  1. 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 […]

  2. @rpimag I did a bit more work on my UART booting Flashless Picos. On the end of each "pico" there's an I2C port for the I/O expander (used to reset/setup the RP2350A to boot from UART) and a UART port to send the bin file/communicate after boot. The Pico2 in the PicoUART6 is running CircuitPython using Adafruit_CircuitPython_PIO_UART for the non-hardware UARTs.

  3. Many people wanted a RESET button on their Pico but I decided to make one without buttons 🤣 .

    It currently has no FLASH/PSRAM and boots over UART (3-pin at the bottom) or you can upload a UF2 over USB. The I2C expander towards the bottom (4-pin STEMMA QT) can twiddle the BOOTSEL, SD1 and RUN pins.

  4. I've hacked together a CircuitPython library to UART boot the RP2350. The two bin files it's uploading just cycle through the LEDs in different directions.

    I still have no RUN pin so I'm using one of my USB Power Switches to power cycle the board.

  5. The RP2350A is feeling a bit more real today as I have cut tape in my hands (from #LCSC). Now I just need to find the board I designed for them back in September 😆 .
