hi all,
I'm now tring to port yaffs direct to ucos ii, and I have some problems here to call help. The system halted while running the long_test function in the dtest.c.
Changes:
I had no changes with the yaffs_writechunk/_readchunk/_initnand/_eraseblock, and it's still using the emulated ramdisk way.
startblock and endblock changed in StartUp of the file yaffscfg.c and SIZE_IN_MB changed to 64MB.
Integrated with OS_ENTER_CRITICAL() and OS_EXIT_CRITICAL to the function yaffsfs_lock() and yaffsfs_unlock()
compile and make the souce codes with CONFIG_YAFFS_DIRECT in CodeWarrior of the tool ARM Development Suite.
checked with yaffs FAQ and maillist, but not found any helpful message, so please help:-)
the message printed in the console are as follows:
yaffs_startup.
yaffs mount /ram ok.
yaffs mount /boot ok.
yaffs mount /flash ok.
