Hi everyone,

Just finished building my uConsole this weekend, over the moon with how it has all come together (finally). Maybe it’s old news, but I noticed in htop that there are only 4 cores running on the A06 version. This appears to be the same as the devterm out of the box config. Presumably it’s for power/thermal management, I was surprised but seems like it’s already been documented. On this basis I’d recommend the CM4 version for anyone who’s trying to decide, the RK3399 is a nice chip, but without 2 cores running (haven’t tried turning them on, but for sure it’s going to hit the battery life) there’s no reason not to go for the CM4 version. I might put in an order for the adapter plate soonish.

Link to the devterm thread.

> I just have my second-hand DevTerm A06, and I found in htop, only four cores are running. I used lscpu and found there are 2 offline CPU 4 and 5, and I can manually open it by chcpu -e 4,5. I am wondering why these CPU are disabled by default. I have installed clean ClockworkOS v0.2, so it is not the configuation for its first owner that causes this situation. Or if the CPU is managed by some tools of DevTerm ? If some conditions are met, the manager will automatically close/open CPU ?

Also the wifi on the A06 (and presumably the RISC-V too) does suck (until you hack it), but still otherwise, great job clockwork pi 10/10! 😃

You’re missing the gearbox command structure. From the github:
