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 for yourself! 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): https://bugzilla.ecoscentric.com/show_bug.cgi?id=1000761 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. https://docs.google.com/file/d/0Bw6cJNSOahkWVngzRmRnOThyTDg/edit?usp=sharing Best regards Max Seidenstuecker -- View this message in context: http://sourceware-org.1504.n7.nabble.com/JFFS2-updated-to-support-writebuffer-tp241667.html Sent from the Sourceware - ecos-patches mailing list archive at Nabble.com.
