Using the LPC4370 on the LPC-Link2 card

I would like to use ]the LPC4370 on the LPC-Link2 card in much the same way as it is used by the LabTool card.

As a start I compiled the basic "while(1) {i++ ;}" project to RamMLoc128 but I have not been able to download it to the LPC-Link2 card.

I tried both LPCXpresso 6.1 and RedSuite 5.2.

RedProbe+ was connected to the 10 pin J2 connector on the card via the JTAG adapter.

The USB connector on the LPC-Link2 card was connected to a USB port on the computer.

If I select RedProbe Family on the LPCXpresso 6.1 Debug configuration page and click the Debug button I get the error message

Quote:

LPC-Link (HID) not found.
This could be because it is disconnected, not powered, or already in use"

Trying the Redlink option gave the following message box

Quote:

JTAG configuration.
No JTAG Device selected. Select a Device before continuing

I must be doing something stupid so please could somebody tell me the correct connections and options to
program the LPC4370 on the LPC-Link2 card. I have searched through the documentation without success.

Thanks for any help

JohnR

Hi

Thanks for your message. I am still having problems trying to launch your example.

If I run Debug a message box appears indicating the RedProbe is present.

1 emulators found.
Select the emulator to use

If I OK this box for the only emulator shown the next message is

No JTAG Device selected. Select a Device before continuing

No JTAG file is created, whereas for the LPC4350 code on my Diolan boards the jtag file is always recreated.

I can get the same fault sequence if I delete the launch item "LPC4370_LEDblinky Debug.launch"
and then run debug.

Could my problem be that the LPC-Link2 is code protected?

If so what can I do - at present I don't have easy access to the serial port for Flash Magic but is there any other way?

OK, I can replicate some issues using LPC-Link1 / Red Probe+ to debug LPC4370 (using an LPC-Link2 debug probe is fine). We'll investigate.

Thanks for the reply.

I hope you can find the problem as I am really stuck at the moment.

I have some LPC1768 boards with the LPC_Link.

Would I be able to use the LPC_Link cut off from the LPC1768 and hooked into J2 as a temporary measure?

John.

Another inexpensive dev board is the Bambino 200

http://www.micromint.com/component/content/article/53-products/196-bambino200.html

It offeres quite a lot for a $25 board.

The LPC-link2 schematic says J2 is attached to LPC4370 JTAG pins

hi

Thanks for the suggestion. The reason I am trying to use the LPC4370 is the built-in high-speed ADC, which should simplify my present system based on a LPC4350 and external ADCs.

I have tried J2 and J7 without success. I have also recycled one of LPC Link sections of a LPCXpresso board to connect using J4 on the LPC-link2 but have not had any success so far.

All very frustrating and time-consuming.

John.

What about JP1?
J7 is definitely JTAG for the debug target when using LPC LINK2 as debugger
J2 is LPC4370 JTAG.
How is the device powered?

First I have a stupidity that I must confess to - I had reversed the position of the 10 pin plug on the JTAG adapter.

Now that is corrected, M4 and M0 appear in the JTAG list - chose M4.

Running Debug fails and produces the following message

LPCXpresso Debug Driver v6.0 (Oct 16 2013 02:04:38 - crt_emu_lpc18_43_nxp build 1212)

From LPC43xx.h 0x40053100 is a register,
RESET_CTRL0; /*!< (@ 0x40053100) Reset control register 0 */

What does this message mean then?

Thanks again,

John.

Hi,

See my previous message re stupid mistake.

My RedProbe is connected to J2.

JP1 is open as I think I am trying to boot from USB DFU?

John.

This is the issue with debugging LPC4370 using a RedProbe+ or LPC-Link1 that we were referring to in a previous post.

We have identified a fix and this will be incorporated into the next LPCXpresso 6 release.

Until then, you will need to use a second LPC-Link2 to debug the LPC4370 on your "target board LPC-Link2". This is generally a better idea anyway, as you can then carry out parallel debug connections to the Cortex-M4 and Cortex-M0 cpus.

Thanks.

Just to check the setup using 2 Link2s

#1 is connected to the PC with the compiler using the USB connector.
#2 is powered using the USB connector and a USB power supply. This will be the target?

Do I connect J7 on #1 to J2 on #2 ????????

Sorry for the dumb question.

John.

Yes - J7 on #1 to J2 on #2.

And if you are using the SPIFI flash to hold your LPC4370 application code (as per the example at http://www.lpcware.com/content/faq/lpcxpresso/using-lpclink2-as-lpc4370-eval), make sure that JP1 is fitted on #2 too.

Hi,

Still no joy.

I have jumpers on both JP1s and LPC-link(HID) selected on the debug configuration page.

Running Debug then gives me the error message

What am I dong wrong?

I thought you were using LPC-Link2. LPC-Link is the OLD version found on the original LPCXpresso boards.

The debug driver for LPC-Link2 is called Redlink. FYI, it is not called LPC-Link2 because the Redlink debug driver supports multiple debug adapters, including LPC-Link2 and CMSIS-DAP.

Thanks.

Works fine after changing from JTAG to SWD for Redlink.
