Please let me know, whether I used it right. I enabled in config
build test modules, "make modules" and copied this modules to my
embedded device. There I just typed insmod mtd_readtest.ko
As far as I could see it just accesses /dev/mtd0. This is read only
(Xloader and HW-ECC). Can this cause this problems? How to check other
parts of Flash. Couldn't found some docu to the test modules.
What does this mean:
mtd_readtest: finished with errors
mtd_readtest: error -74 occurred
=================================================
insmod: cannot insert 'mtd_readtest.ko': Bad message
