I mean, I can see the MMC booting vexpress-a15. vexpress-a9 still doesnt shows up. I have tried several kernels/configs combinations. v3.9 - vexpress_defconfig + VEXPRESS v3.9 - with configs from linaro sources as in this tutorial ( https://wiki.linaro.org/Resources/HowTo/KernelDeploy) v3.9 - with a config from (3.2.0-1800-linaro-lt-vexpress-a9) that I can sucessfully boot Can you guys suggest any other config I could try? Or kernel version or repo? Kind Regards, Erlon > > -- PMM >
