When the power is first turned on, it should boot straight through to Linux. UEFI offers a 10 second window during which you can interrupt the boot sequence by pressing a key on the serial terminal, otherwise the Linux kernel will be launched. In order to reach the Linux shell you must attach a Linux "filesystem":https://releases.linaro.org/14.06/android/images/armv8-android-juno-lsk/#tabs-2 via USB. If no filesystem is attached then Linux will boot as far as it can and then announce that it is waiting for a filesystem to be attached. @@ -123,7 +123,7 @@ The Mali GPU in Juno is able to use a variety of texture compression formats, ma 1.
