would have been considering it for sure if I was going to go totally bare
metal. Wasn't sure how well it would mix with RTEMS or another RTOS but if
it is known to work reasonably well, then "problem solved" as far as I'm
concerned. Those write speeds you mention (even worst case) should be good
enough for me.

For CAN bus do you use a driver that goes into the BSP or is all of the
code in application-space?
I have an STM32F4 Discovery board on hand and got the BSP built and Hello
demo to run, so now I'm interested in making the jump to doing something
useful.. same with Zynq actually.
