С помощью JLINK читаю регистры на рабочем процессоре и на этом. На обоих GPIO_BT_SEL = 1! Но рабочий грузится с SD карты, а второй нет.&nbsp;</P><P></P><P>This is surprising! With JLINK I read registers on the worker processor and on it. On both GPIO_BT_SEL = 1! But the worker is loaded from the SD card, and the second is not.</P></BODY></HTML> Fri, 06 Dec 2019 09:34:37 GMT https://community.nxp.com/t5/i-MX-Processors/iMX51-and-boot/m-p/1015508#M150274 allians-spb 2019-12-06T09:34:37Z
