"continuous activity" can you share what you actually get over serial? The BootRom on the AM335x is actually more picky than that.. Where "exactly" is the "boot" folder on the partition in raw terms? Is it fat? etc.. In the old days, when we used FAT and real files, the FAT partition must be at the very start of the medium, size really doesn't matter, we used a partition size of 96MB thru 16MB over the years. Next, after formatting, it's was always way more reliable to write the "MLO" file 1st, then the "u-boot.img"... Fun ROM bugs.. Today we just leave a 4MB hole and dd the files to a very specific address on the medium.. It's more reliable, (unless you use a Linux Virtual machine on top of Windows, then it seems to never be correctly written..) sudo dd if=./MLO of=/dev/sdb count=1 seek=1 bs=128k sudo dd if=./u-boot.img of=/dev/sdb count=2 seek=1 bs=384k Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
