Thanks for that. I see this is implemented in python and can write and read to the flash and this makes it use able. I was wondering if anyone had implemented it in the firmware with a FAT system so that the standard python file handing functions could be used similar to what has be done with the external flash RAM on the ESP32??SpotlightKid wrote: ↑Sun Jun 02, 2019 3:25 amhttps://github.com/SpotlightKid/micropy ... r/spiflash
Also I assume then the flash is operating as serial SPI and not as QUAD SPI??
Edit after reading the STM32F407 reference manual it looks like it doesn't have hardware QSPI
