BFGMiner[edit]

  • 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 ^

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[edit]
  • 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
  • How to debug issues with gdb (Works on Ubuntu14.04)
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_lpc11_13_nxp -g -mi -2 -pLPC11U14/201 -vendor=NXP -e0 -wire=winUSB -flash-driver=LPC11_12_13_32K_4K.cfx

ULINK 2[edit]
  • 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.
