- Hello Mr. Volper,
Are you still stuck on this issue, or did reseating the card resolve the I2C problems?

- Mike,
In our implementation, we already need to pass some reads and writes through to another FPGA on our "carrier... - 03:23 PM FPGA Development: RE: OMAP-L138 EMA_WE vs. EMA_A_RW documentation descrepancy, usage
- I don't see any technical reason why you could not use it, but it is preferable that you do not use the EMA_A_RW pin....
There seems to be a slight discrepancy in how EMA_A_RW is described vs. how it's used.
In one area of TI's docum...
