Hi all, I am facing a strange problem: the JTAG tap is reading the right value from my device but the value I defined on config file appear changed during detection.
This is the config file: # The bs tap if { [info exists BSTAPID ] } { set _BSTAPID $BSTAPID } else { set _BSTAPID 0x1b900f0f } jtag newtap $_CHIPNAME bs -irlen 4 -ircapture 0x1 -irmask 0xf -expected-id $_BSTAPID # The CPU tap if { [info exists CPUTAPID ] } { set _CPUTAPID $CPUTAPID } else { set _CPUTAPID 0x07926041 } jtag newtap $_CHIPNAME cpu -irlen 4 -ircapture 0x1 -irmask 0xf -expected-id $_CPUTAPID # The SDMA tap if { [info exists SDMATAPID ] } { set _SDMATAPID $SDMATAPID } else { set _SDMATAPID 0 } jtag newtap $_CHIPNAME sdma -irlen 4 -ircapture 0x0 -irmask 0xf -expected-id $_SDMATAPID # The SJC tap if { [info exists SJCTAPID ] } { set _SJCTAPID $SJCTAPID } else { set _SJCTAPID 0x088231d } jtag newtap $_CHIPNAME sjc -irlen 5 -ircapture 0x1 -irmask 0x1f -expected-id $_SJCTAPID Notice I defined SJC IDCODE = 0x088231d, but during detection the openocd is looking for 0x0088231d See: Open On-Chip Debugger 1.0 (2009-01-16-08:27) svn:1324 BUGS?

Someone here know about this problem?
