The real quick answer is that for some reason you're receiving all-ones (0x1f) back from a JTAG scan while switching to another scan chain ... when the chip is required to return a different value (0x10). I'd guess it's trying to read a register like DSCR, polling for status changes, but that's just a guess at this point. Now, that version you're using isn't all that old, and I don't think anything much has changed since then in that area, but you should try this with the latest code. Also, try to get us more information by posting a "debug_level 3" log. - Dave _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
