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
 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)

   Compile the souce with debug, then run gdb with the following commands:
   1.arm-none-eabi-gdb avalon_nano.axf
   2.target extended-remote | crt_emu_cm_redlink -g -2 -vendor=NXP -pLPC11U14/201 -flash-driver=LPC11_12_13_32K_4K.cfx
   3.load
 
  Then you can use gdb as you want

ULINK 2

• Configure ULINK2 for LPCXpresso

1.Change boot mode to CMSIS-DAP
Use the Boot Mode Utility to change the mode like this: UL2_Configure B1.

2.Set jumper to 3.3V position
See Jumpers

3.Connect Avalon nano to ULINK2
Check SWD Connector Pinout, need connect SCLK,SWIO,GND only.
