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?
