I am getting this same communication failure with May 16 2008 svn 657 release.
Error: jtag.c:1368 jtag_examine_chain(): JTAG communication failure, check connection, JTAG interface, target power etc.
Error: jtag.c:1562 jtag_init(): trying to validate configured JTAG chain anyway
Error: jtag.c:1461 jtag_validate_chain(): Error validating JTAG scan chain, IR mismatch, scan returned 0x0000
From searching here I can’t determine what the fix might be.
Other posts suggest that it may be one of …
- A bug in release(s) of Openocd where a prior release may work?
How does only change what file( s) to run another version without another install?
- Posts indicate it could be a power issue on USB. I have seen a suggestion of buying a power hub to fix that. I doubt it for me with a new
DELL inspiron with usb 2,0
- Increasing speed or reset values but that hasn’t worked for me.
Anybody have an xscale board working under openocd? Can you breakpoint or just flash? What is your configuration exactly?
