I studied the information that Segger retrieves from the device and reordered it, removing repeats. The commands that I thought actually DO something I tried to keep in the same order and issue them before sending JTAG commands: EMU_CMD_SELECT_IF, deassert resets, set a reasonable clock speed (Segger sets 4 kHz and 100 kHz, alternately).

I was wrong in stating that ALL of Segger's JTAG messages were 194 bytes long. From Xiaofan's log, I see quite a few on the order of 20 bytes long (that represents 64 TCK, I think), but some are shorter and some are longer. I tried some differing JTAG message lengths. 32 bytes: Info : 147 164 jlink.c:443 jlink_init(): J-Link JTAG Interface ready Debug: 148 164 jlink.c:590 jlink_reset(): trst: 0, srst: 0 Debug: 149 164 jlink.c:1733 jlink_debug_buffer(): 0000 dd Debug: 150 164 jlink.c:1733 jlink_debug_buffer(): 0000 df Debug: 151 165 jlink.c:1733 jlink_debug_buffer(): 0000 05 04 00 Debug: 152 168 jlink.c:1733 jlink_debug_buffer(): 0000 cf 00 20 00 ff ff ff ff 00 00 00 00 Error: 153 176 jlink.c:1583 jlink_usb_message(): usb_bulk_read failed (requested=4, result=-5) Error: 154 176 jlink.c:1446 jlink_tap_execute(): jlink_tap_execute, wrong result -107 (expected 4) 95 bytes (like Segger): Info : 147 146 jlink.c:443 jlink_init(): J-Link JTAG Interface ready Debug: 148 146 jlink.c:590 jlink_reset(): trst: 0, srst: 0 Debug: 149 146 jlink.c:1733 jlink_debug_buffer(): 0000 dd Debug: 150 146 jlink.c:1733 jlink_debug_buffer(): 0000 df Debug: 151 146 jlink.c:1733 jlink_debug_buffer(): 0000 05 04 00 Debug: 152 150 jlink.c:1733 jlink_debug_buffer(): 0000 cf 00 f8 02 ff ff ff ff ff ff ff ff ff ff ff ff Debug: 153 150 jlink.c:1733 jlink_debug_buffer(): 0010 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Debug: 154 150 jlink.c:1733 jlink_debug_buffer(): 0020 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Debug: 155 150 jlink.c:1733 jlink_debug_buffer(): 0030 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Debug: 156 150 jlink.c:1733 jlink_debug_buffer(): 0040 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Debug: 157 151 jlink.c:1733 jlink_debug_buffer(): 0050 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Debug: 158 151 jlink.c:1733 jlink_debug_buffer(): 0060 ff ff ff 00 00 00 00 00 00 00 00 00 00 00 00 00 Debug: 159 151 jlink.c:1733 jlink_debug_buffer(): 0070 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Debug: 160 151 jlink.c:1733 jlink_debug_buffer(): 0080 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Debug: 161 151 jlink.c:1733 jlink_debug_buffer(): 0090 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Debug: 162 151 jlink.c:1733 jlink_debug_buffer(): 00a0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Debug: 163 151 jlink.c:1733 jlink_debug_buffer(): 00b0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Debug: 164 152 jlink.c:1733 jlink_debug_buffer(): 00c0 00 00 Error: 165 343 jlink.c:1583 jlink_usb_message(): usb_bulk_read failed (requested=95, result=-5) Error: 166 343 jlink.c:1446 jlink_tap_execute(): jlink_tap_execute, wrong result -107 (expected 95) Still no good. The only thing I can think of that I haven't tried is adding those EMU_CMD_REGISTER commands, and I don't really want to do that without knowing what the command does. ~Eric _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
