Hi,

I now mannaged to compile the blinking led test program for my LPC2148 board.

I also managed to get open ocd running. (Olimex ARM-USB-OCD)

I had to start a driver called MAC_MOT.sys

I have never read that in this forrum.

Then I started open OCD (lpc2xxx_armusbocd -f lpc2xx_armusbocd.cfg)

I first tried to run insight that is part of the yagarto install, but it doesn’t start at all, no message also.

Then I tried insight which is part of winarm, this did run.

I loaded the hex file, which succeeded after a few retries.

It says that it is running, but i don’t see a flashing led.

What do I miss?

I get the message that my hex file doesn’t have debug info.

How do I generate a file with debug info, so that I can debug at source level?

Regards,

Bert

Hello Bert,

normally you would load an ELF file with Insight, not a hex file. The OpenOCD itself understands neither of both, if you want to use OpenOCD to write your target’s flash, you have to provide a plain binary (arm-xxx-objcopy -O binary elf-filename binary-filename).

Did you link your blinking led program to be run in RAM or in flash?

Regards,

Dominic

Thanks Dominic, please help me, I am trying for weeks without success.

I use the example called demo2148_blink_flash, so its flash.

I use the standard config file for open ocd for the olimex-usb-ocd.

I use the make to generate a .hex file.

I dónt understand your answer, can please tell me exacly what to modify in the makefile to generate a .elf file?

I really am brand new to this and I am a littlebit ashamed that I can’t get it to work with my 20 year software experience.

Was i t correct that I have to start this MAC_MOT.sys before starting openocd? why isn’t this documented anywhere or am I looking at the wrong places?

By the way, is it possible to add attachments here?

This is the makefile that I have:

Thanks in advance,

I am going to bed now, (its midnight again here in the Netherlands)

NAME   = demo2148_blink_flash

CC      = arm-elf-gcc
LD      = arm-elf-ld -v
AR      = arm-elf-ar
AS      = arm-elf-as
CP      = arm-elf-objcopy
OD		= arm-elf-objdump

CFLAGS  = -I./ -c -fno-common -O0 -g
AFLAGS  = -ahls -mapcs-32 -o crt.o
LFLAGS  =  -Map main.map -Tdemo2148_blink_flash.cmd
CPFLAGS = -O ihex
ODFLAGS	= -x --syms

all: test

clean:
	-rm crt.lst main.lst crt.o main.o main.out main.hex main.map main.dmp

test: main.out
	@ echo "...copying"
	$(CP) $(CPFLAGS) main.out main.hex
	$(OD) $(ODFLAGS) main.out > main.dmp

main.out: crt.o main.o demo2148_blink_flash.cmd 
	@ echo "..linking"
	$(LD) $(LFLAGS) -o main.out  crt.o main.o

crt.o: crt.s
	@ echo ".assembling"
	$(AS) $(AFLAGS) crt.s > crt.lst

main.o: main.c
	@ echo ".compiling"
	$(CC) $(CFLAGS) main.c
4

Change this line

CPFLAGS = -O ihex

to

CPFLAGS = -O binary

and

$(CP) $(CPFLAGS) main.out main.hex

to

$(CP) $(CPFLAGS) main.out main.bin

Make should then generate the binary you need.

Now launch the OpenOCD, and telnet to localhost port 4444. You could control the flashing from within Insight, too, but telnet is going to be easier.

Type

halt

poll

flash probe 0

flash info 0

flash erase 0 0 n (where n is the last sector you want to erase)

flash write 0 /full/path/to/main.bin 0x0

The number of sectors you have to erase depend on the size of your binary. The “flash info” command printed a list of sectors with their starting addresses and sizes for that purpose.

I have to admit that I’ve got no idea what the MAC_MOT.sys is about. I don’t use Windows myself, maybe someone else who got a ARM-USB-OCD could comment on this.

Regards,

Dominic

MAC_MOT.sys is the driver used by Macraigor - OcdRemote gdb server software.

I cannot understand why it is needed by the Olimex tools.

Hi Dominic, i tried what you told me.

Once i succeeded in downloading, but still no flashing led.

The openOCD software regularly stops.

This is what i get:

Hi

From flash info you can see that the flash memory is protected.

You must unprotect before erasing and writing .

flash protect 0 firstsector lastsector off

then test with flash info again.

regards,

Magnus

Hi magnus,

Here the result, the unprotect doesn’t do anything.

Hi

I’m not used to working with the LPC2000 flash but do try

flash protect_check 0

flash info 0

Regards,

Magnus

The LPC2000 doesn’t have protection in the sense of other flashes. Every block is automatically protected, and has to be unlocked prior to every operation. The OpenOCD does that automatically.

Which version of the OpenOCD do you use? Make sure you’re running a current version, you can get precompiled binaries from www.yagarto.de.

Send me a logfile (run with -d -l ) and a copy of your telnet session to Dominic.Rath gmx.de.

Regards,

Dominic

You are using the wrong flash programming variant. You have to specify lpc2000_v2 to program a 2148 in the flash configuration section of the config file.
