Hacking the HDO1k/HDO4k Rigol 12 bit scope
Randy222:
For the 1k-4k
Anyone have the chipset device name that is used by the pwm_fan.ko driver?

Is DHO1000 actually locked down by TrustZone of RK3399 ?
If not, we can actually re-write the whole application in Open Source (GPL) license to replace the whole Rigol ones

I don't see any indication of locking down. However, rewriting the application will take a serious amount of time and development skill (including but not only reverse engineering). It would be nice if we can gather some effort to improve the official firmware by making some mods (for example, make the LXI binary readout faster so the scope can work better as a digitizer), but a major rewrite by community doesn't seem practical to me.

Most readers here are probably following that other thread anyway, but just for awareness: There has been some nice progress modifying the DHO800 software on the GUI level, and some early work digging deeper into the Android system, even trying to replace it with "plain" Linux. Have a look at the most recent page or two of posts if you have not followed this:
