I ran into the RP2350 chip this morning. The Raspberry Pi Pico 2 board has this chip and the fun part is - - This chip has dual ARM M33 and Dual RISC-V cores on it. - Architecture can be selected at boot time! I was like.... what? One board to learn firmware engineering on ARM and RISC-V architecture? What can be better than this. Invest in one board and learn two architecture! It doesn't stop there, it is a dual core solution for each architecture, so we learn multi core programming. To top this further, M33 is an implementation of the ARMv8M architecture with security extension. This means, we get to dive into the latest v8M architecture and fiddle with the security feature (formally called TrustZone). I plan on including this in the Library Access. To begin with, we'll explore this in the Tech-Syncs. In a month or so I'll introduce courses based on RP2350 chip. It is going to be so much fun. I want Pyjamabrah Library to be the only place on the planet to learn everything about low level engineering as the industry and professionals use it.
