<div class="moz-cite-prefix">Hi Peter,<br>
<br>
I don't know exactly what you mean with "bootup with any boot
prompts on the console interface". But looking at your working
steps it seems to me that there is a general misconception. You
hard-copy the Genode uImage to the beginning of the SD-card but
neither represents this image a proper bootoader nor is the
bootloader assumed to start at block 0.<br>
<br>
You should instead 'dd' a bootloader of your choice to the address
that is called on SD-startup, additionally create a partition that
doesn't overwrite the bootloader, copy the Genode uImage into this
partition, and then instrument the bootloader to load and execute
the uImage.<br>
<br>
I often boot an Imx53 this way by using the Uboot bootloader. My
working steps are as follows:<br>
<br>
### uboot toolchain ###<br>
wget
<a class="moz-txt-link-freetext" href="http://releases.linaro.org/14.09/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.9-2014.09_linux.tar.xz">http://releases.linaro.org/14.09/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.9-2014.09_linux.tar.xz</a><br>
tar xvf gcc-linaro-arm-none-eabi-4.9-2014.09_linux.tar.xz -C
$MY_GCC_DIR<br>
<br>
### uboot ###<br>
git clone <a class="moz-txt-link-freetext" href="https://github.com/m-stein/uboot">https://github.com/m-stein/uboot</a> $MY_UBOOT_SRC_DIR<br>
cd $MY_UBOOT_SRC_DIR<br>
git co usb_armory_genode_tz_vmm<br>
mkdir $MY_UBOOT_BUILD_DIR<br>
make -C $MY_UBOOT_SRC_DIR ARCH=arm
CROSS_COMPILE=$MY_GCC_DIR/bin/arm-none-eabi- O=$MY_UBOOT_BUILD_DIR
usbarmory_config<br>
make -C $MY_UBOOT_BUILD_DIR ARCH=arm
CROSS_COMPILE=$MY_GCC_DIR/bin/arm-none-eabi- -j$MY_CPUS<br>
<br>
### mmc ###<br>
sudo parted $MY_MMC --script mklabel msdos<br>
sudo parted $MY_MMC --script mkpart primary ext4 5M 100%<br>
sudo mkfs.ext4 ${MY_MMC}p1<br>
sudo dd if=$MY_UBOOT_BUILD_DIR/u-boot.imx of=$MY_MMC bs=512 seek=2
conv=fsync<br>
udisks --mount ${MY_MMC}p1<br>
sudo cp $MY_GENODE_BUILD_DIR/var/run/$1/uImage
$MY_MMC_P1_MNT/uImage<br>
<br>
### boot ###<br>
# as soon as uboot came up, interrupt the countdown and do:<br>
setenv bootcmd=ext2load mmc 0:1 0x70200000 uImage; bootm
0x70200000<br>
saveenv<br>
reset<br>
<br>
<br>
Don't forget to set all the variables in my scipt appropriately.
If you have further questions, please don't hesitate to ask ;)<br>
<br>
Cheers<br>
Martin<br>
