Have you set CONFIG_DEBUG_LL and CONFIG_TTY_PRINTK in your Linux config? AFAIK this is also needed for earlyprintk. When I want my Linux to be really verbose, I furthermore add "loglevel=10" to the command line. > Do you have any other experiment for ARM TrustZone on imx53 QSB? AFAIK, no. We have a Trustzone demo for the USB Armory currently for which you can find the Linux [1] and Genode sources [2] online. There are several topic branches in my Linux repo that correspond to the USB Armory port and document the problems that we solved in a more detailed way as the final branch. Furthermore, there is a github issue [3] were I documented parts of the development too.
