Diving into the bare-metal boot sequence of #WebAssembly on the #RP2350 reveals the critical handover from the hardware reset trampoline directly into the #Rust #embedded runtime. Before the #embeddedwasm engine can even spin up, the runtime executes this precise initialization block to systematically unlock the hardware spinlocks by writing a 1 to the SIO registers starting at 0xd0000100. In multi-core microcontrollers like the RP2350, spinlocks act as essential hardware synchronization primitives that prevent both cores from accessing the same shared data simultaneously; when one core claims a lock, the other must continuously check, or spin, in a loop until it is released. By writing to these registers to force-clear them during boot, the system guarantees a completely clean slate and prevents immediate deadlocks before executing any WebAssembly payloads. #ReverseEngineering

Lilbits: Samsung Galaxy Z Fold 8 Wide, Razer Blade 16, and more fallout from Chuwi’s processor mixup

Two recent laptops from Chinese PC maker Chuwi that were supposed to ship with AMD Ryzen 5 7430U processors actually had Ryzen 5 5500U chips inside. That means instead of getting a processor with a Zen 3 CPU, customers were getting notebooks with chips featuring AMD’s older Zen 2 architecture.

But the only way to prove this was to actually open up the computer and remove the CPU cooler to look […]

Pondering what is the easiest way to get enough PIO driven GPIO to watch a 16-bit address, 8-bit data bus.

So, def RP2350 (esp as 5V tolerant), but maybe one of those Pimoroni "XL" Pico things, or maybe a PGA2350 or Pico Stamp, or something like that...

Anyone any experiences of these larger Pico-like things (or know of any others)?

ATABoy Is An Open Source USB Bridge For Old IDE Drives

You can get an IDE to USB bridge from all the usual sources, but you may find those fail on the older drives in your collection– apparently they require drives using logical block addressing,…

I wonder if anybody has yet made a flexible #S100 emulation card comparable to the #UniBone and #QBone cards for DEC systems? Recent projects like #BlueSCSI, #OneROM, #PicoIDE, etc. make me wonder whether an #RP2040 or #RP2350 might have the horsepower to do the job?
