Luke is too modest. Something in the region of 5 million chips containing his hobby CPU have shipped since launch on August 8, 2024.

Are we talking about rp2350 ? Because the rp2350 can be config as pure arm soc.
In fact, if we are talking about successfull riscv soc, RISC-V esp32 may have better chance
Could you share a link or more details? What is this hobby CPU project?
I think the GP is talking about the Hazard3 [1] core. This is one of the CPU cores besides the ARM M33 instantiated on the RP2350 µC [2]. See this article from Luke Wren (Wren6991) back when the RP2350 came out [3].

What I find interesting is that RP2350 is designed as "one or the other", no way to use ARM and RISC-V concurrently, and has fuses that can kill ARM M33 cores outright.
Makes me wonder if an "ARM cores fused off, RISC-V only, no ARM fees" SKU is possible.

Thank you!
Luke Wren works at Raspberry Pi and designed the Hazard3 CPU core that is in the RP2350 chip.
