Hello, I am seeing some reset issues on the below boards. They're reproducible without unplugging, i.e. openocd does get them into a sane state on startup. I'm fairly sure that "reset" worked when I contributed the configs, requested to test various settings.
In particular "reset" on the XMC4500 General Application Kit has regressed; on the SDRAM version it still works okay. "reset init" doesn't work on either, not sure if a regression - a timing issue maybe? A manual "halt" always works as expected on either board. Found while testing Jeff's xmc4xxx flash driver, which needs the device in halted state. Setup: source [find interface/jlink.cfg] transport select swd source [find board/xmc4500-application-kit-general.cfg] # or: source [find board/xmc4500-application-kit-sdram.cfg] followed by interactive commands from telnet localhost 4444. http://openocd.zylin.com/#/c/2721/ - pointed at for LPC1857 - changes General's output, but does not seem to help. Any other patch to try? Regards, Andreas xmc4500-application-kit-general.cfg: > reset in procedure 'reset' in procedure 'ocd_bouncer' Polling target xmc4500.cpu failed, GDB will be halted.
