For Koelsch, this simply meant I reverted Geert's clocks-off patch. But there is a fundamental problem below: GPIO interrupts described with the "interrupts" property in DT do not get the underlying GPIO requested. And if noone else is using the GPIO block, its clock may be turned off. I have an idea how to fix it, need to check priorities of the other tasks, though. BTW, the continous EDID read test on your board is currently at >360000 successful reads, a not a single failure :) --GvXjxJ+pjyke8COw Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBAgAGBQJWVVnTAAoJEBQN5MwUoCm2QrYP/RcD/Iv8ga2J6e5rYF1WB6t3 072J3JgP4RC5rkpMURmLvAijzC0LZxlH3xo5/8JCL+7OSkm/Q6xX0NlGJEC7fG02 62LVGijL0FnjbPHw2ruUbtJXBBSzreKe7eyO9j1eRYGXAWR6pOrO/RdNG0ZjNDPj CMvt6njCfSTEigeUpLR8ZRv1unkjHpFgUaUblwl/6IphE6CgrSRR0BXhcIe0ofh6 jC3bQHP4LyNEUG9atJxqwDER0mGndIHfv5TNPLHos4EN2MopZdZBHN4tITHGmxH8 Sahfyv8hw0CP7UOM6jjPn2gFfvnELxd3VigBOX3un39sTyJJ2G23ZWB1IFhqXVtC NMPdx2B/0EVOuwZu5231pFwGmf9VqLtNJyPyB4TYpfrbctsWVZ12i8LuGXrh+JZL 2EkjtmRKzQp3/rV+Ei1QXKx6qG174wP0AnrgPGdMwAg+k5FiGUoSoYmNOAcrwb4L WuekQrSfiBfC7rgyBF/pC+xAeQs7Qukzy32sG5sUT28nE2bmwvGUJXtumng/fbsu AQEjJr4TUsBwPtdvkRuC45Jua54V3VoIvwfk/5C9NAjZ0/cTXMbc8LF537tXHtQ5 tep6M0+bryN+xNHL5q31YidyUMYDxmNIoGD6WNMk9J9z3wLp1FWUu75LEMZ7vEiI CBsjA2I2/fU6lXDZBRBY =9My7 -----END PGP SIGNATURE----- --GvXjxJ+pjyke8COw--
