I am working with a board that has 2 CFI-compliant Spansion S29JL064H flash memory devices. Each device is 64 Megabit (8 M x 8-bit / 4M x 16-bit) in size.

The two flash memory devices are connected in "parallel", effectively doubling the word size while maintaining the total number of sectors, i.e.,

Should I expect u-boot's common CFI driver work with this configuration?

Yes, of course.

Best regards,

================================================================ Wolfgang,

Thank you for responding. I suspected the CFI should work. Now all I have to do is figure out what's wrong with my configuration, which is shown below:

#define CFG_FLASH_CFI 1 /* flash is CFI conformant */ #define CFG_FLASH_CFI_DRIVER 1 /* use the common CFI driver */ #define CFG_FLASH_EMPTY_INFO /* print 'E' for empty sector on flinfo */

#define CFG_FLASH_BASE 0xff000000 #define CFG_MAX_FLASH_BANKS 1 /* max num of memory banks */ #define CFG_MAX_FLASH_SECT 142 /* max num of sects on one chip */ #define CFG_FLASH_SIZE 0x01000000 /* 16 MByte */ #define CFG_FLASH_ERASE_TOUT 8000 /* Timeout for Flash Erase (in ms) */ #define CFG_FLASH_WRITE_TOUT 5 /* Timeout for Flash Write (in ms) */ #define CFG_FLASH_LOCK_TOUT 5 /* Timeout for Flash Set Lock Bit (in ms) */ #define CFG_FLASH_UNLOCK_TOUT 10000 /* Timeout for Flash Clear Lock Bits (in ms) */ #define CFG_FLASH_PROTECTION /* "Real" (hardware) sectors protection */

When I enable debug in the drivers directory by setting

CFLAGS += -DET_DEBUG -DDEBUG

in drivers/Makefile, I see the following as u-boot-1.2.0 starts up:
