DMA channel collision on N64 games
#2
DMA is a weird thing on Raspberry Pi, sometime, for whatever reason, something decide to change DMA channel it is using... Had some troubles with this too :S

I have a build with the possibility to set RX/TX channels (this version is for fullscreen) : https://drive.google.com/file/d/1o4K8Jit...sp=sharing

I did compile it a while ago, I hope it will work.
With this version, arguments need to be set as followed : 'fbcp-ili9341 -DMA_TX_CHANNEL 1 -DMA_RX_CHANNEL 5'
To check for available channels, follow this link, under 'Compiling' section : https://forum.freeplaytech.com/showthread.php?tid=4989

You will need to stop (not disable) the current service that run the driver : 'sudo systemctl stop fbcpFilledNoSleep.service'

Sadly, I don't have my device with me to help more (quarantine :/)
