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

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

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).

- DG 01:51 AM Software Development: RE: Can't ping by name
- Solved! Thank you!
The only disadvatage is the /etc/resolv.conf file is rewritten (by udhcpc?) on reboot.
I wonder the dns-nameserver parameter in the /etc/network/interfaces has no meaning, even for static ip configuration?
