HI, I could not write data to the last sector (0x3ff000) of internal flash of RT1604 on HAB closed mode. RT1604 was hang after writing flash. I have used flexspi_nor_flash_erase() and flexspi_nor_flash_page_program() in "RT1064 Users Manual" regarding FlexSPI NOR API. Is there any restrict of memory map on HAB? Please tell me how to debug it?
