Hello, I am trying to use my stm32f4discovery board with MX25L800 dataflash memory, through SPI and SmartFS file system.
I installed a NuttX driver for this memory type and I am having problems making this memory work. I cannot format the memory. Here is the output on the console, with FS Debug enabled and the commands used: ABCDF smart_scan: Entry smart_scan: Scan sector 0 ... smart_scan: Scan sector 511 smart_fsck: Entry smart_fsck_directory: ERROR: Invalid phys sector 65535 smart_readsector: Entry smart_readsector: ERROR: Logical sector 0 not allocated smart_scan: SMART Scan smart_scan: Erase size: 4096 smart_scan: Erase count: 256 smart_scan: Sect/block: 2 smart_scan: MTD Blk/Sect: 8 SmartFS initialized INFO: mx25l MTD Flash driver initialized up_rtc_getdatetime: Warning: PCF8563 RTC integrity is not guaranteed (bit 7 in VL_SECONDS register is set) .
