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]
run 1: BEFORE change
run 1: BEFORE change, the pre-placed J6 on M1 collides to C27 on JTAG adapter.
run 2: AFTER change
- 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.
run 1: BEFORE change
run 1: BEFORE change, the pre-placed J6 on M1 collides to U1'd body on JTAG adapter.
run 2: AFTER change
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.

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].
Test tools
1. Build the libftdi-1.0 and compile new ftdi eeprom. [3]
2. Script file for reflash jtag/serial board, [4], [5]
Test Procedures
Step 1:
# 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 2: 1. unplug jtag and replug
