Also, the NAND image must be padded, and the usb serial download image does not require padding. Note that the nand image has no DCD's, and the serial download (USB) image has DCD's. Here is the serial download command to boot using uuu: SDP: boot -f u-boot-usb-signed.imx SDP: write -f u-boot-nand-signed-pad.imx -ivt 0 Use the following uuu commands to boot the image during hab_failsafe:.Use hab_rvt_failsafe patch for hab_failsafe in U-Boot.Use NAND boot image, not serial download image which has DCD's. The following in your CSF file makes no difference so I did not change ours (this was the only other difference between your CSF file and our two CSF files):Ĭhanges required for hab_failsafe boot (to summarize): So the hab_failsafe boot works with the same U-Boot image as the NAND boot image, which does not work with the serial download boot. How was one to know this? I made the assumption that hab_failsafe would be the same as serial download, but it is not. Apparently including DCD's also breaks the hab_failsafe boot. Using your new CSF file does not change that. With some modifications, your last post does work.ĭCD's are required for serial download boot.
