Sourceforge mistakenly added the trailing dot to the link. Simply remove it and the \

** [tickets:#360] "Could not write to register 'msp'" while trying to flash TI \
CC3235SF**
**Status:** new
**Milestone:** 0.11.0
**Labels:** cc32xx
**Created:** Wed Aug 31, 2022 05:48 PM UTC by Christian Spanier
**Last Updated:** Wed Aug 31, 2022 05:48 PM UTC
**Owner:** nobody
I recently updated OpenOCD (supplied by Zephyr SDK) from 0.11.0+dev-00244-g7e3dbbbe2 \
(2021-11-18-07:14) to 0.11.0+dev-00724-g42b6471c1 (2022-08-17-18:23). The new version \
is not able to flash my TI3235SF launchXL development kit board with an integrated \
XDS110 debugger via SWD. The default log output looks like this:
~~~

0* cc32xx.cpu cortex_m little cc32xx.cpu running
requesting target halt and executing a soft reset
Error: Could not write to register 'msp'
Info : XDS110: disconnected
~~~
The full log output with -d3 can be found at https://pastebin.com/R8wcFjhK.
Following a discussion on IRC, Paul Fertser suggested to add "halt" after \
"soft_reset_halt" in `openocd/scripts/target/ti_cc3220sf.cfg`, which fixes the issue \
for me.
