[U-Boot] random errors in kernel or rootfs;u-boot check sum

9 Jul 2012


      Hi,
I'm working on a recovery tool for an overo COM where I can boot all
the way into into Linux over USB. This is similar to the beagle-board
recovery tools. I have a host computer send the overo a modified
version of x-loader which will ask the host computer for more files to
store at an address. I have the host computer send it u-boot and
uMulti (kernel and rootfs). Then I have x-loader jump to the address
of u-boot and begin execution of u-boot. U-boot runs fine and it
correctly loads the uMulti and sometimes it correctly boots all the
way to Linux and sometimes it fails with random kernel panics or
segmentation faults. If I hold down the power switch with my hand for
the first few seconds during power-up than it will almost always
correctly boot into linux, but if there is any extra noise on the
power supply than I get the kernel panics or segmentation faults. So
it seems that the uMulti is getting slightly corrupted during the
initial transfer which causes the problems.
I thought that u-boot did a check sum on uMulti. If uMulti is being
corrupted during the USB transfer by noise on the power supply, why
isn't u-boot check sum catching it??
I've attached the script I use to make uMulti, my Boot_usb.sh script,
and a few logs of it randomly failing and succeeding.
Thanks!
All the best,
Anthony
