LS1043A-RGW boot failure

tmorrison — Fri, 10 Apr 2020 00:16:03 GMT

We have a custom board - largely based upon the NXP LS1043A-RGW Development board

We are using the LSDK 18.03 with some patches to be able to customize it. We are having

some problems in several different areas, but I have patched around those to try to get linux

to boot all the way.

The LSDK is flex-builder based and I have built a firmware, bootpartition, and rootfs. I load

that onto a sd card, and try to boot from that SD Card. I get this at the end:

[    3.411691] EXT4-fs (mmcblk0p3): couldn't mount as ext3 due to feature incompatibilities

I am assuming that the lsdk shouldn't have any of the problems that Linux Documentation/admin-guide/init.rst

Your Linux cannot mount the root filesystem due to certain FS feature
incompatibility. It is important how you format your SD card partitions
to put the images created by flex-builder. Use flex-installer from the
same LSDK release to populate your boot SD card. If you prefer to
format it by hand, look at flex-installer code, procedure partition_format_storage_device()
for the mkfs.ext4 invocation options. Note that you are
working with a pretty much obsolete LSDK version. You need to use
Ubuntu 16.04 on your build host for everything to work smoothly. Also, if it
is a heavily customized kernel, compare the LSDK default kernel configuration
with your one to ensure all necessary filesystem support options are
enabled.

Please keep in mind, that we can provide a very limited support to
historical (l)SDK releases. If the suggestions above do not help,
our recommendation is to move to the most recent LSDK.

Have a great day,
Platon

Hi Platon,

Thank you for your quick response.

I am using the flex-installer that came with this LSDK.

I am sorry that this was NOT clear.

I will look at hand formatting.

I am using Ubuntu 18.04 because that was required for some of

the other LSDKs that I've unsuccessfully had no luck getting it to

work with a LS1043A-RGW.

I am not sure how to "downgrade" my Ubuntu to support this?

In addition, I am using this version of the LSDK because I was given

patches from you guys (NXP/Freescale) that explicitly patch this version

of LSDK to support the LS1043A-RGW BSP. There are no supported

patches for newer LSDK's - I certainly would use them if I could.

I will update after I try hand formatting.

Tom

Hi,

I compared the flex-installer for the newest SDK with this - and there was one parameter I added.

Still no luck....

I have a couple more questions about this:

It says here that it successfully mounted it:

[    3.637912] EXT4-fs (mmcblk0p3): couldn't mount as ext3 due to feature incompatibilities
[    3.673534] EXT4-fs (mmcblk0p3): mounted filesystem with ordered data mode. Opts: (null)
[    3.681636] VFS: Mounted root (ext4 filesystem) on device 179:3.

Why it is trying to mount as ext3 first, I also did an e2fsck on this partition:

tom@newSNIPC:~$ sudo e2fsck /dev/sdd4
e2fsck 1.44.1 (24-Mar-2018)
system: clean, 71311/1479856 files, 645570/5912960 blocks

So, I am confused why it is having an issue. There is a /sbin/init (points to /lib/systemd/systemd)

Thanks in advance.

Tom

I don't think this is answered completely - still not working for me - and I have verified everything I can.

can you please answer my questions I have asked about

Re: LS1043A-RGW boot failure

Your recent inputs are not quite inline with the oirginal problem description. I particular, you are running fsck over /dev/sdd4 which should be a HDD based on it's name, but the problem is, according to what you wrote earlier, with a bootable SD card. fsck can help, but only if used in the proper way: if you can boot your system with a tinydistro ramdisk, try mounting the problematic partition by hand and running fsck on the target.

Regards,

Platon

I will try this test soon!
