I'm having problems connecting CCSV6 beta to our prototype board with a TMS570LS3137PGE on board. The board has its own XDS100v2 emulator, the circuit for which was copied from the USB Stick circuit. I programmed the FTDI device with a configuration from FTDI's own web site, but the result I got was this:
Error connecting to the target:
(Error -183 @ 0x0)
The controller has detected a cable break far-from itself.
The user must connect the cable/pod to the target.
(Emulation package 5.1.440.0)
From what I seen on another thread the only 5 lines needed to establish communications are:
TRST, TDI, TDO, TCK & TMS.
all appear to be present and connected.
Having failed to get this working we bought a Blackhawk USB100v2 emulator. Our prototype board has the option to jumper out the on-board emulator and connect directly via a 20 way header. This also fails, but with a different error message:
Error connecting to the target:
(Error -180 @ 0x0)
The controller has detected a target power loss.
The user must turn-on or connect the power supply for the target.
(Emulation package 5.1.440.0)
As all power supplies appear to be correct we're at a loss as to how to go forward.
Any clues you can give me as to what it's looking for when it generates these error messages would be greatly appreciated.
