hello everyone.

 

i use jffs2 on my board with a 4M size nor flash. After boot success, it print "Write clean marker to block at 0x........."  like below about 15 times, and i found that rootfs Use come from 69% to 100%.

please read the documentation first:

https://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:jffs#troubleshooting

 

you should also figure out where this error is coming from:

physmap-flash.0: failed to claim resource 0

I have readed that document, and i cat /pro/mtd info, my flash erasesize is just 64kiB.

 

i don't  know what does "physmap-flash.0: failed to claim resource 0" mean, and what should i do to deal with it.

Error info of "physmap-flash.0: failed to claim resource 0" is printed form file /drivers/base/platform.c, i chosed "Phymap compat support" option and the value of "Physical length of flash mapping"  was 0 case this error.

 

After i set FORCE_WORD_WRITE to 1 in file /drivers/mtd/chips/cfi_cmdset_0001.c, error of "Write clean marker to block at 0x00240000 failed: -30" also disappear.

i dont know why you picked "Phymap compat support".  dont enable that option.  any problems while trying to use that are on your head to figure out/debug.
