Just curious, this bad sectors appeared during regular device operation or just after sysupgrade? I am asking because it could be "false positive" bad sectors. Couple of weeks ago I flash one rb411 with wrong image. I used image for flash chips with 512-bytes pages, while the board was equipped with flash chip with 2048-bytes pages. And after reboot kernel printed a lot of "bad sector" messages. Actually sectors was fine, but using of the wrong firmware image lead to corruption of OOB data of several pages. I solved this issue by flashing back the vendor's firmware with help of netinstall, this action had recover flash OOB. Then I flash the device again, but now with the correct LEDE image and it works! Looks like that the similar results could be reached with _nandwrite_ utility, but I did not try it. -- Sergey _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
