How to mount NAND FLASH when transplanting micropython to STM32F429IGT6 [Copy link]

 

As the title says, I am using the Zhengdian Atom development board, and it is now running, but the file system can only recognize the flash

I looked through the schematic and found a 512MB NAND FLASH that can be used, as shown in the figure

I don't know how to mount it, and I don't know if it is in the mpconfigboard.h file. I'm a newbie posting this, please help me.

If it is integrated into the firmware, you need to modify the flash definition in the source code, set spi, capacity, etc. You can also try to set spi in the user program, and then use os.mount to plug in.

I see that its pin is FMC, it seems that it can read and write data directly by accessing the address, which seems to be a little different from SPI FLASH. I searched the Internet but couldn't find a similar plug-in method

You mean SRAM, right? You can refer to the definition of STM32F769DISC development board in the source code.
