- 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 ...

Do you mean the A53 console or the MCU console?

Good to hear. - 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... - JC 02:34 PM Software Development: RE: AM62Px: DeepSleep/MCU Only LPM fails to resume

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.

- 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...

Confirmed that the yocto build is still not enabling the RT config options

- 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. - 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.
- 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
