[ECOS] JFFS2 problems

[Stéphane Royo]

Hi everybody,

I ported JFFS2 package on my board and i have two problems. The first
concerns the last umount of jffs2_1 test (umount("/")), it always returns
the following error :

Ino #1 has use count 2
<FAIL>: umount() returned -1 Resource busy.

I didn't make any modification on jffs2_1.

I think the second problem is due to garbage collection. When i execute the
jffs2_1 about ten times the following
error appears :

<FAIL>: open() returned -1 No space left on device
ASSERT FAIL: fd.cxx[280]cyg_file* cyg_fp_get() fd out of range
ASSERT FAIL: fd.cxx              [ 280] cyg_file* cyg_fp_get()

and in same way, when i execute the jffs2_3 i have the error :

<5>jffs2_reserve_space(): Low on dirty space to GC, but it's a deletion.
Allowin
g...
FAIL: creat() returned -0000001
ASSERT FAIL: fd.cxx[280]cyg_file* cyg_fp_get() fd out of range
ASSERT FAIL: fd.cxx              [ 280] cyg_file* cyg_fp_get()
                                                             fd out of range

For information, i use the minimal configuration for JFFS2 (no kernel, no
com driver, only lib, JFFS2 package and flash driver) and the
CYGNUM_IO_FLASH_BLOCK_LENGTH_1 is equals to 256kb.

I would like to know if somebody has encountered the same problems.

Thank,
Stephane

How did you manage to compile the tests without the kernel? The second
include statement for jffs2_1.c is <pkgconf/kernel.h>?

What size flash blocks does your target use?
