J6PEVM577P: PORZ RESET not reset after the kernel started

AClemotte

Part Number: J6PEVM577P

Hi,

I've discovered that the J6 + EVM PORZ reset does not reset the board after kernel started. I'm reseting the board with the SW9 push buttom. If I press the buttom before, the board reset without problems. This behavior is strange. We're working with the TI Android SDK.

Hi Alejandro,

I don't see the issue on my setup. Using a "DRA76XP-DRA77XP-TDA2PX-ACD" EVM Rev-C.
Pressing SW9 at any point of time results in a reset.

Regards,
Vishal

I burned on the EVM the TI-SDK prebuild and I don't see the issue any more. Its looks like PORZ was disabled by a bug in our SW, is this possible?

Don't know for sure.
What kind of changes are you doing in your software?

You can look at SW9 part of schematics to get some clues.
