    OH MAN. I worked on an Android tablet that used a rockchip CPU, not the one listed here but an older one (I think RK3026). What a PIECE OF SHIT. I don’t wish that tablet on my worst enemy. Battery life was like sub 2 hours with a 3200 mAh battery. Sometimes it would start running hot, and you could watch the batter percentage go down one percent every 10-20 seconds. The only way to break it out was to reboot it or let it die.

    We later upgraded our CPU to the 3288, one gen older than this one, and it was significantly improved, but still very entry level.

    Anything that’s turning complete, has enough ram, and has a c compiler can run Linux. Theoretically, you could program a CPLD to run brainfuck and you could still run Linux.

        Yes. Any turing complete processor can perfectly emulate any other turing complete processor, whether it is x86, arm, or riscv. Mainline Linux can then run on this emulated processor without modification.

          Damn that’s gonna be slow.

          But I guess speed was not a criterion.

          “boot” is the next important part. Have you tried reading it in full?

            Emulated processors can do the same things as physical processors, including booting from disk.

              Boot = Bootstrap

              If you’ve loaded up a virtual CPU first that’s not a boot of mainline Linux on the CPU.

              Yes, but it doesn’t count, because the SoC from the picture didn’t boot Linux, an emulated machine did.

              That’s why the records on doing this silly stuff on progressively smaller microcontroller use the word “run”. It has more transitivity.

                I’m not sure I understand your argument. Are you saying that the emulated processor executes instructions while the SoC doesn’t? Every instruction that goes to the x86 is broken down into several SoC instructions, which the SoC executes in order to emulate what an x86 would do. Saying that the emulated x86 is booting/running Linux, but the SoC is not is like saying that computers can’t run java code, they can only run jvm.

                  I’m saying it runs it because “running” is transitive, but doesn’t boot it because “booting” is not. Similarly to how you can carry your grandkid by carrying your kid who carries their kid (carrying is transitive), but you can’t give birth to your grandkid by giving birth to your kid who’d give birth to their kid (giving birth is not transitive).

    I remember this captcha. I gave up after about the fourth round. The prize just wasn’t worth it, and I wasn’t on a machine where I could try scripting out a solution.

    ARM really shot itself in the foot by making it so every SOC needs to have a custom OS image tailored to it. x86 meanwhile lets you pick a universal binary that’ll sort itself out at runtime
