MW 02:42 PM FPGA Development: RE: FPGA Done led not turning on with CPU programming

How are you generating the bin file?
Check this "wiki page":https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/FPGA_Overview. At the bottom there is a command for generation.

Hi,
We have made our own customized board uing the Industrial IO Board and the Analog expansion board.
We were programming the FPGA (x16) using the JTAG programmer. We used to have the Done LED turned ON once the programming was done... Vivek Ponnani

We are developing a new codec using the MityDSP. So the Industrial IO has the DSD1791 audio DAC on it's McASP. This DAC uses the TX clock generation module (ACLKX and AFSX) for the bit and word clock. The other L138 EVMs also uses... Tom Riddle
