[edit] Change Notes
- place C27 and C28 away from J6's housing (P/N: Molex 87832-1420) on Milkymist One board when hooking up, see [1]
- lengthen one side of board edge to 1.6mm to let J6's housing on M1 not collide U1's body, U1, R1, R2, R12, R13 are all moved down 1.6mm.
[edit] Gerber Overview
Before do below, generate drill with
drill units: inches, zeros format: decimal, drill origin: auxiliary, all other options off/none
The gerber image overview generated by Werner's EDA tool:
adam@adam-laptop:~/extras-m1/jtag-serial/gerber$ /home/adam/eda-tools/fab/drl2gerber usb_jtag.drl > usb_jtag.gbr adam@adam-laptop:~/extras-m1/jtag-serial/gerber$ /home/adam/eda-tools/fab/prettygerbv -d usb_jtag.gbr usb_jtag all jtag_rc2_gerber_overview.png
Be noticed that the final drill file we generated with "suppress leading zeros" for zeros format and send to pcb maker.
[edit] Bare Panelized PCB
[edit] Profile measurement
[edit] Assembled board
[edit] Manufacturing serial number
- 1107001 ~ 1107200 : YYMM###; YY = 11, means 2011 year; MM = 07, means July; ###, means number; Be noticed that previous run1 (or others), there's hex coded serial number generated by FT_Prog utility for Windows from FTDI [2].
[edit] Test tools
1. Build the libftdi-1.0 and compile new ftdi eeprom. [3]
2. Script file for reflash jtag/serial board, [4], [5]
[edit] Test Procedures
Step 1: Make sure the pod connected on a stable +5V[1] supplied by mini-USB cable and its current is good without huge consumptions. After test, viewing solderability of board. The other 5 remaining 5 boards were assembled by removed rc1 parts, then get all passed.
Results: 200pcs / 200pcs; there's no huge current consumptions. but got one piece with U5's pin 31 and 30 shorted by manually visual inspection.
Step 2:
# cd ftdi_eeprom # lsusb ; get usb device name, for example 002:003 # sudo ./flash_jtag.sh /dev/bus/usb/002/003 1107001 ; vendor_id=0x20b7 product_id=0x0713 self_powered=false remote_wakeup=false chip_type=2232H max_power=90 in_is_isochronous=false out_is_isochronous=false suspend_pull_downs=false use_serial=true change_usb_version=false usb_version=0 manufacturer="Qi Hardware" product="Milkymist One JTAG/Serial" serial="1107001" FTDI eeprom generator v@EEPROM_VERSION_STRING@ (c) Intra2net AG <opensource@intra2net.com> Found device with VID:PID : 0x20B7:0x713 EEPROM size: -1 FTDI erase eeprom: 0 FTDI close: 0 FTDI eeprom generator v@EEPROM_VERSION_STRING@ (c) Intra2net AG <opensource@intra2net.com> Found device with VID:PID : 0x20B7:0x713 EEPROM size: -1 Used eeprom space: 128 bytes FTDI write eeprom: 0 FTDI close: 0
Step 3: 1. unplug jtag and replug

Step 4: make sure JTAG daughter board detected as new high speed USB device and attached. Follow Step 3 of http://en.qi-hardware.com/wiki/JTAG_Serial_Cable_run_1_for_Milkymist_One#Tests_and_Results to verify JTAG daughter can work with Milkymist One board.
[edit] Available Stocks
200 pcs, total inputs is 200 pieces, and 100% passed after tests by above procedures.
