Mintypi Freezing Mid-Game

I recently made a minty pi with the latest version of Helder's PCB (the blue one). At first all was well but recently the system started freezing after about five minutes of use. While in-game, the sound continues to play, but the screen is frozen, and I am unable to exit the game. If left on the main menu of emulationstation, the system will also freeze. Any help would be welcome.

Try SSHing into it (there is a guide here: http://www.instructables.com/id/Use-ssh ... pberry-Pi/ -- you can skip the part about enabling ssh), and editing the file /etc/modprobe.d/fbtft.conf. Change the "speed=" bit to "speed=60000000" and see if that clears it up.

I tried that, but the problem didn't go away. The sound continues to play, but if I press the start and select buttons to try and exit the game, the sound continues to play. This makes me think that the problem isn't related the screen itself but rather something in emulation station that's making the game crash. It typically happens more often when I'm playing a GBA game than when I play SNES, so maybe it has to do with the demand the GBA game is putting on the system.

Thanks for the help.

Just started playing my minty pi...zelda Oracle of ages. Played for an hour. Took a break. Now in the past 20 mins the game has frozen twice, sound continues. But no buttons work at all. Have to reset it...

Was advised to lower overclock. Lowered arm freq to 950 and over voltage to 3. Seems to be okay now...but I may just remove the overclock completely.

Lowered the over voltage to 3V? Isn't it 2V by dafault?

No, you lower the over_voltage parameter, it's not the same thing
read here https://github.com/RetroPie/RetroPie-Se ... erclocking and here https://www.raspberrypi.org/documentati ... locking.md

SELF EDIT : self kick myself, you were talking about that, i have not read you correctly lol

This table describes the overvoltage settings for the various Pi models. The firmware uses Adaptive Voltage Scaling (AVS) to determine the optimum voltage to set. Note that for each integer rise in over_voltage, the voltage will be 25mV higher.
Version Default Overvoltage Setting
Pi 1 1.2V 0
Pi 2 1.2-1.3125V 0
Pi 3 1.2-1.3125V 0
Pi Zero 1.35V 6

So i should use 6 and not 3? :oops:

Yes, it's the default voltage setting for the Pi Zero as written in the official documentation. You must understand that the default value will likely void the overclocking settings as you voltage will be higher, you won't be able to go up in frequencies

If you intend to suppress overclocking, just delete all the lines in the config.txt
this will make the pi run stock frequencies
