SPI 1.3 TFT has no reset

I’m trying to patch mirroring HDMI onto the TFT, so I can monitor booting etc on a pi zero. However, all the previous st7789 driver examples have all had a reset pin assigned - but there isn’t one on this display. Any clues on how to side-step this?

Could you please post a link to the display your using.

Ok, I thought it might be that one, had to confirm it though. I think this is one of those, wasn’t designed with that purpose in mind, deals.
It looks like its doable with this one
Adafruit Mini PiTFT 1.3" - 240x240 TFT Add-on for Raspberry Pi – Pimoroni
Might even be doable with what you have with the adafruit tutorial.

Thanks @alphanumeric, I’ll try that and report back.

All good, thanks!

Fortunately the Adafruit TFT also doesn’t use a reset line. It required the kernel downgrade that is described in ‘Kernel Module Troubleshooting’, to kernel release 20201126. To save time, anyone following me would be advised to do the downgrade step first, as you need to do the install again after that step. 😀

I’ve been tempted to try that, with that display. Just never found my round 2it. ;)
You may find that doing a sudo apt update && sudo apt upgrade -y breaks it.
