I rewrited openocd config for launchxl-rm46 board, because config in repo is invalid.

openocd run correctly, but when i try to make target halt i see
Error: Timeout waiting for halt
when i try reset halt i see
Info : JTAG tap: rm46.jrc tap/device found: 0x2b95502f (mfg: 0x017 (Texas Instruments), part: 0xb955, ver: 0x2)
Info : JTAG tap: rm46.cpu enabled
Warn : rm46.cpu: ran after reset and before halt ...
Error: Timeout waiting for halt
in procedure 'reset'
in procedure 'ocd_bouncer'
may be i have mistake?
