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

Thanks.

Works fine after changing from JTAG to SWD for Redlink.

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.

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?

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.

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.

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.

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?

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.

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?

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.

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

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.

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.

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?

JohnR
