07:07 AM FPGA Development: RE: 372 MHz
Hi Rob,
In general, running at different EMIFA bus rates should be OK as long as you keep in mind the following po...

04:51 PM FPGA Development: 372 MHz
Hello,
I am running my L138 CPU at 372 MHz, which results in the EMIFA bus running at 93MHz instead of 100 MHZ.

03:38 PM Software Development: RE: Using the EMIFA to read/write FPGA registers
It worked! I changed to 0x40 and used 16 bit numbers. Here's the new code that worked-

02:09 PM Software Development: RE: Using the EMIFA to read/write FPGA registers
I tried to use the following code to write and read from a register. I used both CS4 and CS5 (0x64000000 and 0x660000... Marc Lichtman
12:19 PM Software Development: RE: Using the EMIFA to read/write FPGA registers
Well the wiki says CS5 is used for the DSP, but when I look at the VHDL it says CS4. Marc Lichtman
12:15 PM Software Development: RE: Using the EMIFA to read/write FPGA registers
Marc,
Are you using CS4 or CS5?
0x66000000 corresponds to CS5.

@sfh_OMAP-L138 -erase -p COM7@ worked!! Craig Meyers
03:00 PM Software Development: RE: continual reboot
Should. You'll need to reflash again the u-Boot and UBL. Give it a try. (good catch, BTW).
