Looking at it one more time, we setup the GPDR with values from gpdr_lpm, and afterwards we setup them once again to update for KEEP_CONFIG. This can introduce a kind of spike on the GPIO (depending on how fast the system runs). So, fixed patch attached. Can you please test it once more and I will submit it properly? -- Regards, Igor. -------------- next part -------------- A non-text attachment was scrubbed...
