If I may ask, how did you change the STM32 firmware?

That would also interest me very much.

Spending a lot of time poking at the miner. You'll need to have a decent background in software & hardware.

Nice work! How long have you guys had these running? Grin

Personally since about May, on a single hash board. At that time I needed to transition to another unrelated project and promptly forgot all about crypto for a few months.

Too bad you did not share.... Cheesy

I had just spent several months of my free time reverse engineering with the collaborator so a few months of slightly higher profit mining helped make me feel a little better about trading a small part of my life away for it.

No luck on Keecak? I guess you would answer no anyhow.. Grin

Looks like I have a comment in the firmware for keccak saying "experimental" so I don't think I got it working, although I don't remember putting much time into figuring out why not.

Do I understand it correctly that DiamondGroestl is added, not Groestl and not SKEIN2.

I can only vouch for Groestl with the software I posted.

Rollback is working.

Store the backup file into media/boot and reboot your device. Ensure the filename begins with "G"...bin
Cheers

unfortunately didn't work. so i decided to reflash sd card with org. image v1.1 and/or v1.2 - still not working. hashboards are showing only red leds :-(
i've already trieded to change sd cards and orange pi - doesn't matter, hashboards don't work- leds red.

Wellcome to the club of bricked X10s.

witch GX10.bin? original one? and witch update_fw.py ? meanwhile i've changed psu, sd card, hashboard.... looks like control board is defective

From these quotes I'm not sure if there are actual "bricking" problems or if people are just having trouble with the steps to change firmware. I will confirm that I am able to rollback firmware from the firmware image I posted. If ONLY the red LEDs are showing, then that should mean the control board is in firmware update mode. If the red LEDs are on and you see a blue flashing LED, then the control board is in RUN mode but sgminer has not given it work to do (either sgminer died or the pools are all down, etc). If you see blue solid LEDs then it's hashing. If you don't see any LEDs then your device is not powered Tongue

.

If you run update_fw.py and get:

Code:

dfu-util: No DFU capable USB device available

you can try editing the update_fw.py script by commenting out (adding a "#" at the start of the line) the last couple lines:

Code:

#update_firmware()
#exit_dfumode()

Run the modified script and it should have reset the STM and left it in firmware update mode. Then run:

Code:

lsusb | grep 0483

And the result sholuld be this:

Code:

Bus 007 Device 002: ID 0483:df11 STMicroelectronics STM Device in DFU Mode

(the "device" number will vary)
If instead you get:

Code:

ID 0483:5740 STMicroelectronics STM32F407

we'll have to go from there.
