Hi Roger,
I was looking to test my system against U-Boot 2023.04. I'm running an
OMAP 4460 SOM (I've been waiting to get kernel acceptance before U-Boot,
but that has slipped) and it boots from NAND.
When I jumped from 2023.01 to 2023.04, I noticed I get spammed in the
SPL by "omap-elm: uncorrectable ECC errors". I bisected, and this seems
to be the result of commit 04fcd25873 ("mtd: rawnand: omap_gpmc: Fix
BCH6/16 HW based correction").
Is the multi-sector ECC generation something that should work in a
backward-compatible way? Do you know of anything that might be going
wrong here?
Any advice would be greatly appreciated, as I find it is usually
something simple I'm doing wrong that is causing most of my issues.
Thanks,
Colin Foster.

The patch wasn't supposed to break anything. I do not yet know what could be wrong. Most likely a wrong ECC configuration is being used. Could you please share what ECC configuration you are using on your board?

I know when I was trying to get this working I had to play with these values quite a bit.

I just made a change to CONFIG_NAND_OMAP_GPMC_PREFETCH as a test, which didn't fix the issue.

I see that you are using 16-bit NAND. One more difference in u-boot configuration. For me: CONFIG_NAND_OMAP_GPMC_PREFETCH=y Not sure if that matters but let's keep it set for now. For debug can you please apply the patch (at end) to u-boot at commit a95410696d21 (before breakage) and run the test. Test procedure: > nand dump 0 > mmc dev 0 #replace 0 with whatever points to SD-card > nand read $loadaddr 0 800 #loadaddr is any address in RAM which is free for use. > fatwrite mmc 0:1 $loadaddr nand.org 800 - restore NAND page 0 > fatload mmc 0:1 $loadaddr nand.org > nand write $loadaddr 0 800 Now please run the below test on the offending commit 04fcd25873 after applying the patch (at end). > nand dump 0 > mmc dev 0 #replace 0 with whatever points to SD-card > fatload mmc 0:1 $loadaddr nand.org > nand write $loadaddr 0 800 Please send me the logs of both tests and the nand.org file so I can try it out here.

Thanks! All are attached. However I have some other initial findings: I swapped in just U-Boot (not the SPL) with your patch, and everything seems to work! The issue of Uncorrectable ECC errors spam came from the SPL. Here's a snippet of the boot log with the "ecc" print as well as your patch: U-Boot SPL 2023.04-00029-g26a9ce5314-dirty (May 17 2023 - 12:06:49 -0700) OMAP4460-GP ES1.1 Trying to boot from NAND ecc: 2420106 ecc: ebd922f6 ecc: 333f844f ecc: ab812f72 omap-elm: uncorrectable ECC errors omap-elm: uncorrectable ECC errors omap-elm: uncorrectable ECC errors omap-elm: uncorrectable ECC errors ecc: 2420106 ecc: ebd922f6 ecc: 333f844f ecc: ab812f72 omap-elm: uncorrectable ECC errors omap-elm: uncorrectable ECC errors omap-elm: uncorrectable ECC errors omap-elm: uncorrectable ECC errors Historically when I saw "uncorrectable ECC errors" that meant I should grab a cup of coffee, problems were going to happen. However, in this scenario, if I let the SPL spew the ECC error prints, it eventually loads U-Boot from NAND. And U-Boot successfully loads the kernel, DTB, and boots the filesystem (with the "ecc: %x" prints slowing things down right now) Here's where U-Boot loads the DTB: Loading file 'boot/omap4-ia-decoder-card.dtb' to addr 0x88000000... ecc: 0 ... Repeated over and over ... ecc: 0 Done Unmounting UBIFS volume rootfs-a! So I'm thinking either: 1. I'm doing something horribly wrong and have been getting away with it. The patch simply highlights this. Or... 2. There's an issue with how the SPL is determining ECC errors, and it is incorrectly reporting errors. I hope this information is useful, and let me know if there are any other tests I can run.

We have a stripped down driver "am335x_spl_bch.c" that deals with NAND at SPL. I haven't really looked much at that driver but it relies on omap_gpmc.c for ecc.hwctl() read_buf() ecc.calculate() We didn't do any functional change to these functions in commit 04fcd25873 unless something slipped through the cracks.

They should all have been 0. Interesting. With the "ecc" prints in U-Boot I also get some non-zero values: ecc: 0 ecc: 6bff997b ecc: 6bff997b ecc: 6bff997b Once I'm booted, I can use nanddump.

I'll take a look at am335x_spl_bch.c and look at what I'm doing different.

Yes, this is correct. I intentionally left my MTD Partitions out of the kernel patch, since I don't want any changes I might make to the flash partitions to require further patches. I'm currently at this structure (SPL, 2x U-Boot, and main UBI with A/B partitions and 2x U-Boot Envs) The SD Boot version of U-Boot doesn't use NAND, so it might have a stale partition layout that I'll need to remove / modify. > > 2) > #define CONFIG_SYS_NAND_U_BOOT_OFFS 0x20000 > #define CONFIG_SYS_NAND_U_BOOT_OFFS_REDUND 0x1a0000 > > These don't seem to match what you have defined in MTDPARTS_DEFAULT. > Which one is correct? This matches the above partition layout. 0x180000 + 0x20000 = 0x1a0000. It wasn't until recently I realized I needed to remove CONFIG_SPL_RAW_IMAGE_SUPPORT in order for this fallback to succeed. > > How do you flash the MLO and u-boot image to NAND? I boot to from SD card, then run a commissioning script that contains: ``` echo "Erasing MLO partition $MLO_PART" flash_erase $MLO_PART 0 0 echo "Programming MLO partition" nandwrite -a -p $MLO_PART $MLO_FILE echo "Erasing U-Boot partition $U_BOOT_PART" flash_erase $U_BOOT_PART 0 0 echo "Programming U-Boot partition" nandwrite -a -p $U_BOOT_PART $U_BOOT_FILE echo "Erasing U-Boot redundant partition $U_BOOT_PART_REDUND" flash_erase $U_BOOT_PART_REDUND 0 0 echo "Programming U-Boot redund partition" nandwrite -a -p $U_BOOT_PART_REDUND $U_BOOT_FILE echo "Clearing UBI partition" flash_erase $UBI_PART 0 0 echo "Formatting UBI partition" ubiformat $UBI_PART -y ubiattach -p $UBI_PART echo "Making UBI volumes" ubimkvol /dev/ubi0 -N env1 -s 0x40000 ubimkvol /dev/ubi0 -N env2 -s 0x40000 ubimkvol /dev/ubi0 -N rootfs-a -s 0xc000000 ubimkvol /dev/ubi0 -N rootfs-b -s 0xc000000 echo "Writing rootfs partitions" ubiupdatevol /dev/ubi0_2 $ROOTFS_FILE ubiupdatevol /dev/ubi0_3 $ROOTFS_FILE ``` For all these tests I've been manually running the flash_erase / nandwrite process for the SPL / U-Boot partitions. > > I tried on AM335x-EVM and it works fine both before and after commit 04fcd25873. > > Once change I had to do was to increase the u-boot partition size > as u-boot image does not fit in original partition size. > > -----boot log follows----- > > U-Boot SPL 2023.01-rc4-00381-g04fcd25873-dirty (May 19 2023 - 15:10:15 +0300) > Trying to boot from NAND > > > U-Boot 2023.01-rc4-00381-g04fcd25873-dirty (May 19 2023 - 15:10:15 +0300) > > CPU : AM335X-GP rev 1.0 > Model: TI AM335x EVM > DRAM: 512 MiB > Core: 156 devices, 17 uclasses, devicetree: separate > WDT: Started wdt@44e35000 with servicing every 1000ms (60s timeout) > NAND: 256 MiB > MMC: OMAP SD/MMC: 0 > Loading Environment from FAT...

I got pulled away from this before I could figure it out, but I have an idea. I suspect the ECC calculation is working as expected. It is just that now it is pre-calculating the ECC for regions that my flash writing was simply ignroing (just leaving erased). Previously the ECC would only be calculated for pages that were correctly written, so wouldn't cause any issues. I do need to verify this hypothesis, but admittedly don't know how soon that'll be. (I won't be near hardware for at least a week) > > Michael ^ permalink raw reply [flat|nested] 14+ messages in thread
