Using OS Image tftp update with BSP 5.0

Technical Support
, ,
1

Hello,

We have a number of Colibri IMX6 based products in active use and would like to field update our image.

Is it possible to make a TFTP based update with BSP 5.0 linux image?
Our previous image was BSP 2.8 based. We were able to make TFTP based OS Image updates without any problems.

For BSP 5.0, it seems we need to use Toradex easy installer. We can’t do that with the modules in our product. Putting the modules into recovery mode operation would be very costly and error prone.

Looking forward to your reply
Best Regards
Rifo

Hi @rifo !

It is possible to use TFTP and boot from network: Boot from a TFTP/NFS Server | Toradex Developer Center

Does this help you?

Best regards,
Henrique

Hi,

Is it possible to change TFTP/NFS boot scenerio for updating our image?
Is it possible to take all files needed to boot from source to Colibri iMX6 with the using TFTP and boot with those files without NFS?

Best regards,

@ogusis01

It should be easy.

  • sudo unpack your *.tar.bz2 archive of your 2.8 BSP
  • sudo rm -r rootfs/* or similar to remove 2.8 BSP rootfs files
  • sudo unpack *.xz rootfs archive of new BSP to rootfs, where you had rootfs for 2.8 BSP
  • replace zImage, u-boot and dtb files in *_bin folder
  • update.sh -o xxx like you used with 2.8 BSP to create upgrade files in your TFTP root or on your USB/SD card

Hi @ogusis01 !

Although @Edward’s way could work, this is not the recommended way.

Updating an image on the field is a very critical operation. We do not have a stack/workflow for this kind of task out-of-the-box for our BSP.

Not even Toradex Easy Installer is meant to be used as an update tool.

On the other hand, Torizon (and TorizonCore) already has the update stack out-of-the-box to be used.

Maybe you want to check it:

Hi Edward, Thanks for the reply.
I’ve done all this but I’m getting an error as below when running update.sh.
“mkfs.fat: warning - lowercase labels might not work properly with DOS or Windows
Script aborted unexpectedly…”
How can i fix it?

Hi @ogusis01,

I don’t have any EMMC Colibri. Just for curiosity I tried it on
Colibri iMX6 (2.8.7 | 2020-06-10) and it worked, with warning, but it didn’t abort. If it chockes on your new rootfs, then perhaps a) you made extra subfolder in rootfs, make sure it has folders like /bin, /etc, and so on. b) script doesn’t find some dtb or some other file. c) script looks for rootfs/etc/issue containing “Colibri.IMX6”. Make sure your new BSP has the same substring in issue. d) try debugging update.sh script

Regards
Edward

Hi again @Edward

I did the checks you said, but unfortunately the output I got when I ran update.sh still didn’t change.

Output of update.sh

Moreover, when I try to flash the Colibri-iMX6 LXDE-Image 2.8.7 image to my module with TFTP, I get the following output in the u-boot terminal after “run update”.

Hi @ogusis01 !

I managed to flash a Colibri iMX6DL 512MB IT V1.1A. I based this flashing procedure on the default image from BSP 2.8 that I downloaded from the Flashing Embedded Linux to iMX6 Modules article.

I performed the steps just like listed by @Edward. With this, I have the set of files needed in /srv/tftp. The last step I did like this:

$ update.sh -o /srv/tftp

On the module, during U-Boot, we can try to run the bootcmd_dhcp command, but we get the output below:

Colibri iMX6 # run bootcmd_dhcp
BOOTP broadcast 1
DHCP client bound to address 192.168.10.47 (3 ms)

Load address: 0x17000000
Loading: *
TFTP error: 'File not found' (1)
Not retrying...
Colibri iMX6 #

We need to come up with the boot.scr.uimg that is missing. We can get this by copying the flash_eth.img with the desired name:

$ sudo cp /srv/tftp/flash_eth.img /srv/tftp/boot.scr.uimg

With this, we can successfully run the bootcmd_dhcp command and, subsequently, the update command:

Colibri iMX6 #    run bootcmd_dhcp

Hi @henrique.tx
I’ve listed all the steps I followed below. Considering that the images we use are the same, there must be a problem with the steps I followed.

Rootfs

1)sudo rm -r rootfs/*
2)sudo cp Reference-Multimedia-Image-colibri.imx6.tar.xz /Colibri-iMX6_LXDE-Image_2.8.7/rootfs (while in Reference-Image folder.)
3)sudo tar xvf /Colibri-iMX6_LXDE-Image_2.8.7/rootfs/Reference-Multimedia-Image-colibri.imx6.tar.xz
4)sudo rm /rootfs/Reference-Multimedia-Image-colibri.imx6.tar.xz

bin folder

  1. sudo rm zImage
  2. sudo rm u-boot.img
  3. sudo rm “dtb files”
  4. I copied the same files that I deleted in the bin folder from the 5.0 image with the cp command.

I’m still getting same error.

Best regards.

I don’t know what you checked and what you now. I reproduced the same unpack replace repack steps with my rootfs files for other Colibri flavor. I didn’t replace dtb files and u-boot, just rootfs and then modified rootfs/issue to contain required “Colibri.iMX6” string, which is required by your update.sh. No problems. One thing missed is perhaps requirement to run update.sh from folder with update.sh, since it uses relative path to rootfs. Here exact steps to reproduce. Starting from arbitrary folder with *.tar.bz2 in it:

# unpack
sudo tar xvf Colibri-iMX6_LXDE-Image_2.8b7.-20200610.tar.bz2
# remove old root files, Please udpate dtb, kernel and U-Boot later
sudo rm -r Colibri-iMX6_LXDE-Image_2.8.7/rootfs/*
# copy in new rootfs files from BSP5. You need to have them 
#unpacked with root rights, replace rootfs_source_folder with yours
sudo cp -ra rootfs_source_folder/*  Colibri-iMX6_LXDE-Image_2.8.7/rootfs/
# new folder for TFTP/USB files
mkdir new_tftp_files
# update.sh has to be run from the folder with update.sh. It uses relative
# path to rootfs. So cd first
cd new_tftp_files
./update.sh -o ../new_tftp_files/

update.sh output:

To flash the Apalis/Colibri iMX6 module a running U-Boot is required. Boot the
module to the U-Boot prompt and

insert the SD card, USB flash drive or when using TFTP connect Ethernet only
and enter:
'run setupdate'

then to update all components enter:
'run update'

to update a single component enter one of:
'run update_uboot'
'run update_kernel'
'run update_fdt'
'run update_rootfs'

If you don't have a working U-Boot anymore, connect your PC to the module's USB
client port, bring the module in the serial download mode and start the
update.sh script with the -d option. This will copy U-Boot into the modules RAM
and execute it.
