**[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

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:
~~~

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.
