I’m using ubuntu 14.04 installed in VM, Toradex version 2.6, Colibri evaluation board and i.MX7D.
Until now I used i.MX7S. From today I had to switch module and use i.MX7D.
I read again the documentation for linux image, kenel, device tree and uboot customization and compilation and i noticed that the unique part to rebuild is the device tree. It’s correct?
I inserted i.MX7D module into Colibri evaluation board and loaded all of the software component on the i.MX7D.
The boot is ok and also my application start correctly but the image on the screen is slightly flickering.
Also if i try to power off the module (with linux command “poweroff”) the module seems to power off (the screen become black) but after a seconds the “RESET_OUT” signal led become red and the screen is powered on again with various colour on it.
if i move the i.MX7D module to an Iris carrier board, this problem disappear.
If i use the i.MX7S module on the Colibri evaluation board, this problem disappear.
It seems a problem related to i.MX7D and Colibri evaluation board working together.
Thanks for any help you can give.
