- Thanks for your response. As mentioned before I am trying to get data on DAC output same as ADC input. But I am not getting proper output signal as Input. From the code I can see uPP is using 75MHz for clock and in FPGA code it seems it ...

- Hi Andri,
We have not currently released an MDK that supports SysLink. Please follow instead the DSP Link Configuration steps: https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/DSP_Link_Configuration
Sorry for ... - VP 12:02 PM FPGA Development: RE: FPGA coding and programming for customized board using Mity DSP L138F
- we are using ADS5560 of the analog expansion board through FPGA. We are using CLK and Data through FPGA to connect to uPP interface of the OMAP-L138.
We are using example program from the analog expansion suite.
How can we debug/check ...

- Hi Ahmed,
Interesting. I don't believe there is a guarantee by the C standard as far as placement of memory. Each implementation may vary in the mechanics as long as the end result is a block of memory of at least the size requested. ... - Hi all,
I have a series problem with memory on ompl138, that the program.

Hello,
As I have a problem to set up the ADC with SPI interface through ARM, I found that I have to recompile kernel to support analog expansion suite from the page
