I hope I'm closing in a bit on the problem with "reset run" on i.MX27.
- "reset run" will fail with the error messages below - the problem appears to be that OpenOCD believes that the target is halted when it is in fact running. It could be that MOE=0xe is simply what is returned when the target is running rather than halted... - cpsr is also reporting bogus values, which would make sense if the target is running instead of halted - if I issue a "halt" or "poll" after the "reset run", then the OpenOCD syncs up to the state of the target.
