HLK W806 What is this ? Mistery very cheap and powerfull CPU ?

(1/4) > >>



C-Sky core is somewhat annoying with tool support.

And it looks like QFN56 version is available cheap, but it does not have any wireless support, and QFN32 has wireless, but not available. And dedicated wireless pins take up half the pins of the device.

It is obviously something purpose designed, and not intended as a general purpose MCU.

Do you have any info on this CPU ?

You yourself linked the datasheet and SDK. I don't think English versions exist for any of this. Instruction set of the S-Sky is (mostly) the same as old Motorola M*Core.

Seems there is mainline gcc support as this documentation exists: https://gcc.gnu.org/onlinedocs/gcc/C-SKY-Options.html
But that's only part of what is needed. I'm not sure yet about a C library for the c-sky architecture,
And for debugger support, I found w6xx support, (which is an ARM chip) for OpenOCD, but I haven't been able to find anything about the w8xx series.
