Hi.
I have a Cortex A9 vexpress board and I've been trying some of the headless
daily builds as described here :
https://wiki.linaro.org/Platform/QA/TestCases/HeadlessVexpress.
The instructions are based around the MMC card with uboot, kernel and rootfs
all loaded via this interface.
I've had mixed results. When the box completes the boot the basic systems seem
to work ok (I can get an IP and poke the filesystem). It still takes several
minutes to get to a prompt as mentioned on the wiki page.
It happens quite often that the box does not get to a prompt at all. It fails
to read the MMC properly. Below is two separate cases where reading the
partition table fails. In the first case it finds one partition and in the
second case it fails to find any partitions. The boot monitor has no problem
reading uboot, kernel or initrd from the MMC when writing to internal FLASH.
I've also tried a different SD card with similar results. Sometimes it works
fine and other times it reports I/O errors. I've tried the daily builds for 6,
8 and 10 October. Is this a known issue?
