I'm testing it using stm32 module. 8970203F is the JTAG_ID of Mega128(0x9702 stands for Mega128). But after this ID, all TDO will be '1'. AVR will not output TDI value after JTAG_ID, it will output all '1' instead. 2009-04-25 Best Regards, Simon Qian SimonQian(simonq...@simonqian.com) ---- www.SimonQian.com
