Just to verify, did you test with the entire series applied? (especially the PLL1 clk application changes) You may try dropping the highest operating point, it's probably overly optimistic for Orange Pi One. Is the power supply/cable you're using hard enough? Where during the boot process does it lock up? regards, Ondrej > Thanks >=20 > Michal >=20 --UIjXKnMQVJlaerLMBopDrn1XxRO84foNp-- --WCfN97K6TgtqITcaxKEelb9TlCU7FWwf2 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJXdSp6AAoJEG5kJsZ3z+/xlZsQAJiZXRC8hXWVq+Ybx3KxnASM HfPr63/Iyl7azcxLydNccHLgh1gVQq9rG41/S3rzUrWZ9xvmCXkq3Mzv7v6pHvQJ q8WxBHcvTj9ubOO4rWiLtWa6q71ROt3A3gm9oA7rVBuX1Lsn6Dtj14xI573vPjAO TyIB5iqj6MCNG4MD19Od4iNdFFg0gGPh353CZRHMeOxmGOj9kqsC0z1EsdOpGfyw MkLXyttaY3+YKJDHTqwBZwOSqAKk9lXXkTkhTiiImDmBVKByt+3Ts962TwTO3IcT WZv69E71Mb9ugkRhIs2YjOW92LYON9NKbIFKiVVQlQUBOVqEPG1MTYA1nFcu3CMb aUN2hQSfSu3GzPj0vQ8wE6KX7FkdEnNyCthrZKVHNheuxzMQIUm4J6kdIUCRehj6 VhRoKmtAzPSMOaxzEz2AB4K1DmCLYkIHOFPuFx+cGHkgkbjB7H1kVUrO4Bggfsra d4J7jE4gH71H7NH1hJgvFcDC7a2u/ugAELnN+EAWHOpqVNtDP0ndhptLPAfGEfzW rBV8VKd/dA/yD3zkVcwN2p4+XH2sgwjIGFMjOrqIPQdpFmXBIuv879mlcSJjf9aj /4nPk7KDpBnBRpKkd3fFED7yegrGprFz/ZXBEZaEV7KpBCkwrYkN/kbfTMRaAlkV iiD9eLHUB3NVq4nI/91K =KU7z -----END PGP SIGNATURE----- --WCfN97K6TgtqITcaxKEelb9TlCU7FWwf2--
