Hi, regarding active serial mode:
I've now determined the meaning of all bits, including AS mode, in the simple protocol; it should be easy to add them in the code available from h**p://www.ixo.de/info/usb_jtag/. I'll do myself if I find the time... Maybe someone else can test AS? I hope there isn't more magic than I assume. I have no devices set up for AS mode here, so I can't actually test... JTAG however HAS been tested, I'm using it every day.
bit 0 in is tdo/conf_done,
bit 1 is dataout/nstatus.
bit 0 out is tck/dclk,
bit 1 out is tms/nconfig,
bit 2 out is nce,
bit 3 out is ncs,
bit 4 out is tdi/asdi/datao,
bit 5 out is led/output enable (has to be set to 1 for proper operation).
The meaning of bit 6 and bit 7 is described in the fx2/usbjtag.c in the zip from the above site. Furthermore I've uploaded experimental USB-Blaster drivers for openwince JTAG tools and OpenOCD there (work in progress).
