I added JFFS2 package into my platform. For the default configuration, it
works well.
Since I don't want to locate the JFFS2 image at a static location(set by
"CYGNUM_IO_FLASH_BLOCK_CFG_STATIC_1"), I switch to
"CYGNUM_IO_FLASH_BLOCK_CFG_FIS_1" to let "/dev/flash1" device get its block
infomation from FIS.
But when cyg_io_init() call "/dev/flash1"'s init function, all FIS
information are not intialized yet, and the device init fails.
Until Redboot's cyg_start() call _do_flash_init(), the FIS get initialized.
So the "/dev/flash1" device was not available when I mount the JFFS2
filesystem. However the mount action still pass(the mount only try to
lookup the device, but not check whether the device is available), but I
can't write any files because the "/dev/flash1"'s block infomation is
invalid(all zero).
So I wander how to get "CYGNUM_IO_FLASH_BLOCK_CFG_FIS_1" work?
