I am a grad student working on TMSC6202. And I design a 6202 PCB. The
PCB can not work. The main problem is the JTAG can not work correctly.
I use ALVC16245 as JTAG buffer. And I use pullup resistance on EMU0(pin 13),
EMU1(pin 14),TMS(pin 1),TDI(pin 3),TDO(pin 7). The resistance is 4.7K. When I
the ccs(ccs2.1),sometimes it can run with no error report,but it can not work.
sometimes (mostly) ccs will report error.
The attached file is the schematic diagram. Thanks a lot.
