Mounting EXT3 filesystem


Hi all
I am working on a linux based embedded system .I would like to know whether it is possible to mount an EXT3 type filesystem from a basic file system?I have a vendor provided bootloader flashed in my NAND flash which expects only JFFS2 type filesystem.I cannot modify my bootloader since i don't have the source code.I wanted to use an EXT3 filesystem located in my SD card,but my bootloader expects only JFFS2 filesystem.So is it possible to bring up a basic file system and from there to mount EXT3 filesystem present in the SD card?

Thanks & Regards
Ananth

That depends. I am assuming that the boot loader flashed into the NAND is some kind of kernel or is it just a loader that loads a kernel located on the flash. If its just a loader and then from there you load a kernel then you could make a small boot area on the flash card that is formatted in JFFS2 and the rest in ext3. I don't have much experience with embedded systems other then my NAS and it has a actual kernel and compressed file system image flashed onto it.

If the kernel is flashed on then it may not even support the ext3 file system.
