Embedded Projects Forum (Open-Source Hardware)

Hi,

I like work a little with usbprog  and with the EVK1104 evaluation board. ( AT32UC3A3256 )
I wonder why usbprog jtagicemk2klon and usbprogAVR32 require different cables to an AVR JTAG connector.
Does this make sense or is this just grown historically?
Is there any place for a general description which pins should be connected ?
I know usbprogAVR32 does not support the flash devices.

My last low level hardware tries are "ages" ago.
Should it be possible to do some debug with jtagicemk2klon and EVK1104?
Where should I connect JP2-2 to ?

Can somebody confirm this cabling for jtagicemk2klon <=> JTAG10PIN ?
usbprog           JTAG10PIN
           1  <=> 3 (TDO)
           2  <=> 4 (VTref) JP2 -2 with ??
           3  <=>     
           4  <=> 5 (TMS)
           5  <=>
           6  <=>
           7  <=> 1 (TCK)
           8  <=> 6 (RST)
           9  <=> 9 (TDI)
         10  <=> 2/10 (GND)
         NC <=> 8 NC
         NC <=> 7  (EVTO, Event output, not used)

The cabling USBprogAVR32 to Grasshopper is described here:

Have a nice day,
