Hello,
I have a DM800 wich hangs on HD channels after max. 15 minutes.
I`m now testing with DMM experimental image 02 juli, but had the same experiences with DMM latest release.
After changing the bootargs and enabled the bootargs It was possible to made a serial log.
The bootargs I used:
root=/dev/mtdblock3 rootfstype=jffs2 rw console=ttyS0,115200n8
Here is de serial output:
