Hello, iCESugar's clock is driven by iCELink's PA8, and the default should be 12MHz. How do you measure the 6MHz clock currently, with a logic analyzer or an oscilloscope?
Hi,
Thanks for your reply. I just made a measurement with logic analyzer on the jumper J1.
The clock is correct. I will need to double check my code. Closing this issue for now.
I have just noticed that the ICE_CLK for my iceSugar v1.5 board is set at 6MHz. However the schematics indicate that the oscillator X1 is a 12MHz oscillator.
The only thing I can see that can divide the cock is the icelink.
I have tried with the iceprog tool as well to set the mco, but no luck.
Can someone confirm this?
