stm32F10x MSC with SPI Flash (W25Q256) problem

Hello,

I am trying make a USB device MSC.

It works fine with SD card, but I want both SD card and flash.( I set max_lun to 1.)

I have wrote the SPI_Flash_Write and  SPI_Flash_Read that can be called by MAL_Write and MAL_Read.

It seems work fine cause I can format the flash disk on my computer and put files into the disk.

However, everytime I turn off my board and turn on it, it ask me to format the disk again and again.

I have searched many solutions. Someone said that I should use FATFS f_mkfs to format first.

I tried but not worked , is that true or any other problem I missed ? 

 

Regards,

thonsha
