Error: Target not halted

Postby mgiaco82 » Fri Aug 21, 2009 1:24 am

I have a problem with OpenOCD and GDB. Debugging works fine if I erase at least the first sector of the lpc2148 – I use telnet for that (flash_erase_sector 0 0 0). So if I start a debugging session in Eclipse everything works fine. But if I stop the session and try to restart a new one I get this error.

As recently as I erase at least the first sector of the on chip flash via telnet it works fine again. Sometimes I must halt the target before the erase command works.

I use the latest Version of OpenOCD with FTDI-Lib and the latest Eclipse and Zylin tools.

These are my gdb init commands:

Code: Select all
target remote localhost:3333
monitor poll
monitor reset init
monitor sleep 500
monitor mww 0xE01FC040 0x0001
monitor mdw 0xE01FC040
# needed for gdb 6.8 and higher
set mem inaccessible-by-default off
monitor flash probe 0
load
break main
continue


I do not know what´s wrong.

thanks mgiaco

So now it works but i need to erase every time i start a session but why?

Code: Select all
target remote localhost:3333

monitor poll
monitor halt
monitor sleep 500
monitor flash_erase_sector 0 0 0

monitor soft_reset_halt

monitor reset init
monitor sleep 500

monitor mww 0xE01FC040 0x0001
monitor mdw 0xE01FC040

# needed for gdb 6.8 and higher
set mem inaccessible-by-default off

monitor flash probe 0

load
break main
continue

Try this:

target remote localhost:3333
monitor reset halt
load

Hello Freddie,

Code: Select all

monitor mdw 0xE01FC040
set mem inaccessible-by-default off
load
Error erasing flash with vFlashErase packet

No it doesn´t work.

I've proposed this set:

target remote localhost:3333
monitor reset halt
load

You entered:

target remote localhost:3333
monitor reset halt
monitor reset init
monitor sleep 500
monitor mww 0xE01FC040 0x0001
monitor mdw 0xE01FC040
set mem inaccessible-by-default off
load
break main
continue

You see any difference?

4\/3!!

To enable flash programming via load in gdb you need to make sure valid flash banks are configured:
flash bank lpc2000 0x0 0x7d000 0 0 0 lpc2000_v2 14765 calc_checksum
and also a working area to speed things up - look at the default lpc2148 cfg for an example.

What will happen when gdb connects openocd will send the memory map to gdb. Then when you use the gdb load cmd it will erase the flash for you and then write the new flash.

The following cmds are not required, they will be done automatically:
set mem inaccessible-by-default off
monitor flash probe 0
http://openocd.berlios.de/doc/html/GDB- ... nd-OpenOCD may provide more info.

If you are still getting trouble then attach a full openocd debug log -d3.

I do not use lpc's, so these guidelines are general.

Cheers

Hello Freddie,

Okay so i try your commands and i get these errors.

Code: Select all
target remote localhost:3333
0x0000033c in main () at main/src/main.c:226
226         if (timer_cnt0 > counter) {
monitor reset halt
load
Error erasing flash with vFlashErase packet


@ntfreak

thx i will have a look at that.

thx

What's the output of OpenOCD when you issue those commands?

You can also try this method:
To find out what's wrong start OpenOCD as usuall and open Command Prompt (cmd) and type:

telnet localhost 4444

this will connect you to OpenOCD via telnet.

Now you can try commands like:
reset halt
poll

and post the output (of telnet and of OpenOCD in the other command prompt) here.

You can also try to flash the chip via telnet with flash write_image ... (the details in the User's Guide of OpenOCD)

Even I am facing a similar problem with wriggler. The microcontroller is not halted after reset. The telnet output is :

I can program the chip using H-JTAG, so apparently the jtag hardware is OK. I have checked the nrst - Pin 15 - of jtag header does go low.

Anything else I can try ?

Thanks

Hello Rakesh,
Can you please let me know if you resolved this issue? I am facing similar problem with openOCD and LPC2148.

Thanks!

Hello,
I am getting the same error of Target not halted. Also d monitor command error pops up and if I remove all the monitor commands,I still get d msg "Error: Launching main.elf file"...
Anyone please tell me the solution of at least one of these problems.....
