Had problems controlling my Meridian Digital Sound Processor through serial, which were fixed through updating the firmware on the TSU9600. (thanks to Lyndel McGee's suggestion.)
At the same time I attempted to update the RFX9600 but was unsuccessful. As I had solved my initial problem I left it alone.....

However for future reference I would like to know if it was something I was doing wrong....

I downloaded the files from the Philips site and followed the instructions....unfortunately it did not seem to like any of the files supplied.
being....."parts.config, rootfs-1.0.33.jffs2, sndr-1.0.33.bin and zImage-1.0.33.

Should they be loaded in any particular order.

Thanks

Roy
