Yes. > Mainly, where to start? Look at the ARM and MIPS targets - MIPS is newer but a bit less mature than ARM. However, first work on getting the complete documentation for the debug access: that might or might not be a problem. when creating the new target, keep in mind that not all PowerPC chips are the same: there are different cores, and SOCs using different debug interfaces, so the structure should allow for these variations, even if the code only handles one such variant. > The idea is to use a debugger based on the FT2232 chip with a new > development board based on PPC device. Moreover, I'm looking for a > collaboration, so I am ready to provide some board with this device. The chip uses JTAG, so any JTAG adapter supported by OpenOCD *should* work. What is interesting is that they claim NEXUS compatibility for the debug interface, so there might be a chance to get documentation (the Freescale devices I work with use COP, and the documentation is quite closed). I work on MPC8314 and P1010 (Freescale), so I am afraid I won't be able to help much. cu Michael ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
