USB support for GDB

USB support for GDB

[Sachin Bharadwaj]

Hi,

How do I start modifying Insight/GDB for communicating through USB. I
have a sample Linux USB driver, with which I want to interface the
Insight/GDB 5.1.

Any quick response will be highly appreciated.

Sachin

I don't know anything about talking to USB devices, but I would guess
that you would need to create a new serial_ops structure (see
serial.h) pointing to functions that do the right thing, and call
serial_add_interface to register it.

Then you'll need to add a case to serial_open in serial.c to parse the
argument to 'target remote'.

Would you use Micosofts WDM DDK, to assist in the development of the device 
drivers for the particular target system. Would the device driver be wrote 
at a layer below GDB & then use Win32 API calls to communicate with the 
Device Driver which in turn would communicate with the target device

If I were working on Windows?  I don't know much about Windows
development, so I couldn't say.  Sachin said he was using Linux, and
already had a sample driver.
