I have been trying to get this DM355 to boot for about 2 weeks now. I have received no answers to questions, using your SD boot tool does nothing, the RR SDK refuses to build, the EVM kernel and rootfs will not boot, and I don't have a JTAG so I do not feel safe flashing U-Boot, which may be the issue since the version that came in flash memory is about 4 years old and lacks support for most things useful.So how do I get my money back for this expensive paperweight?At least with a GumStix board I can get some help.
try mini2440 is cheaper and better, and you should stick with opensource for future products, leopard board is not open source.
