Hi. Please CC the list.
 
I haven't used mkyaffs2image, although there is a binary included in the 
MontaVisa bundle NFS filesystem which might be useful. The program would need 
to know the DM355 ECC algorithm and layout so I would expect a version you 
found out on the internet to need some modification.
 
To make a YAFFS2 filesystem image I mounted and copied a few files into a 
filesystem from within linux, then dumped the raw partition to a binary file. 
Note that the OOB layout in the dump file differs between dumping from 
"nanddump" under linux, and PEEDI.
 
Eventually I will want to be able to use mkyaffs2image but - one thing at a 
time.

        Hi Jon,

         

        We are now corparating with ronetix. There is a guy who's name is Tito 
. He remote accessed to my board and upload ubl, u-boot, kernel.Tomorrow he 
will try to upload filesystem. But I have a problem. Our filesystem is now a 
reduced file sytem by busybox , it is a tarball now. I am extracting it to MTD6 
partition on nandflash , which is described on DVEVM user guide. This  guy 
(Tito) want met o convert this tarball file to bin file. Did you achive to do 
this? I just googled and find a utility which is "mkyaffs2image.c" ,i builded 
it , but it didn't work. Did you use that utility?

         

        Best Regards

        Hi Canibek,

         

        I can upload ubl, u-boot, environment, kernel - everything but the 
filesystem using PEEDI. However the current firmware version for PEEDI does not 
program DM355 NAND flash correctly. The older firmware version I have programs 
binaries but not YAFFS filesystems correctly.

         

        We have been in touch with Ronetix who are keen to help fix the 
firmware, we are going to send them one of our boards to develop on.

         

        At the moment I am programming a binary ramdisk image which I can boot 
from enough to run my in-house linux-based firmware update routine which writes 
a YAFFS2 filesystem, then after a reboot I have a finished board. Our 
production department is now using this method to start shipping products.
