es an MTD instance to talk to the NAND (via a driver)). Looking closer, the "MTD" looks to be the drivers talking directly to the memory devices, in in nuttx/drivers/mtd. BR Thomas -Original Message- From: Alan Carvalho de Assis Sent: den 25 september 2020 16:48 To: dev@nuttx

Hi Thomas, According to drivers/mtd/README.txt the NAND support is only partial because there is not a FS to handle it correctly. Normally for NAND you will need to scan the NAND to update the bad block table during the boot (could be on NuttX or in a bootloader) to guarantee the FS will be use a

I'm trying to understand what level of NAND memory support currently exists in NuttX. The intention is to read and write files on the NAND memory. Device level support is in place, but probably somewhat out of date.  The obstacle to use NAND is that there is no NAND-compatibile file system o
