JC 02:07 PM Software Development: RE: AM62Px: DeepSleep/MCU Only LPM fails to resume: Thanks Connor for the update. Jonathan Cormier

CL 12:36 AM Software Development: RE: AM62Px: DeepSleep/MCU Only LPM fails to resume: Hi Jonathan, it turns out the MCU console was freezing on suspend due to the device manager R5F isolating the I/O pads from the MCU UART peripheral. I was able to bypass this with a custom pinmux in the MCU R5F firmware. I've attached a ... Connor Larmer

Do you mean the A53 console or the MCU console?

Good to hear. Jonathan Cormier
CL 05:10 PM Software Development: RE: AM62Px: DeepSleep/MCU Only LPM fails to resume: Hi Jonathan,
After removing the resistors, Deepsleep is functioning now. As for MCU only mode, we have been able to trigger a system resume through the example R5F IPC firmware, however the debug console still becomes unresponsive unt... Connor Larmer

Hi Connor, were you able to test just Deepsleep mode?
When we were trying this, I don't think we tested MCU only mode but TI presumably supports it. I will see if I can reproduce your results.

CL 11:07 PM Software Development: AM62Px: DeepSleep/MCU Only LPM fails to resume: Hello,
We have a Critical Link development board with an AM62Px SOM (4GB). Currently, we are attempting to validate suspend/resume functionality in DeepSleep and MCU only modes.
Our procedure is as follows, using the prebuilt SDK 1... Connor Larmer

JC 05:37 PM Software Development: RE: realtime linux on am62x: > Still working on the yocto recipe part. It built but the kernel was missing the RT configs. Probably missing something simple.
Confirmed that the yocto build is still not enabling the RT config options
Tested using processor-sdk-... Jonathan Cormier
NW 03:55 PM Software Development: RE: realtime linux on am62x: Please do.
There is a chance we won't need it, but I would like to have it my back pocket in the case that we do need it.
On the am57x family we did need the RT patch to keep up. Nathan Wright
JC 03:27 PM Software Development: RE: realtime linux on am62x: Hi Nathan, I never heard back from you so this dropped off my todo list. I can try to pick it back up next week to see what the status is. Jonathan Cormier
NW 03:18 PM Software Development: RE: realtime linux on am62x: Hi Jon,
Just checking in, we are rapidly approaching being able to know if we need this or not. I thought I would ping you and see if you made any progress on it.
Thanks,
Nathan Nathan Wright
