Sorry, I delete some parts of my code.
The sectors of S25FL256S flash chip has a combination of 4KB and 64KB. Only the
64KB sectors will be used, for simplicity, and the beginning address of them is
0x0002.
The "beginning" variable I use here is equal to offset plus 0x0002

Wow, that is so cool.
I may not have enough time to do the porting :-)

Could you please share your flash driver with me?
In my code, my flash is accessed via a handler defined in Xilinx BSP.
typedef struct {
rtems_jffs2_flash_control super;
XQspiPs *flash_instance;
} flash_control;
static flash_control *get_flash_control(rtems_jffs2_flash_control *super)

I use JFFS2 on Xilinx Zedboard, QSPI.
The flash I use has a hybrid combination of 4KB and 64KB sectors. I just
ignored the 4KB sectors, and use 64KB sectors only.
So, the size of block is 64KB same the size of sector in my case.
I think it may be related to my device drivers... but, I am not s
Yes, Everything is going well, if I erase the flash before use.
But, I need to store some files into flash, and reuse them when I restart my
system. I can not erase the flash every time.

I have mounted JFFS2 successfully, according to the return value.
Yes, it takes some time to do the mounting work.
But, when I downloaded a file like "test.txt" into flash via FTP and restarted
the system, error came up.

Yeah, my code is mostly like yours.
I have a handle of flash device, which can access flash hardware directly via
QSPI. So, this means, my flash can work with jffs2 without being registered
into rtems?
And, I still get these error...
[1136/1145] Linking build/arm-rtems4.11-xilinx_zynq_zedboard/
I followed the example (testsuites/fstests/jffs2_support/fs_support.c), and
some error came up, like
"undefined reference to rtems_jffs2_initialize",
"undefined reference to rtems_jffs2_compressor_zlib_compress", and
"undefined reference to rtems_jffs2_compressor_zlib_decompress"
I have no clue
Thanks for your explaination : )

Oh, I see.
I just need to treat my flash as an array, not a block device.
Thanks a lot.

Does RTEMS have the FTL(Flash Translation Layer) as Linux, that can map flash
device into block device?
How can I define the blocks used in JFFS2, according to NOR flash?
I define the segments in my flash, but have no idea how this is related to the
blocks defined in the JFFS2.
const rtems_fdi
So, what is the RFS for, basically?
