| + | I used [[http://openocd.berlios.de/web/|OpenOCD]] to connect to the [[http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0210c/Chdeaegh.html|EmbeddedICE]] unit of the ARM7TDMI core. | ||
| + | Since the ACX1xx contains a pretty standard TI TMS470 ARM7 core, it uses the TMS470 IDCODE: | ||
| + | |||
| + | <code> | ||
| + | Info : clock speed 6000 kHz | ||
| + | Info : JTAG tap: acx1xx.cpu tap/device found: 0x3100e02f (mfg: 0x017, part: 0x100e, ver: 0x3) | ||
| + | Info : Embedded ICE version 1 | ||
| + | Info : acx1xx.cpu: hardware has 2 breakpoint/watchpoint units | ||
| + | </code> | ||
| + | |||
| + | This is the used configuration file for OpenOCD (using the [[http://wiki.openmoko.org/wiki/Debug_Board_v3|OpenMoko Debug Board]]) as JTAG interface: | ||
