I’ve been using an iMX7DL on an Iris carrier using WEC2013 1.1b4 and I can use a USB mouse and keyboard connected through a hub.
I’ve changed the iMX7DL for an iMX7S and the USB no longer works. The Iris, mouse and keyboard are fine. I can’t even press Space to enter the bootloader menu when prompted.
Any suggestions would be welcome.
