This JTAG adapter board works with the BeagleBoard and BeagleBoard-xM. The Flyswatter2 is 5 to 10 times faster than the original Flyswatter. TinCanTools has a new JTAG debugger at Flyswatter2 that has support for OpenOCD and ARM Cortex A8 processors: OMAP3530 BeagleBoard and DM3730 BeagleBoard-xM. See Beagle board OpenOCD page about status and usage of OpenOCD for Beagle.įor BeagleBoard JTAG debugging, there are some HW interfaces available. The main open source JTAG software is OpenOCD. It would be very interesting to get the JTAG working with open source tools.

See ICEPICK configuration page for more details about how OMAP3 JTAG hardware needs to be configured. The following picture is from a TI OMAP JTAG presentation: Note that it will not work with the Spectrum Digital XDS510USB (non-plus) as it does not support a target with 1.8V JTAG. The 14-pin TI JTAG connector that is used on BeagleBoard is supported by a large number of JTAG emulation products and has been tested using Lauterbach, Green Hills, Spectrum Digital XDS510USB+ and TI XDS560 emulation pods. Depending on your JTAG tool, you'd need a 20-pin to 14-pin TI adapter.Īttention: JTAG on BeagleBoard uses 1.8V! This is the same header interface as used in other TI products and is NOT the standard 14 pin ARM layout. For JTAG pin out see section 8.16 of BeagleBoard HW Reference Manual (rev. The BeagleBoard comes with a 14 pin TI JTAG connector.
