I changed the BDM to a P&E Multilink12 parallel BDM instead of my USB
BDM, and the all three target's program fine. I can understand that my E128 does not have a problem as its said to have a better BDM interface, but it is strange that the older EVB seems ok, but not to worry. I will now need to get another BDM interface cable. Andrew Andrew Lohmann wrote: > Taggart6 > I think the settings are fine, Cosmic have looked at the Zap connect, > linker and map file for me.
