Why RTSM terminal_0 cannot display?
For what it's worth, I'm happily building and booting Catalin Marinas's soc-armv8-model branch [1] with his latest version of the AArch64 boot-wrapper [2]. From the names you're using, it sounds like you might be using an older revision of the boot-wrapper. The devicetree files were renamed a few months ago [3] [4]. 1. http://git.kernel.org/cgit/linux/kernel/git/cmarinas/linux-aarch64.git/log/?h=soc-armv8-model 2. http://git.kernel.org/cgit/linux/kernel/git/cmarinas/boot-wrapper-aarch64.git/log/ 3. http://git.kernel.org/cgit/linux/kernel/git/cmarinas/boot-wrapper-aarch64.git/commit/?id=b4ebd41f98ed13a92e4877cd84984aeff5187734 4. http://git.kernel.org/cgit/linux/kernel/git/cmarinas/boot-wrapper-aarch64.git/commit/?id=c51dde817b5ed5b8f741b67ac51bd67bd87b4a2a Regards, Christopher -- Employee of Qualcomm Innovation Center, Inc.
