LPC Link Posibilities

IS there any part of the (free) LPCXpresso IDE package that can be run separately in order to provide a GBD server that I can use to write my own debugger interface/flash loader tools.

Is there any documentation on this?

How does flash magic tm connect?

As an alternative is there any documentation on the USB protocol of the LPC-Link as a device?

Regards, Mike

Hi. This is a bit heretical, but I don't really like to use an IDE at all!
Also I am more than somewhat fussy about the exact operation of the debug capabilities exposed by the LPCXpresso IDE package.

I fully accept that this is my problem and not anyone else's.

With sufficiant skull sweat and reading the ELF/DWARF specs and the SWD specs and the debug components of the Cortex, I can write a standalone debugger for Cortex M3 that displays and operates exactly how I want. [And I know that this will be a major undertaking! I would hope to make this either open source or free to download.]

There is a perennial problem of actually interfacing to the JTAG/SWD pins of the device under test. I don't want to have to design yet another debug adapter because no one will publish their comms protocols.

I was hoping to be able to interface to the LPC-Link becaise it is really cheap. [Have you seen the price of Segger's J-Link for example?]

Failing details on the LPC-Link interface protocols, is there any information for reprogramming the ARM chip on the LPC-Link with my own custom code?

There is no public API to the LPC-Link itself. I'm not sure what you are actually trying to achieve, but you can invoke the flash programmer used by LPCXpresso IDE from the command line, as detailed in:

With regards to Flash Magic this connects via the MCU's ISP functionality, which depends upon the MCU in use  (eg serial, ethernet). For more details, see

Partially answering my own question, there is a page on the Code-Red site "Using command line GDB". However, I find it difficult to understand what one would actually type, presumably into a command window.

It would still be nice to have USB protocol documentation for the LPC-Link.

Regards.
