I have multiple j-core systems (sh2 compatible with extensions, nommu, 3 different kinds of boards running it here). There's an existing mmu version of j-core that's sh3 flavored but they want to redo it so it hasn't been publicly released yet, I have yet to get that to run Linux because the mmu code would need adapting, but the most recent customer projects were on the existing nommu SOC, as was last year's ASIC work via sky130. My physical sh4 boards are a Johnson Controls N40 (sh7760 chipset) and the little blue one is... sh4a I think? (It can run the same userspace, I haven't replaced that board's kernel since I got it, I think it's the type Glaubitz is using? It's mostly in case he had an issue I couldn't reproduce on different hardware, or if I spill something on my N40.) I also have a physical sh2 board on the shelf which I haven't touched in years (used to comparison test during j2 development, and then the j2 boards replaced it). I'm lazy and mostly test each new sh4 build under qemu -M r2d because it's really convenient: neither of my physical boards boot from SD card so replacing the kernel requires reflashing soldered in flash. (They'll net mount userspace but I haven't gotten either bootloader to net-boot a kernel.) I include sh4 in the my mkroot builds each toybox release, I have a ~300 line bash script that builds bootable toybox systems for a dozen-ish architectures, including building a kernel configured to run under qemu: https://github.com/landley/toybox/blob/master/scripts/mkroot.sh And I ship the resulting bootable system images, most recent release is at: https://landley.net/toybox/downloads/binaries/mkroot/0.8.9/ As described at: http://landley.net/toybox/faq.html#mkroot Various people in Japan have more hardware, but I haven't made it physically back there since 2020. (My residency card expired during the pandemic.) Rob
