by the way, vfat support is compiled-in in omap4 kernel. |
SRU Justification:
Impact: Removing the running kernel (perhaps because we want to rollback to a previous one due to a regression) result in a system with no support for fat filesystem, and thus with the inability to flash/ the alternative kernel in the boot partition
How to reproduce: boot the panda board, remove the running kernel and then run flash-kernel (see below)
Fix: Compile in support for v/fat and necessary nls modules (codepage 437 and iso8859-1) (see the attached patch)
