My Target system is an i.MX28EVK from Freescale. My first problem is the following. I applied the patches to create a u-boot.sb (secureboot) image for i.MX Platform. This image build very well but in 9 of 10 tries it fails to boot. I disconnect the EVK from Power every time a boot failed but cannot say which circumstances made it work. The second problem is a bit more frustrating. I tried to load a 3.3.5 Kernel after U-Boot boot but it fails with the message "can't open /dev/ttyAMA0 permission denied". At this point I tried everything I could imagine. I used Static device table and entered the permissions to /"target/generic/device_table.txt" and "/target/generic/device/table_dev.txt". I tried to use udev and created a file in output/target/etc/udev/rules.d with the name "50-udev.rules" which contains the following ***KERNEL="tty[A-Z]*", NAME="%k", GROUP="uucp", MODE="666"*** In both cases I tried various permissions from 644 to 777. But every time I try to boot these Kernel the error are the same. I hope anyone could help me Thanks Tobias
