Dear developers,
unfortunately, it seems, we need CompactFlash interface in our device for compatibility with old device :-(
Can we connect Stamp9G20 to the schematic shown on Figure 20-5 from AT91SAM9G20 datasheet (page 148)?
Can you, please recommend something how to implement support in Linux kernel for CompactFlash?
Do you have some benchmarks related to CompactFlash vs SD card on AT91 CPUs?
Best regards!

Re: Stamp9G20 and CompactFlash
You can connect the CF like in the diagram in the AT91SAM9G20 datasheet. Please keep in mind, that the memory bus is only 1.8V, so driver chips will be eventually needed.
For Linux support, have a look at this thread from the arm-kernel mailing list:
http://thread.gmane.org/gmane.linux.ports.arm.kernel/61826/focus=61827
It's all pretty new and some kernel work has to be done.
We have no benchmarks, sorry.
