[uClinux-dev] Problems with 2GB FAT16 SD/CF cards - resolved

[Wolfgang Mües]

Hello,

DSLINUX (www.dslinux.org) is using mostly SD cards for file system 
storage. With the advent of 2 GByte SD cards with FAT16 and 32KByte 
clustersize, many user have reported problems (data aborts while 
traversing directories).

I have found that busybox needs more stack space to fix this problem.
This was a hard-to-nail-down error, because with directory traversal 
problems, network scripts fail, gdbserver fails, etc.

Patch appended.

Wolfgang
