Unable to debug demo programs

schoelch_frank — Sat, 23 Feb 2019 01:13:27 GMT

Hello,

to upgrade from an old LPC2134 design based on IAR EWARM to LPC54102, I installed the current version of LPCXpresso 8.2.2 under Win7 and purchased the demoboard OM13077.An upgrade to MCUXpresso is not intended at the moment as the old LPC2000 is not supported.

For the first test, I tried to debug the periph_blinky program. However this did not work as desired.

At first, errors "No source found" were displayed for various adresses 0x... Pressing F8, the application could be set into run mode, but the LED on the demoboard stayed dark. Also, the debugger only showed the .axf under Thread #1 and main() has not been shown.

Then I opened the periph_adc and tried to debug this. since then, an error g_pfnVectors() at 0x0 occurs. Pressing F8 leads to the same error within a quarter of a second or so. It has been impossible to run the application at all.

I deleted the project directory and started from the beginning, but not the periph_blinky also shows error g_pfnVectors() at 0x0 . I tried to erase the flash using the IC symbol in the ribbon bar, but this leads to a timeout error after about 5 seconds. Reinstalling LPCXpresso did not help.

All jumpers on the demoboard are in the factory settings which seems to be correct according to the manual.

Is this a software fault or am I doing something wrong?

Hello Frank Schoelch ,

- Please make sure choose right chip part number when debug .

- The MCUxpresso IDE support this board now, the MCUXpresso SDK lib also support this board,

you can development lpc54102 based on SDK.

https://mcuxpresso.nxp.com/en/builder

- I have ordered this board, after get it , I will also test it on my side .

Have a great day,
TIC

Hello,

I checked the device setting and it's fine. Also I installed LMPXpresso on a different computer and it shows exactly the same issues. I even received a second new demoboard and it does not work. I tried to program the flash manually and got the following log:

Is there a way to update the firmware of the LPC-Link2 on the OM13077?

Re: Unable to debug demo programs

Updated the debugger Firmware to the current 2019 version using LPCScrypt and it didn't help.

Can you try booting the board into ISP mode before you try to start a debug session and see if that helps. For more info see : https://community.nxp.com/message/630748

schoelch_frank — Tue, 26 Feb 2019 11:31:27 GMT

Entering ISP mode didn't help, the old messages are still shown.

I tried lpcscrypt to check if there's a basic communication and it's unable to read the device ID:

C:\nxp\LPCScrypt_2.1.0_842\bin>lpcscrypt querypart
Error opening COM5: Read Timeout
(Sometimes ISP reset, or erasing the flash, can help...)
Previous error(s) stops further processing
Error: <Command line>:0: Read Timeout
Script cmd: batchmode 1
Last target cmd: =print 18886
Terminated with errors

C:\nxp\LPCScrypt_2.1.0_842\bin>

However, if I flash the J-Link firmware into the LPC-Link2 and use Segger J-Flash Tool, I can read the Core ID correctly and I can also read back the content of the flash of the LPC54102.

I suppose there's a major bug inside this development toolchain.

Re: Unable to debug demo programs

converse — Tue, 26 Feb 2019 13:53:39 GMT

A couple of things

- when using LPCscrypt you are connecting to, and programming the on-board debugger - not the target chip. So, running 'query part' will read the part number of the LPC43xx that is the debugger.

- are you sure your target is an LPC54102J512. I have seen a similar problem when attempting to debug the wrong part. It is vitally important that the IDE know exactly what the part number of the debug target is.

Device selection should be correct as shown in the picture. This is preconfigured in the project periph_blinky contained in the zip-file lpc5410x_lpcxpresso_3.01a.zip of the Examples folder of LPCXpresso.

Could someone of the NXP team test if there's an issue with the compatibility of LPCXpresso 8.2.2_650 and the Demoboard OM13077?

Hello Frank

I test on my side, the same error with you . I haven't find the really reason.

While, it can work well on MCUXpresso IDE, also now we recommend customer use

this new IDE, all the updates about LPC will based on it :

https://www.nxp.com/support/developer-resources/software-development-tools/mcuxpresso-software-and-tools/mcuxpresso-inte…

There are two libraries support LPC54102 now, LPCopen and SDK, recommend use SDK.

The way to use LPCopen on MCUXpresso IDE is the same with LPCxpresso IDE.

About how to install and use SDK on MCUxpress IDE, please refer to "MCUXpresso_IDE_User_Guide.pdf".

Have a great day,
TIC

Hi, thanks *a lot* for your effort!

Will this error be solved in the LPCXpresso suite?

I'd like to use MCUXpresso, however I also have to support the old LPC2134 design. Maintaining two different IDEs is a bit of a pain.

Hello Frank Schoelch,

There isn't any update for LPCxpresso IDE, so sorry for the inconvenient to you.
