SYSBOOT[9] :0, I've tried with setting it as 1, but problem exists.
After flashing uboot and spl, while booting after SPL header print it says "omap-elm: uncorrectable ECC errors many times. Then uboot and linux are booted. When I tried to go for BCH8, serial terminal simply prints 'CCCC' continuosly. Please help.
I've mentioned my uboot commands in "steps for uboot flash.txt". Attached files are
err.txt : Error after boot
