** [tickets:#123] TI Tiva EK-TM4C1294 launchpad broken**
**Status:** new

Hi,
I compiled openocd at 0.9.0 from git checkout (at tag v0.9.0) and I could not
connect to the TI tiva connected launchpad. By bisecting the git history I have
identified the change that caused the breakage:
064dc5daaccec5ba569d46aee0e9291352300d8b tcl/target/stellaris: Snowflake
supports SYSRESETREQ too
https://sourceforge.net/p/openocd/code/ci/064dc5daaccec5ba569d46aee0e9291352300d8b/
The error is the following:
(-snip-)
Error: memory write failed: 0x7
Error: memory read failed: 0x7
Error: jtag status contains invalid mode value - communication failure
TARGET: tm4c1294ncpdt.cpu - Not halted
in procedure 'reset'
in procedure 'ocd_bouncer'
(-snip-)
If I check out 0.9.0, roll back this CL, build, then it works again. I don't
know why it causes the failure.
There are more surprising things in the printout as well. Openocd 0.9.0 claims
that it is using RCLK - adaptive speed, which I doubt because the RCLK pin is
not wired up in the TI launchpads to the ICDI. Similarly I don't see an SRST
wired up in the launchpad's circuit diagram, which might explain the fatal
error too.
thanks,
Balazs
