Today, "JTAG" is used for many things. 1) Checking if the PCBs are ok ( the original intent ). 2) Programming the flash ROMs, or EEPROMs or FPGAs. 3) Debugging the software, with GDB single stepping (or "breakpointing") the target microprocessor. So besides "wiggling" or "shaking" in "the right way" some pins of BeagleBone, you need lots of software behind for all that to work. So the fast way to have the BB program some microprocessor is to buy a cheap USB-JTAG adapter supported by these two software packages: http://openocd.sourceforge.net http://urjtag.org Best regards Paulo Ferreira -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
