The reason i want to use ethernet is that on my embedded target serial port is already used for message logging purpose . so cannot use serial port for debugging . basically i want to put breakpoints at runtime and debug modules . please suggest me alternative debug mechanism too especially useful for debugging modules on embedded targets . can i know the exact repository from where i can download kgdboe patch which i can apply for 2.6.35 kernel onwards or 3.x series kernels .
