+Al_Nafuur Posted September 15, 2023 Author Share Posted September 15, 2023 Setting up the Raspberry Pi development environment: Download Raspberry 32bit PiOS (here alternatively 64bit?) Install it to an SD Connect the Raspberry Pi to your breadboard (HowTo) Boot the Pi On a Pi3 I recommend resizing the 100MB swap file to at least 1GB (HowTo) Added to "/boot/cmdline.txt" as root: isolcpus=domain,managed_irq,2,3 If you like to make changes to the code, install any code editor/IDE you like (Install VS Code HowTo). Clone the Stella fork and switch to the dev branch. Open the LXTerminal and type: cd /path/to/your-git-dir/ git clone https://github.com/Al-Nafuur/stella.git cd stella git checkout feature/cartridgeportThread Install SDL2 dev. Open the LXTerminal and type: sudo apt-get update sudo apt-get install libsdl2-dev If your are using a Raspberry Pi3B+ you have to change the peripheral base address (define of PI_PERI_BASE) in "stella/src/emucore/CartPort.cxx" line 30-34 Build Stella. Open the LXTerminal and type: cd /path/to/your-git-dir/stella ./configure --host=rtstella && make -j2 all current build needs root rights to access GPIO and timer hardware directly building and linking takes about 1 hour Download this file to your ROMs dir: CartridgePort.bin Start Stella. Open the LXTerminal and type: cd /path/to/your-git-dir/stella sudo export SDL_AUDIODRIVER=alsa echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor sudo echo -1 > /proc/sys/kernel/sched_rt_runtime_us sudo ./stella -plr.timemachine 0 -dev.timemachine 0 /path/to/your-ROM-dir/CartridgePort.bin The rtstella build needs to be started without nice and timemachine disabled, also the file selector doesn't worked so you have to load the bin file at startup Before you insert or remove a cartridge from the port unplug the 5V wire from the breadboard and reattach it when the cart is plugged in. After you have plugged in the 5V you can start the cart by selecting the bin file in the Stella file selector. 2 Link to comment https://forums.atariage.com/topic/354887-setting-up-the-unnamed-1970s-console/#findComment-5317255 Share on other sites More sharing options...
JetSetIlly Posted September 16, 2023 Share Posted September 16, 2023 This is probably a very dumb question but I assume the "2600 Cartridge Port" is literally just a port cannibalized from a real 2600, or am I mistaken? Which model of 2600 is the most suitable donor / easiest to remove? Or are they all the same. 1 Link to comment https://forums.atariage.com/topic/354887-setting-up-the-unnamed-1970s-console/#findComment-5317725 Share on other sites More sharing options...

It looks like the 4 has some changes to the GPIO handling, so indeed the code may has to be adapted to the 4. 1 Link to comment https://forums.atariage.com/topic/354887-setting-up-the-unnamed-1970s-console/#findComment-5317928 Share on other sites More sharing options...

radventure Posted September 20, 2023 Share Posted September 20, 2023 I have a new Pi 3b+ on order, along with a couple of Sullins EBC12DCWN cart connectors.... hope they're the ones! A pair of SN74LVC245AN .... and I'm *partially* blaming @Thomas Jentzsch for me now also ordering PCBs and the items in the BOM, needed for a pair of Stelladaptors. Those enclosures are cheap enough, but the shipping isn't! Might be heat-shrink wrapped by the looks of it.

radventure Posted September 20, 2023 Share Posted September 20, 2023 Apologies Thomas, I incorrectly recalled who mentioned it. I should be holding @Al_Nafuur partially responsible for me ordering more stuff (all good of course 🙂, exciting stuff). The Stelladaptor was mentioned some posts back and my brain tends to associate the phrase "Stella" with you automatically. 1 Link to comment https://forums.atariage.com/topic/354887-setting-up-the-unnamed-1970s-console/#findComment-5319902 Share on other sites More sharing options...

Something like that can be quite useful when debugging. Does it have 100Mhz resolution on all channels simultaneously? Can you send some screenshots oft the analyzer captures?

I just need to configure it to the current setup. But then we should be able to see what goes wrong timing wise, in case we suspect it has to do with bus timing.

The rtstella scheduling code seems to be stable and work as it should, and you have an ifdef in your timing code that checks for rtstella, so people can try both variants. Anyway, rtstella is the way forward, the normal scheduler will never work at full speed with a real cart..
