A customer created SBL NULLs for the AM62AxRTOS SDK c7x, operating at 500MHz and 1000MHz, based on the above.
After booting them up and using the CCS profile clock, both clock speeds appeared to be running at 850MHz.
(A 50msec sleep operation was measured at 42041576 cycles, approximately 840.83MHz.)
Q1: Does the profile clock frequency change depending on the CCS load program?
Best regards,
O.H
