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?

I can't fix your problem but for extra brownie points you could register this in launchpad as a bug and we can push for the right people to investigate.
Please file a bug at:

(sounds like a kernel related issue) and we will take it from there :)

Sincle I believe this is a known issue with the hardware, it could be wise to streamline the putting of bootloader and filesystem on separate devices.
Manually at least, this wasn't too hard: I ran linaro-media-create, copied the boot images onto a separate SD card to install them, then booted with the real card in a card reader attached via USB -- this works much better+faster than straight booting from the on-board MMC slot, and has the advantage that SDHC cards (or USB stick / HDD etc.) can be used. Especially if we configure the root device into the bootloader as root=UUID=<uuid>, Linux should be able to find the root fs wherever it is.
Is this feasible?
