[ECOS] jffs2 problem

[Eigil Krogh Sørensen]

Hi

I'm writing code that uses jffs2 (for a Freescale i.MX25 board) and can't get it to work.

In RedBoot I have created at fis image with name jffs2 w.:
"fis create -l 0x1024"

 "fis list" gives:
Name              FLASH addr  Mem addr    Length      Entry point
RedBoot           0x00000000  0x00000000  0x000C0000  0x00000000
FIS directory     0x000C0000  0x000C0000  0x0003F000  0x00000000
RedBoot config    0x000FF000  0x000FF000  0x00001000  0x00000000
perfTsts          0x00100000  0x00100000  0x00040000  0x00100230
jffs2             0x00140000  0x00000000  0x00040000  0xFFFFFFFF


Then I have erased the FLASH w.:
"fis erase -f 0x00140000 -l 0x00040000"

After that in eCos "mount( "/dev/flash/fis/jffs2", "/", "jffs2" )" works OK, and on the tty it writes "Erase 0x00140000: .." when the "mount( "/dev/flash/fis/jffs2", "/", "jffs2" )" instruction is run.

But I can't create any files in "/" after that. The instruction "open( "jffs2tst", O_WRONLY|O_CREAT )" returns -1 (which originates from "jffs2_reserve_space(.)" that returnes because dirty = 0 and c->nospc_dirty_size = 264765). 



What am I doing wrong ? Is there anything I can do to solve the problem ?


Thanks in advance for any help!

Best
EISOR
