Welcome. I am maintaining some embedded hardvare, the board has some custom brew bios. We should add tcp/ip (preferably V6) functionlity soon. The existing BIOS the board has rather dumb, its main functionalty is BASIC configuration of the FPGAs and ASICs the board has, give a 9600/8N1 serial, and upgrade sw parts in motorola s-record format (can be streamed over serial). I already built a GCC 4.6.2 sporting newlib1.20 for the main processor what is freescale MPC8548. My question is, how can i tell ecos 3.0, to use that compiler (it has GDB 7.3, psim and python support) and how can i design a template "build>templates" for our systems? Any help are much elcome.
