[U-Boot] Possible uboot crashes

[John Tobias]

Hello Guys,

I would like to know what are the possible chances that u-boot/ubl crashes?.
I am looking for some theory/scenario that I can possibly connect/apply the
scenario to what happened to my device based on dm6446.

The device has been running for a year now and for some reason it never come
back anymore. I connect through the serial port of the device and check if
there's something different. The device was in the state where the
bootloader is missing. I re-program the u-boot and the device boot it again
as I expected.
The /dev/mtd0 and /dev/mtd1 are not writable on linux space in order to
screwed up the uboot.

Thanks,

John
