Hello,
I am using U-boot with Atmel SPI flash AT45DB321D. After erase command (using sf erase) and reading the first page (sf read) in the block, I see that the whole page is filled with 0xffff... ( just as expected) But then on writing any byte in any offset in the page (using sf write) and reading the page after that to see its contents, I see that the specific byte value is correct, but surprisingly I also see values of other bytes in the page (in different offset) which were written before the last erase. I would like to ask if anyone is familiar with such kind of problem before I get more deeply into the atmel driver.
Best Regards,
Ran
