08:13 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: I2C Board Support Package
Hello Mr. Volper,
Are you still stuck on this issue, or did reseating the card resolve the I2C problems?

04:02 PM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: RE: OMAP-L138 EMA_WE vs. EMA_A_RW documentation descrepancy, usage
Sure, as long as you don't want to reconfigure the FPGA at runtime, you could modify the usage assignment and forget ... Michael Williamson
03:54 PM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: RE: OMAP-L138 EMA_WE vs. EMA_A_RW documentation descrepancy, usage
Mike,
In our implementation, we already need to pass some reads and writes through to another FPGA on our "carrier...

03:23 PM MityDSP-L138 (ARM9 Based Platforms) 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.... Michael Williamson
02:52 PM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: OMAP-L138 EMA_WE vs. EMA_A_RW documentation descrepancy, usage

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...
