Dual core debug LPC4370 with J-Link and keil problem

Hi,
I have build a dual core project on LPC4370, ,It works perfectly. But I can not start debugging on Cortex M0 core, j-link complains flash downloading fail! my code is in RAM for cortex M0, here is the M0 project setup,
you can see Keil setup in here,

imageupload.co.uk/image/5nMa

Do you have any idea what's wrong?

Hi,

The message come from Keil, which seems to be configured to use its own flashloaders,
but does not find a matching one (since it is RAM), but in your settings it is specified as ROM.

You might have to have a look at how to create a RAM debug configuration for Keil.
segger.com/IDE_Integration_Keil.html describes how to use the J-Link-integrated flashloaders which will also know whether it is flash or RAM.

Best regards
Johannes

Thanks,Johannes.
I have solved the flash download problem, But now when I start debugging M0 after the M4 core, my debugger start and stop the M4 core instead,
Would you please show a simple dual core working project? that would be highly appreciated.
Regards

when I start a new project and set it for Cortex M0, the j-link can not detect the JTAG chain,but in the M4 project the j-link can detect three cores,I have manually deleted the JLinkSettings.ini file from M0 project and copied the M4 JLinkSettings.ini to M0 project,Now j-link can detect the cores, and when I select the M0 core the M4 core will start and stop, In other words I still could not do a debug on M0 core,
Please see the pictures

Would you please share a simple working project?
