BFGMiner

  • 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:timing=0.22 ^
       --api-listen ^
       2>log

 备注：timing详见bfgminer的README，如果当前配置的频率是400MHz,则Hashrate=400*11.8=~4Gh/s
 <math>\mbox{timing} = \frac{1}{4\times 10^9}\times 10^9</math>
  • BFGMiner MHS Cur
 MHS Cur = Diff1 Work * (Difficulty Accepted/(Difficulty Accepted+Difficulty Rejected+Difficulty Stale)*60/(Elapsed)*71582788/(1000000)
 所有的信息可以通过./bfgminer-rpc -o summary获取。
 注：如果Difficulty Accepted+Difficulty Rejected+Difficulty Stale = 0，则Difficulty Accepted/(Difficulty Accepted+Difficulty Rejected+Difficulty Stale) 取1。

Cgminer for Avalon nano

CGMiner Under Ubuntu 14.04

Download

Inside your home directory, download Cgminer
git clone https://github.com/Canaan-Creative/cgminer

Compile

cd cgminer
git checkout origin/avalon-usb -b avalon-usb
./autogen.sh --enable-icarus
make -j 4

Run

sudo ./cgminer --icarus-options 115200:1:1 --icarus-timing 0.22 -o http://stratum.pool:3333 -u  work -p pass 
or
sudo ./cgminer --icarus-options 115200:1:1 --icarus-timing 0.22 -o http://stratum.pool:3333 -u  work -p pass --api-allow W:192.168.2,W:192.168.2.1 --api-listen $@ 2>./log

LED

Idle:Green.
Working:From red to blue( frequency high to low).
Hot alert:Red blinking.

ULINK 2

Configure ULINK2 for LPCXpresso

  • Change boot mode to CMSIS-DAP
Use the Boot Mode Utility to change the mode like this: UL2_Configure B1.
  • Set jumper to 3.3V position
See Jumpers
  • Connect Avalon nano to ULINK2
Check SWD Connector Pinout, need connect SCLK,SWIO,GND only.

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
 crt_emu_lpc11_13_nxp -pLPC11U14/201 -wire=winusb -flash-load-exec nxp_lpcxpresso_11u14_periph_blinky.axf
 
 4. info scan
 crt_emu_lpc11_13_nxp -info-scan -wire=winusb
 
 5. semi_host debug
 use newlib semihost

How to debug issues with gdb (Works on OSX)

 1.Compile the program with debug options
   Change Makefile under root directory, set SW_VERSION to DEBUG
 
 2.Recompile the program
   make clean all

 3.Start gdb
   arm-none-eabi-gdb avalon_nano.axf
   target extended-remote | crt_emu_cm_redlink -g -2 -vendor=NXP -pLPC11U14/201 -flash-driver=LPC11_12_13_32K_4K.cfx
   load
 
  Then you can use gdb as you want
