Hello,
-> On my target board I have a spansion GL064M flash device.
We use this chip too and it works fine using U-boot's CFI. What is your sector layout (uniform, bottom boot or top boot)? The additional markings on the chip will tell you.
-> I cannot erase, write to flash by implementing the appropriate command sequences with mw (memory write ) command provided by u-boot that came with my sdk (u-boot 1.1.4).
Do the U-boot 'protect' and 'erase commands work? If so, why torture yourself with low-level access? If not, you have a configuration or hardware issue which we can explore.
