STM32 HAL NAND flash library bug

Posted on May 04, 2015 at 02:31

I found a bug in stm32f4xx_hal_nand.c module, in ''HAL_NAND_Read_Page'' function!

Need to change this line: 

*(__IO uint8_t *)((uint32_t)(deviceAddress | ADDR_AREA)) = 0x00; 

to this:

 *(__IO uint8_t *)((uint32_t)(deviceAddress | CMD_AREA)) = 0x00; 

I used the K9F1G08U0D flash memory, and I need to send 2 extra address bytes first (column address) So I decided to write my own driver for K9F1G08U0D, based on stm32f4xx_hal_nand.c 

Unfortunately I copied Read function with that small issue, and I spent 2 nights to figure out the problem :)
