nor flash as a boot flash(connected to flexspi).Trying to place the bootloader and app in a en25q16a.But rom api earse operation could make the core in halt,while the initialization was successful.  

Is there any suggestion to solve this problem?

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) Is there any suggestion to solve this problem?
-- I'd like to suggest you use the FlexSPI drivers from the SDK library instead of the ROM API, further, it needs to relocate the driver into the RAM prior to calling them.
Have a great day,

I have changed to Flexspi drives , and relocating it to ram.

Now somethings new.

Init -------works

page program  ----works

erase operation -------not halt the core ,but not works.

Hi,
Thanks for your reply.
Do you mean the values in the flash area change nothing after erasing operation?
And I was wondering if you can upload the modified FlexSPI driver.

Hi,

Thanks for your reply.
I think you'd better upload the demo to the community, or share the download address if you upload it to some cloud drive platform.
