As I understand it the RPi 5 has differences that mean software that uses GPIO like PiDP8I (Based on SIMH) won't work without changes and requires an RPi 4. I did read this somewhere but I haven't been able to find it again, which is annoying.Aeberbach wrote: 30 Apr 2024 23:10 I'd like to make photos... I have a Raspberry Pi 5. I have followed the pidp11 instructions on making a 64-bit system work and the GPIOs are the same so it should be fine.

After following all the instructions and applying all the code patches everything seems to be fine but then the Pi simply starts and shuts itself down immediately.
I want the Pi in the pidp11 to be available for other things too, like pihole and pico development... don't really want to revert to the 4, though it would certainly be easier. I have not been impressed with the 5 at all apart from its speed! Will try again when I have another 30 minutes to waste.
:lol: Yes, I probably did read it on here, but I have seen it elsewhere too.stephen_usher wrote: 01 May 2024 10:51 Oh yes, the GPIO side has more latency than the Pi4... just check out the PiStorm threads on here for that info.
The Pi5 seems more suited to a "desktop" programming environment than a hard-core, high speed hardware interface scenario. Architecturally the Pi4 and Pi5 are very different.
Well, they've moved all the I/O into a dedicated controller, so there's probably more latency there. It also is accessed by a different library than the only commonly used, which causes problems for a lot of software.rubber_jonnie wrote: 01 May 2024 11:02:lol: Yes, I probably did read it on here, but I have seen it elsewhere too.stephen_usher wrote: 01 May 2024 10:51 Oh yes, the GPIO side has more latency than the Pi4... just check out the PiStorm threads on here for that info.

I kind of feel that maybe the RPi 5 is more of a cheap computer than a core for building projects around.
Yeah, may be the reason for latency, and I'd read that people were having library issues too.stephen_usher wrote: 01 May 2024 11:06Well, they've moved all the I/O into a dedicated controller, so there's probably more latency there.
