Is there a firmware update to support - Extranonce subscription?

Couldn't find a way to do it. You basically can't mine on Nicehash because there are huge rejections 10-20%.



I have a working build of 4.9 that will run on the beaglebone but the libraries I compiled with are newer / older than some of the ones on the most recent firmware. This in turn causes a ton of problems. I've been trying to get a build of angstrom1-4 built to run in qemu so I could match the libraries but I just dont understand how I can get my image to boot and the yocto1-4 distribution doesn't build on the latest ubuntu either. Sad If I could boot into angstrom or a yocto build emulated in qemu using the beaglebone as hardware with a dev set that includes apt-get I'd go through the trouble of compiling a new cgminer but I'm pretty much stuck at that step and am running a incompatible image instead.

Steps I took:
Unknown-Image (I've compiled over 20 images at this point, I have no idea which one I'm running anymore)
compile linaro-qemu
run qemu-system-arm -M beaglebone
Compile cgminer (in qemu running an armv7 system using beaglebone as forced hardware set)
Elf edit to linker for angstrom build on s2
Elf edit to point to /lib and /usr/lib on s2
scp binary to s2
Library errors / Segment fault (I'm assuming this is because I didn't compile using the arm linker in the angstrom build and trying to force that linker causes a seg fault in my vm that I build on)
Huh

I can provide the non working binary if anyone is interested.

Also, all of this, because I honestly cant figure out how to properly setup a cross compilation tool chain  Grin
