I will read ubifs and try your test program, but it will take some time.
Just to make sure, your kernel is plain linux-2.6.27, isn't it?
And where can I get ubiattach and ubimkvol tools?
While I am not sure this is related to your problem, but mwr.c needs
fixing.
/* Now write int's to the file as if it were memory (an array of ints).
*/
for (i = 1; i <=NUMINTS; ++i) {
map[i] = 2 * i;
}
'i' must be less than NUMINTS.
I guess you want to do,
for (i = 0; i < NUMINTS; ...
