Appendix B - Using an External JTAG with the BAM210

The JTAG connector is optional for the BAM210 and must be populated in order to use an external JTAG.

Follow these instructions to configure the Bambino 210 to use an external JTAG.

1. Locate the LPC11U35 Virtual COM Port Binary
2. Boot the MBED HDK into CRP DISABLED mode by shorting JP3 while connecting the USB Cable to USB1. A drive should appear.
3. Program the Interface firmware by deleting the firmware.bin file and copy lpc11u35_vcom.bin to the CRP DISABLED disk.
4. Reboot the Interface by disconnecting and reconnecting the USB1 cable without JP3 shorted.
5. Finished!

The Bambino 210 is now ready to use with an external JTAG. A virtual COM port is now available to use on USB1.

The LPC4330 signals used for the virtual COM port are listed below:
