Hi,

I have the LPC824 and am trying to debug it using an lpcxpresso v2 board which has a LPC1549 on via SWD. I'm using the LPCxpresso IDE

Currently I am having no joy so far. This is my error:

""Error in final launch sequence
Failed to execute MI command:
-target-select extended-remote | crt_emu_cm_redlink -msg-port=60254 -g -mi -2 -pLPC824 -vendor=NXP -vc -reset= -ProbeHandle=1 -CoreIndex=0 -flash-driver=LPC800_32.cfx
Error message from debugger back end:
Remote communication error. Target disconnected.: No error.
Remote communication error. Target disconnected.: No error.""

Just for starters I'm using the periph_blinky to see if I can debug anything on the chip.

I believe I have followed the instructions in the datasheet, user guide and these links:

https://www.lpcware.com/content/faq/lpcxpresso/debug-design
https://www.lpcware.com/LPCXpressoV2Boards
(see piccy attached)

I have configured my pcb to match what's in the datasheet and I have a pull up on pio0_12 which is the ISP entry (see piccy attatched), I have alos configured the V2 board to have J1 shorted, and J2 shorted on pins 2 & 3.

Please tell me where I have gone wrong.

Thank you.

Andy

Off hand, I don't see anything wrong with your debug circuit provided you've connected the signals to the 10 pin debug connector as you've indicated. The JP1/JP2 settings on the Xpresso v2 probe are correct, but in practice, I don't think the JP2 setting matters. Perhaps the problem is elsewhere in your board design.

You haven't said anything about which LPCXpresso version you're using. The following example presumes you're using the latest LPCXpresso 7.9.0 release*

*As a quick experiment, use the Redlink server program (redlinkserv.exe) to determine whether you have any kind of debug capability to the LPC824.

1. On Windows, open a DOS command shell, and navigate to the LPCXpresso <installation>/bin directory. Be certain you first DFU a firmware probe to the Xpresso v2. On Windows, you can DFU the CMSIS-DAP probe using this command script:

boot_link2.cmd

or this command line:

dfu-util.exe -d 1fc9:000c -c 1 -t 2048 -R -D LPC432x_CMSIS_DAP_NB_V5_112.bin.hdr

Note Linux and Mac OS X hosts use a slightly different command line ('-c 0').

2. Start the Redlink server program

redlinkserv.exe -commandline
C:\nxp\LPCXpresso_7.9.0_455\lpcxpresso\bin>redlinkserv.exe -commandline
redlink>probelist

You'll know after the WIRESWDCONNECT command whether or not you have a debug connection to the target.

Thanks and regards,

Hi,

Thanks for the quick reply.

So.. No I'm using 7.3, I am going to update and try again. But in the mean time I have tried the steps you have outlined above and this is the output I get from my cmd promt:

C:\nxp\LPCXpresso_7.3.0_186\lpcxpresso\bin>redlinkserv.exe -commandline
redlink>probelist

redlink>exit

Don't really know what it means, but it looks similar to your output :-)

The big difference I can spot is in the probe description,

I have LPCLINK2 Redlink compared to your LPC-LINK2 CMSIS-DAP V5.112 NB.

Hopefully this gives you some insight into where the problem may lie.

Cheers,
Andy

OK,

so now I'm running 7.9 and have repeated your instructions.

Actually, the first time I followed them with 7.3 I ran the boot_link2.cmd and nothing happened and then proceeded to the next step the result of which is the previous post.

Now with 7.9 I attempted to run the boot_link2.cmd again and the altnerative method outlined, please see the result:

c:\nxp\LPCXpresso_7.9.0_455\lpcxpresso\bin>boot_link2.cmd
Nothing to boot

It means your LPC-Link2 is not connected, or it is already booted.

Please run boot_link2 when the device is connected to the PC (and has been power cycled).
