I can confirm that I am using @Joao_Manoel’s 5.7 kernel with my custom image based on the clockwork OS 0.5, and the suspend function works.
These were the instructions @Joao_Manoel provided for me that allowed me to have wifi working:
You will just need to know how to make the kernel, which is also provided as very simple and easy to follow instructions in @Joao_Manoel’s github pages.
The only downside with the custom 5.7 kernel is that some standalone emulator, such as gpsp and fceux end up running extremely “stuttery”. This isn’t too much of an issue however, since they run perfectly in Retroarch; something that suits this custom image very well!
