Redboot _do_flash_init() too late for initialization of "/dev/flash1"?


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?
