The TS-7552 is a new product and software support is still in development and
most of the latest files and utilities are not even available from their FTP
site. I was one of the first (if not the first!) to buy the TS-7552. Hardware
wise, it's a very good match for our application. I've been struggling to make
CAN work. Be sure to get the latest FPGA core and canctl utility. If you are
booting from the fastboot script from SD card, the kernel used doesn't have
user IRQs enable. You need to get the latest version from TS because you won't
find it on their FTP site and must update the kernel on the SD card. However,
the IRQ's on the stock kernel on the onboard flash should work.
