Any RT1021 Examples to Write to QSPI from RAM?

Good day All,

Are there any software examples that demonstrate how one can erase/write a sector of QSPI Flash while XIP from the same QSPI Flash?  I recognize that you cannot do this directly, but would require copying the erase/write firmware to RAM, then execute from RAM, and once complete return back to the QSPI firmware.  I thought before I start doing this I would see if there were any examples that I could learn from.  Basically what I want to do is to store some data into flash (e.g. Ethernet MAC Address, etc) and then retrieve this info upon the next reboot.

Thanks in advance!

Cheers,

Sam
