Re: [Yaffs] problems with yaffs direct on ucos ii

I dont know if this problem is due to the malloc in the direct interface, and I am tring to working on it.

Is there someone having the same problem using malloc() and free() in ADS?

Any ideas are welcome, thanks!

主题：problems with yaffs direct on ucos ii

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.
