Hi,
I compared two reference boards then found a difference.
In case of POR (JTAG_nSRST: pin15) asserted, MCIMX6DL-SDP rebooted but MCIMX6Q-SDB freezed.
I used same Linux versions for both of them.
Why POR caused such different results?
Can anyone explain me?
Hello Torus,
There are several versions of the SABRE-SDP and SABRE-SDB boards, can you please clarify, the versions of the boards that you are seeing with a different behavior? So we can review the schematics and provide the changes and this may show the different behaviors in the POR.
Hi jamesbone
Torus is DFAE in a region, so could you please follow-up this case?
Dear jamesbone,
Here are my board's revisions:
- MCIMX6Q-SDB SCH-27516 REV C4
- MCIMX6DL-SDP SCH-27417 REV C2
Please have a look. It seems same circuit around JTAG_nSRST.
Thanks.
