Some brand new great news concerning the #LEGO #SmartBrick #reverseEngineering efforts: after all the teardown that we've seen, there's already a KiCad(!) schematic. GitHub user nanash1 has shared their findings, so everybody can continue working from here!
The ASIC seems to handle quite a lot: NFC frontend, speaker, microphone, wireless charging + battery, LEDs and photo diode. Logic levels are 1.8V. The BT SoC connects 3 SPI peripherals: the ASIC, the accelerometer and the SPI flash. 🎉👏 Nice!

😃 May this produce joy for some!
#reverseengineering completed now by finding a pattern to light all six LEDs with 3 driver pins. I've put it into a drawing, together with a schematic: each driver pin is connected to four LED pins (two anodes and two cathodes). To leave an individual #LED dark, in its time slot leave one or both drivers high-Z.
They used 5V for the #microcontroller and blue LEDs, because of their forward voltage >2.5V.

They took 200µs per time slot: overall period of 1.2ms.

Hello and welcome to the #nakeddiefriday again. This one will be a continuation of the previous one with the same exhibit but in more depth. :-)

To remind you, this is the unnamed smartcard IC, which I believe was fabbed by Samsung.

Let's try removing some metal from the top. 🧵

Bueno, ya hay drivers y de todo (Que no hice yo)... lo que necesito ahora es ver como reemplazo todo esto de forma casera.

Estos SoCs hacen el siguiente boot sequence.

  • BROM carga un SPL (Secondary Program Loader / Grabador de programa secundario)
  • SPL carga la parte principal de un U-Boot, este se llama "U-Boot proper" (La razón de por que se separa en dos es por cuestiones de memoria, hay poca memoria SRAM y se necesita cargar una parte que sea el módulo encargado de gestionar la DRAM que son 32/64MB)
  • Resto de U-Boot.

    • Conceptualmente SPL carga el mismo código que U-Boot pero restringido, solo los drivers necesarios y una version recortada de esos drivers, todo para meterlo en la SRAM.

    A mi parecer, son conceptualmente equivalentes estos terminos.

    BROM = BIOS
    SPL = Bootstrap
    U-Boot = Bootloader //Este es literalmente así jajajaja, no es "equivalente" U-boot es un bootloader, solo que un bootstrap y un bootloader tienen diferencias.

    Al margen de eso, dejo estos artículos de utilidad.
