Hi, I compiled the demo according to https://github.com/skalk/genode/blob/i.MX53_tablet_demo/os/src/server/vmm/im.... 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-t.... Created the u-boot.imx using https://eewiki.net/display/linuxonarm/i.MX53+Quick+Start#i.MX53QuickStart-Bo... 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?
https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&am... 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-t... did?
Want to verify the correct thing to do as the tablet is expensive.
exactly, you have to toggle the boot-switches according to Freescales documentation of this board to boot from SD-card instead of internal MMC. You can only access those SW26/28 switches by opening the tablet's case.
