Hi, I am using yaffs on an ARM11MPcore processor running Linux kernel 3.4. I have found a problem (check attached) when writing/erasing and then sync (run in parallel). I am wondering if anyone is aware of this problem? root@128:/root# cat excersice-fs.sh #!/bin/sh MNT=/mnt/mtdblock2 while true; do echo "creating file" echo "robin" > $MNT/batman echo "removing file" rm $MNT/batman done root@128:/root# cat sync-fs.sh #!/bin/sh while true; do sync done root@128:/root# Best Regards, Mihai
