I found the bsdl file: http://www.avr32.ru/AP7000.bsdl In this file I find "attribute INSTRUCTION_LENGTH of AP7000: entity is 5;", so I guess I should use "-irlen 5". However, the openocd.pdf file is confusing while describing -ircapture and -irmask. Is -ircapture the JTAG opcode for the IDCODE command? Then 0x01 would be correct. However, openocd.pdf says "the ID code capture command". Not sure what this means. The same for "-irmask". openocd.pdf says "the corresponding mask for the ir register". That's quite elaborate. A mask for what? For what will it be used? Is it a mask for the result of the IDCODE command? Then probably it will used to mask away silicon version, right? The next thing that puzzles me is the boundary len. The BSDL file says "attribute BOUNDARY_LENGTH of AP7000: entity is 388", but I don't really know where to specify this. _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
