USB-ML-12 (USB BDM Multilink) is not working

[vigneshkumarp]

As we are using The USB-ML-12 (USB BDM Multilink) for programming the controller, one of the multilink is not working right now but the other one is working fine.

While we connect to the USB without host processor board the YELLOW led is glowing not the BLUE. When we connect to the target processor it remains the same i.e., only YELLOW led glows. We have updated the drivers, uninstalled the drivers and installed again but it doesn't works out. Is there any problem with hardware?? If so how can we identify it??

Thanks in advance...

Hello ,

- From the technical summary document , we know the two light function :

http://www.pemicro.com/downloads/tech_summary/usb-ml-12%20tech%20summary%201.05.pdf  

So i think your PC have not detect the USB Mutilink debugger interface .

- What the version of your debugger, and what system of your PC ?

If the debugger is REV.A , it not supported the newest operating system .

Hope it helps
