Hello! I'am having a look at the ecc algorithms in nand code and I observe (both in kernel and in u-boot) that when ecc corrects some data, corrected data are given to the user, but the data storage in the nand do not change. In other words, I expected the flash would be written with the new (corrected) data.
Why data corrected by ecc are not rewrite to the flash? I think that it should be easy achieve this goal. In the read function, if ecc corrects some data on a page, I read the entire block, erase it and write back (correct) data to the flash. Nobody is interested in this feature? Or is it more difficult than I think? Thanks a lot!
