First of all, I doubt anyone will actually want to try to debug that mess. Second, this is something that only happens in the chip we have. Any future project would use a different CPU (the 2442 is getting old, the MCP we have doesn't have enough RAM, and it's only SDR to start with.) I wouldn't worry about the cost of adding 0Rs (which is near-zero), but about adding a lot more components to the board, making it more crowded. Again, please don't try to over-optimize the gta02-core design for longevity. That's not what it's for. The more time we spend fussing over minor details, the longer it will take until we get a chance to get our hands on something we really want. - Werner _______________________________________________ gta02-core mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/gta02-core
