Cannot debug with LPC4330

[Seidleroni]

I’m just starting with Visual GDB and I am trying to debug using the Segger J-Link. When I run the debugger, I get the following in my GDB Server Log. What do I need to do to get this working with my project?

[support]

Hi,

It looks like the J-Link software might be getting invalid readings from the chip. Have you checked with Segger whether this chip is officially supported? Perhaps you are missing some configuration option of the J-Link GDB stub?
You can also try using OpenOCD instead. We can share our experimental script files for LPC4330 if this helps.
