https://community.nxp.com/t5/MCX-Microcontrollers/RT1176-Flash-Driver-for-MRAM/m-p/2131199#M3513 <P>Hello, I am looking to flash an external MRAM and boot from the MRAM using FlexSPI qspi. I realize MRAM doesn't support SFDP therefore a custom flash driver is required. Are there existing drivers or existing tools to correctly write and implement this? I am relatively inexperienced with interfacing with external flash memory - apologies for any simple mistakes or misunderstandings.&nbsp;&nbsp;</P> Wed, 09 Jul 2025 22:38:35 GMT AnteoJ 2025-07-09T22:38:35Z https://community.nxp.com/t5/MCX-Microcontrollers/RT1176-Flash-Driver-for-MRAM/m-p/2131199#M3513 <P>Hello, I am looking to flash an external MRAM and boot from the MRAM using FlexSPI qspi.
