STARTERKIT MB91360
Chapter 7 Appendix
Solution
(see debugger introduction).
Make sure no other programs are
using the same COM-port on your PC.
Close all other applications (e.g. Flash
programmer utilities, terminals etc.)
Use the provided RS232-cable (1:1
extension type) to connect from your PC
to the „Monitor COM" connector.
If you are using a PC without a fast
UART (16550 type), you have to switch
to a lower baudrate (e.g. 38400 Baud)
and re-program the kernel according to
this baudrate (see „flash programming"
section).
Before downloading a new project to
the evaluation board, re-initialize using
the Monitor-Reset. This will erase all
valid interrupt definitions from previous
programs executed on the starterkit.
Make sure you haven't enabled any
interrupts that have no interrupt handler
(see the INTVECT.INC file) !
Note : Since the „Abort"-function uses
the external interrupt 0, interrupts are
usually enabled !
Make sure you have enabled these
units on the evaluation board using the
appropriate jumpers (e.g. JP13 for
LEDs). See the provided examples and
the hardware manual for information on
how to control the peripherals.
Adjust the potentiometer RV2 (slew
rate) according to the line.
