EasyInstaller installation from USB stick fails

Hardware: Colibri iMX6DL 512MB IT V1.1Y, we use our own carrier board

From time to time we fail to install our WindowsCE and application via Toradex EasyInstaller script from USB stick. The colibri module resulting state is the EasyInstaller does no more start up so we cannot re-try to install from USB stick. In bootloader output we see several BOOTP broadcast tokens.

How could one force the Colibri into this state? Our script works 99% of the time, could this be a timing problem somewhere?
We can recover the Colibris by loading EasyInstaller again = factory default.

Bootloader output (this time from Toradex Colibri Evaluation Board V3.2B):

Could you please provide more details about your case

  • Does it happened to “fresh” modules (with factory flashed Toradex Easy Installer) or modules programmed with something else?
    -what script you are talking about? The wrapup.sh got invoked only when OS flashing is done so it can not affect flashing itself. The image.json is not a script but rather a configuration file.

Could you also provide a detailed repro steps so we can try to investigate this issue locally?

I’m afraid you cannot reproduce this locally because

  • we are using our own custom board
  • 99% of the setups are successfull

It happens to fresh modules with factory settings (EasyInstaller). I did misuse the term ‘script’, you are correct image.json is a config file. We do not use any scripts except wrapup.sh.

Can you please give some hints what is needed for the Colibri to go into this state where BOOTP broadcast is displayed?

Does that 1% of “failed” modules behave the same way after reboot? If so - are they behave the same way if inserted in a Colibri Evaluation board?

Yes, in fact we do not see any output of EasyInstaller while installing on our custom board/custom terminal. After a failed installation, when our application does no start up, I move the Colibri to Colibri Evaluation Board to have any bootloader output to find out what happened.

Hi @zorro ,

The modules tries multiple ways to boot. If an eMMC boot is not successful

it will try USB next:

If this failed as well then it will try to boot over the network (TFTP). If there’s nothing to boot from, the module will stay for a while in this loop to try to get a connection going.

One thing I noticed when looking at your log. Is that the USB phase discovered 4 devices? Are you possible using a USB hub between the USB stick and the module? If so, could you try without the hub?

Best Regards

The 4 USB devices are present because of catching the bootloader output I have to put the Colibri into the Toradex Evaluation Board. In our custom board there is no other USB device than the installation stick.
Maybe the installation stick is of bad quality (timing).

Hi @zorro ,

I see. Is the behaviour the same if you use a different USB stick?

Would it maybe be possible that you share a snipped of the schematic, showing how you integrated the USB port?

I can make the topic private if you prefer to not make this public.

Best Regards

Hello @zorro ,

Have you made any progress on this topic? Do you need additional help on our side?

Best regards,
