Stuck on Calibrating delay loop... with Device Tree enabled #29

Closed ponyatov closed 5 years ago

ponyatov commented 5 years ago

After switching to device tree build (need some custom boards support with difference GPIO connections), got this error: system stops boot on calibrating delay loop. Most googling gives similar results for other boards: errors in system timer code/dts, goes to halt on delay loop.
