Dockstar: bad block: it is save to flash uboot?
March 26, 2017 06:34PM
Hey there,

i want to flash one of my dockstar devices with newer u-boot, as described in http://forum.doozan.com/read.php?3,12381.

But demesg says it found a bad block, so i want ask if its save to flash u-boot? If not, what's the workaround?
(it's not important to preserve the original uboot or kernel)

Regards Lutz
