FPGA-based open source development producing real hardware capable of running Linux.
System bringup (processor, memory, serial, compiler, libc, kernel, shell prompt.)
IP issues (open licensing, patent expiration…)
Fabbing an ASIC with Kickstarter
Existing projects (jcore, RISC-V, LEON…)
Bitstream development for software developers.
Minimal hw devices needed for a new platform to get kernel up and running to shell prompt on serial console.
Kernel expectations for hardware - how to design hw to work well with Linux device/driver/resource/irq/etc. models.
Device tree hello world - minimal dt examples for real hw.
