Dear Team and @igrr,

Thanks for the great platform you are providing us an ability to simulate and test our application.

It seems like spi_flash_mmap doesn't seems to be working. spi_flash_read and spi_flash_write works like a charm but when we mmap the region and then write to the region using spi_flash_write, mmaped region doesn't seem to have updated.

Provided some pointer, I will be more than happy to work with you to get this resolved.

Thanks.
