finally I got a first version running. The port is based on the JFFS2
version contained in the 3.9.2 Linux kernel and is only tested on Freescale
MPC5668G PowerPC processor using NOR-ECC flash with 8 Byte aligned write
blocks. With the quality of the code it may be considered a hack, but see
The main goal was to get the writebuffer working, which is also a big part
of the NAND portion of the code, that was out of focus and needs to be
implemented by s.o. else who has got such a flash device.
There are still some aspects that need optimzation and solid testing,
especially the garbage collection. There were some issues described in the
.cdl file with icache locking that I did not understand yet.
Freescale specific files can be obtained from this bugzilla entry (if you
have this hardware):
The updated file system is provided in a zip package. Please let me know how
to add this to the project cleanly. I am not used to mailing lists yet.
