I asked for TI tech support about this, but no reply.

That would help me know when we've fixed it.... - YL 06:16 AM FPGA Development: RE: What‘s the configuration mode of the FPGA？

FPGA's pin CCLK is the configuration clock , but it has two modes , namely Continuous data loading and Non-continuous data loading.
Maybe you choose the later one, right?

I still have a question. I found out in the MityDSP-L138F Carrier Board Design Guide that you connected the pin EMA_WE/GP3[11] of L138 to CCLK pin of FPGA. But the FPGA configuration document suggests DSP's CLOCK pin conn... - GG 05:12 PM Software Development: RE: Using RMII with MityDSPL138 and L138F.

The input clock on the L138 is indeed 24MHz. The max CPU speed on the L138F is actually 456MHz.
I will have the marketing folk look into correcting the table in the overview document.
sorry for any confusion.
cheers
/Tim - Hello,
How fast is the input clock of the omapl138 on the MityDSP-L138F?
Due to the MityDSP family overview, where the CPU speed is given with 450MHz, I assume a 25MHz input clock (instead of a 24MHz one on TIs EVM-Board).
Is this c...
