## SECTION=image
menuconfig IMAGE_JFFS2
bool
select HOST_MTD_UTILS
prompt "Generate images/root.jffs2 "
help
Build a jffs2 image of the root filesystem. This image can be stored
linearly into target's flash device at the start of the desired
partition. You should erase the whole partition first if the image
is smaller than partition's size. If not, garbage data in the remaining
space could confuse the filesystem driver.
if IMAGE_JFFS2
config IMAGE_JFFS2_BLOCKSIZE
hex
default 0x10000
prompt "Erase Block Size (bytes in HEX)"
help
Enter here the size of each (sector) block in target's flash device.
The image must use the same blocksize as the real JFFS2 filesystem
running on the target.
comment "*** add '-n' here for NAND flash ***"
config IMAGE_JFFS2_EXTRA_ARGS
string
default ""
prompt "extra arguments passed to mkfs.jffs2"
help
If needed you can add extra arguments for mkfs.jffs2 here
(e.g. --devtable=${PTXDIST_WORKSPACE}/device_table.txt,
-b to create a big endian filesystem on a little endian host or
-n if targeting NAND flash)
config IMAGE_JFFS2_SUM
bool
prompt "Generate images/root.sum.jffs2 "
help
Build an extra jffs2 image with summary information to enable
faster filesystem mount. To use this the JFFS2_SUMMARY option
must be enabled in target kernel.
config IMAGE_JFFS2_SUM_EXTRA_ARGS
string
depends on IMAGE_JFFS2_SUM
default ""
prompt "extra arguments passed to sumtool"
help
If needed you can add extra arguments for sumtool here
