Hi,
I compiled the demo according to
https://github.com/skalk/genode/blob/i.MX53_tablet_demo/os/src/server/vmm/imx53/README.
Next to run the demo in the SABRE tablet, I followed the instruction in
http://genode-main.narkive.com/qJXUD6w5/arm-trustzone-demo-in-i-mx53-sabre-tablet.
Created the u-boot.imx using
https://eewiki.net/display/linuxonarm/i.MX53+Quick+Start#i.MX53QuickStart-Bootloader:U-Boot
for the step 2)
2) sudo dd if=$(U-BOOT-DIR)/u-boot.imx of=/dev/sdb seek=2 bs=512 conv=fsync
But when I put in the MMC card in the tablet with the SD card in it and restart
the tablet, it just powers on to the default Android which it came with. How to
get the u-boot prompt, as mentioned in step 4)?
4) After power up the tablet, U-BOOT prompt (u-boot from MMC is not used), I
did as follows: MX53-SMD U-Boot > ext2load mmc 0:1 0x70800000 image.bin
How to get this u-boot prompt?

has a chapter 3 on various boot options.
http://cache.freescale.com/files/32bit/doc/user_guide/IMX53SMDHUG.pdf shows the
location of the switches sw26 and sw28 at the back of the board. Does that
mean, I should open the back cover of the tablet to change these? Is this what
http://genode-main.narkive.com/qJXUD6w5/arm-trustzone-demo-in-i-mx53-sabre-tablet
did?
Want to verify the correct thing to do as the tablet is expensive.
Thanks!
Riju
