technically, you can write to onboard registers, and even read from them, just as you can use the boundry scan to program the flash memory. Anything in the CPU is "offlimits" however (as well as anything outside the timing constaints of the boundry scan interface, ie, DRAM). I know an unfortunate coder that has a board where the flash write enable is an io line on the sa1111. To write to the flash with jtag, the sa1111 needs to be initialized though jtag...eww... _______________________________________________ http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm http://www.arm.linux.org.uk/armlinux/mailinglists.php Please visit the above addresses for information on this list.
