According to the Mini RC Manual .. Section 12 lists all the LED information
Continuous blinking – Program is in an infinite loop.
Five blinks before turning solid – Invalid register accessed in user
program.

Something worth pointing out from Section 14 ..
Also, if the PROG button is pressed at the same time as you turn on the unit, diagnostic mode will be entered and the LEDs will cycle through a distinctive pattern. This mode is not useful for users and the user program will not execute. Simply power cycle the unit to return to normal operation.
You should be able to program the RC though .. maybe IFI can shed some light on this.
