Thanks Jonathan -
That worked just fine - I started down that path but didn't get the right combination of packages. One of the PAM ipk's triggered about 24 additional package downloads and it installed just fine.
Also got NTP ins...

Hi Mike, thanks again for your reply.
I tried to regulate the RECONFIG_CLOCKS() to recover the board but the core hungs on the call.
I tried then to set the EMIF frequency to 100MHz with the code in my original post with

The problem you are having is that the FPGA logic is using the EMIFA clock with a PLL as the main logic clock within the FPGA fabric on the module.
The FPGA fabric is designed to run using a 100 MHz EMIFA clock. When you change the P...

Hello,
I am using the MityDSP-Pro development kit. Recentlly I find the board behaviors strangely.
I was debugging using the CCStudio 5.3, with some command to change the CPU frequency, all
go well. But as soon as I call any firmwir...

Nick,
I've just updated the wiki page with a new arm_main.cpp and cleaned up some of the instructions. The error messages have been hidden for now by removing the delete statements. We are planning on working towards tracking the AS...

Hi Michael, thanks for your reply.
I am using the MityDSP-PRO Development Kit with the Critical Link provided extention board.
For this board, I dont know which pin to write to select the TLV5610 DAC module.
