Maybe for i.MX27 ... having a separate TAP for boundary scan seems unusual to me. ISTR that most ARM cores are set up so that they have an integrator-provided scan chain (plus the EmbeddedICE, maybe an ETM, etc), conventionally for boundary scan. And several TI chips have their boundary scan hanging off the IcePICK, a.k.a. "JTAG Routing Controller" (JRC), so it's accessible even when the various ARM and DSP cores aren't switched into the scan chain. Re how to do it ... I'd kind of hope that a key step would be throwing a BSDL file into the OpenOCD config, since making *use* of the boundary scan involves info that's in that file. Example, knowing which registers to use, how big they are, what the bit semantics are, what instruction opcodes are involved, etc. - Dave _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
