>From looking at a picture of the JTAG connector on the pocket beagle ( http://uk.farnell.com/beagleboard/bb-pocket/pocket-beagle-board-arm-cortex/dp/2806159 ) , it looks like there are 7 JTAG connectors signals which appear to follow the TI signals as opposed to the ARM JTAG signals. Here's a crazy thought.. I've often wondered what the boot loader developers (or BeagleBone patch wizards) do when developing SPL/u-boot for a new platform like the Pocket Beagle.... Do they resort to JTAG debugging to debug the SPL and u-boot for the new platform or is everything similar enough to other platforms where the console is already up-and-running, so they can spool debug messages out the console.... If the u-boot maintainers routinely use JTAG to debug SPL/u-boot, then is there another discussion forum which discusses JTAG debugging and more detailed u-boot debugging techniques??
