If some were out of range, the monitor would show an error message, but with the PLL problem, the monitor does not appear to detect even an out-of-range signal. I'd guess the PLL itself cannot handle the parameters. The largest working ref_div_max limit is 131. with 131: 162000 - 161990, pll dividers - fb: 1425.4 ref: 21, post 6 with 132: 162000 - 162000, pll dividers - fb: 1493.3 ref: 22, post 6 avivo_reduce_ratio does not change these values. -- You are receiving this mail because: You are watching the assignee of the bug.
