<br>
I wonder if this is target specific now, if i literately use the
sources you posted i get an error '-1' returned from the
rtems_mkdir().<br>
<br>
The only change i made was to malloc a smaller chuck, 32k. Of
course my malloc() is operating of the same SRAM chip, but it was
in a different address range.<br>
<br>
Not sure what to do now, i guess i have to work out whats up with
RFS on ARM thumb. Does anyone know what platforms RFS was
tested/developed on ?<br>
<br>
<br>
</blockquote>
These are tested by the fstests set of tests. I don't believe these
were in the 4.10<br>
tree. Now these are tested on every target that has the testsuite
run. This would<br>
primarily be i386, SPARC, MIPS, PowerPC, Coldfire and ARM. That's
where most<br>
of the daily developer activity is.<br>
<br>
The code was initially developed and tested primarily on Coldfire,
SPARC, and i386.<br>
<br>
Chris can say more about it specifically.<br>
<br>
I would suggest that it would be good to see if this fails on 4.11
if you haven't<br>
already.<br>

Alas the mkdir() is the first
filesystem operation i am doing. I
am not sure if i can send
attachments to the list so i've cut
and pasted the relivant functions
below. I guess the following would
run on any BSP, its just a 256k
block of sram. If there is a BSP
with enough memory the base pointer
for the filesystem could just be a
big malloc().<br>

Is this reproducible with
something you can share?<br>

Looking at the source, I think
this case is that you<br>
filled the filesystem and there
were no free blocks.<br>
But I am looking at the head and
not that familiar<br>

Hi,<br>
<br>
I have an RFS filesystem
using the nvram device, its
formatted ok and
mount_and_make_target_path()
also worked ok. But
attempting to mkdir() causes
a really lowlevel issue.<br>
<br>
The callstack;<br>
<br>
rtems_rfs_block_map_find()
at rtems-rfs-block.c:246
0x81198bd8<br>
rtems_rfs_block_map_next_block()

rtems_rfs_rtems_eval_for_make() at rtems-rfs-rtems.c:440 0x8118e142<br>
IMFS_evaluate_for_make() at
imfs_eval.c:435 0x81190718<br>
mknod() at mknod.c:64
0x81183d5c<br>
mkdir() at mkdir.c:29
0x81183cf0<br>
build() at rtems_mkdir.c:101
0x811843a0<br>
rtems_mkdir() at
rtems_mkdir.c:136 0x811843a0<br>
<br>
<br>
the
rtems_rfs_block_pos_block_past_end
macro is failing and causing
the return of ENXIO.<br>
<br>
The two arguments to the
macro are;<br>
<br>
bpos->bno = 1<br>
bpos->boff = 0<br>
bpos->block = 0<br>
<br>
map->size->count = 1<br>
map->size->offset = 0<br>
<br>
Which seems to me the cause
of ENXIO being returned, but
i dont know how my BSP could
affect this.<br>
<br>
Do people use RFS in
production systems ? i am
using the 4.10.2 sources.<br>
<br>
<br>
