Urukul front panel LED is red

BoluFeng

Hi,

I was tying to make the Urukul to generate some test signals. However it seems nothing was outputted. The red LED near each channel is on, according to the introduction on website, this means DDS sychronization/PLL error or software-controlled function. It would be appreciated if someone can offer me suggestions to solve this problem.

Alternatively, this can also mean that you didn't initialize the CPLD (chX.cpld.init()) or the channels (chX.init()), or even that the onboard CPLD wasn't flashed. For the latter case, you can find the latest image here and flashing instructions in the repo's readme.
