BFGMiner

• Run

 Run under Linux
 ./bfgminer \
       -S ICA:/dev/ttyACMx \
       -o stratum+tcp://stratum.ozco.in:80 -O mikeqin.avalon:1234 \
       --set-device ICA:baud=115200 \
       --set-device ICA:reopen=timeout \
       --set-device ICA:work_division=1 \
       --set-device ICA:fpga_count=1 \
       --set-device ICA:probe_timeout=100 \
       --set-device ICA:timing=0.22 \
       --api-listen \
       2>log

 Run under Windows
 bfgminer.exe ^
       -S ICA:\\.\COMn ^
       -o stratum+tcp://stratum.ozco.in:80 -O mikeqin.avalon:1234 ^
       --set-device ICA:baud=115200 ^
       --set-device ICA:reopen=timeout ^
       --set-device ICA:work_division=1 ^
       --set-device ICA:fpga_count=1 ^

       --set-device ICA:timing=0.22 ^
       --api-listen ^
       2>log
 
 Note: See the details about the timing in README. It works ~4GH/s(400 * 11.8) at 400MHz.
 timing = (1 / (4 * 10 ** 9)) * 10 ** 9 (python format)

• MHS Cur calculation

 MHS Cur = Diff1 Work * (Difficulty Accepted / (Difficulty Accepted + Difficulty Rejected + Difficulty Stale)) * 60/ Elapsed * 71582788 / 1000000
 Note：
 1.if Difficulty Accepted + Difficulty Rejected + Difficulty Stale = 0, then Difficulty Accepted / (Difficulty Accepted + Difficulty Rejected + Difficulty Stale) = 1.
 2.Get all the infomation through ./bfgminer-rpc -o summary

LPCXpresso

• Installation and Activation

 LPCXpresso download link 
 Free Edition is enough. Then activate it. 

• LPC-Link diagnostics

 Diagnostics when connecting to LPC-Link
 
 1.  lpc-link info
 crt_emu_lpc11_13_nxp -info-emu -wire=winusb
 
 2.  target info 
 crt_emu_lpc11_13_nxp -info-target -pLPC11U14/201 -wire=winusb -4
 
 3. burn and run axf file

FAQ

• How to debug Avalon miner App under Chrome browser ?

1. Enter the follow under the address bar.

   chrome://extensions/

2. Change to Developer mode in the right corner.
3. Select Avalon miner background page, Enable console log in the Developer Tools. Filter: Status

   utils.enableLog()

4. Then open Avalon miner App, and update Pool Settings, then Enter mining.

You can check firmware version in the Miner App, and check the Status in the Developer Tools.

Don't forge update your device permission under Linux.

Under Ubuntu 14.04 LTS, you can add a rules under /etc/udev/rules.d, Make sure the user is a part of plugdev group
