Hi
There is a board which doesn't proceed boot procedure correctly.
Customer are using Isolation when changing the pad settings of AM5726.
To do Isolation / DeIsolation, they implement the sequences which are described at AM572xTechnicalReferenceManuel (18.4.6.1.7 Isolation Requirements).
The problem is, the bit corresponding to above step 7 does not change to 0.
Q#1: Could you let me know why the status of ISOCLK_STATUS doesn't change to 0 at STEP7?
What should we check to solve it?
Q#2:
I think that ISOCLK_STATUS of PRM_IO_PMCTRL [1] refers to ISOCLKOUT of Daisy-Chain of the following I / O.
Therefore, I guess the reason why the status of ISOCLK_STATUS doesn't change to 0 at STEP7, is because there is something wrong with the loop.
(Since this is only happened with a specific board and not with all. Therefore, I doubt that a specific device has gone wrong.)
How do you think about the above guess ?
Thanks and Best regards,
HaTa
