My apology, I used a model (DX1014) that we have not upstream to your repository. It is based on the Freescale P1014 unlike the DA923RC (MPC8544).

[Barbier, Renaud] Correct. The NAND driver has not been upstream for the DA923RC. I have now used the DA923RC to do the same test. With barebox from 2016.07, ubiformat gives me: OWBOOT> / addpart -n /dev/ram0 77070336@0x10000(image) OWBOOT> / ls /dev/nand0 /dev/nand0 OWBOOT> / ubiformat -q -y /dev/nand0 -f /dev/image OWBOOT> / With 2019.07, ubiformat gives: OWBOOT> / ubiformat -y -q /dev/nand0 -f /dev/image ubi1: detaching mtd0 from ubi1 ubi1: removing nand0.ubi ubi1: mtd0 is detached nand0: error -74 (ECC error) while reading 64 bytes from PEB 14:0 nand0: error -74 (ECC error) while reading 64 bytes from PEB 15:0 nand0: error -74 (ECC error) while reading 64 bytes from PEB 21:0 nand0: error -74 (ECC error) while reading 64 bytes from PEB 21:512 nand0: error -74 (ECC error) while reading 64 bytes from PEB 24:0 nand0: error -74 (ECC error) while reading 64 bytes from PEB 24:512 nand0: error -74 (ECC error) while reading 64 bytes from PEB 30:0 nand0: error -74 (ECC error) while reading 64 bytes from PEB 30:512 nand0: error -74 (ECC error) while reading 64 bytes from PEB 37:0 nand0: error -74 (ECC error) while reading 64 bytes from PEB 37:512 nand0: error -74 (ECC error) while reading 64 bytes from PEB 47:0 nand0: error -74 (ECC error) while reading 64 bytes from PEB 47:512 nand0: error -74 (ECC error) while reading 64 bytes from PEB 470:0 nand0: error -74 (ECC error) while reading 64 bytes from PEB 470:512 nand0: error -74 (ECC error) while reading 64 bytes from PEB 473:0 nand0: error -74 (ECC error) while reading 64 bytes from PEB 473:512 ubi1: scanning is finished ubi1 error: ubi_update_fastmap: could not find any anchor PEB ubi1 warning: ubi_update_fastmap: Unable to write new fastmap, err=-28 nand0: error -74 (ECC error) while reading 64 bytes from PEB 30:512 ubi1: scrubbed PEB 30 (LEB 0:28), data moved to PEB 2702 nand0: error -74 (ECC error) while reading 64 bytes from PEB 37:512 ubi1: scrubbed PEB 37 (LEB 0:35), data moved to PEB 2104 nand0: error -74 (ECC error) while reading 64 bytes from PEB 47:512 ubi1: scrubbed PEB 47 (LEB 0:45), data moved to PEB 2103 ubi1: scrubbed PEB 328 (LEB 1:33), data moved to PEB 2101 nand0: error -74 (ECC error) while reading 64 bytes from PEB 21:512 ubi1: scrubbed PEB 21 (LEB 0:19), data moved to PEB 2100 nand0: error -74 (ECC error) while reading 64 bytes from PEB 24:512 ubi1: scrubbed PEB 24 (LEB 0:22), data moved to PEB 2099 ubi1: scrubbed PEB 26 (LEB 0:24), data moved to PEB 1925 ubi1: scrubbed PEB 448 (LEB 1:153), data moved to PEB 1922 nand0: error -74 (ECC error) while reading 64 bytes from PEB 470:512 ubi1: scrubbed PEB 470 (LEB 1:175), data moved to PEB 1921 nand0: error -74 (ECC error) while reading 64 bytes from PEB 473:512 ubi1: scrubbed PEB 473 (LEB 1:178), data moved to PEB 1920 nand0: error -74 (ECC error) while reading 64 bytes from PEB 13:512 On the DX1014, ubiformat never reported an ECC errors on both 2016 and 2019 Can barebox itself read what it has written, > i.e. ubiattach / mount it? [Barbier, Renaud] DA923RC: Barebox can attach and mount, do ls and copy a file to memory and boot. DX1014: Barebox can attach and mount, do ls but not copy a file to memory. OWBOOT> / cp /bin/busybox.nosuid / could not open /bin/busybox.nosuid: No such file or directory I could upstream the DA923RC nand driver if you like but I think it may be easier for me to do a dichotomy between 2016 and 2019 and find when it went wrong. If you have any idea, let me know. Cheers, Renaud _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
