The FPGA is configured using 8 bit parallel slave select mode via the EMIFA bus connection to the Omap L138 processor.

I have finally got the switch to work. The last problem was that I had set the CONF0-CONF2 bits to 0x110, which sets MAC 5 to MAC operation. I have now set it to PHY (0b101) and I can now connect to the network.
Thanks for all...

- Hello,
We are using the MityDsp-L138F board. I want to know the FPGA's configuration mode on the board, is it MASTER SPI,BPI or slave SPI ,BPI? We can find nothing about pin M0&M1 of FPGA in the datasheets.
Anybody can tell me?

- The MiniSD and MicroSD standards are both electrically identical with the same interface, only the physical size is different. So either should work just fine.

We are in the process of using Micro SD card on our board. Does the Linux driver for SD card on MityArm supports Mini SD card as well?
