Hi all,
We are using a Colibri T20 board embedded into a custom Key’ Touch Device.
Currently, it is working under WinCE and we expect to migrate it under a linux system with Yocto.
First at all, we’re trying to flash the Toradex example linux images.
- I have downloaded the Colibri_T20_LinuxImageV2.3 image.
I set the board into RecoveryMode and I simply executed:
./update.sh -r 512 -v V1_2
It took few minutes to upload everything. I set the board in nbormal mode. Reboot. Everything works, I got the Linux Angstrom loaded.
- I’ve then downloaded the Colibri_T20_LinuxImageV2.6 (beta) image.
At first glance, I noted that the flashing tool were different. t20_nvflash for the image 2.3 and tegrarcm for the latter.
I had to execute this command:
update.sh -r 512 -v V1_2 -d
I got the following output:

It took 3 or 4 seconds max.
So, I assume that the roofts was not flashed at all.
I reboot the device, and it is still the Linux Image 2.3 that is loaded.
As far as I know, the update.sh script does not have the same behavior at all ?
Have I done something wrong ?
Any idea to flash the linux image correctly ?
Thanks.
