regarding PE Micro Universal Multi-link

Hello , My question is regarding PE Micro Universal Multilink. We have developed a Board based on FRDMK64F. And using PE Micro multilink .. All of a sudden the Multilink has stopped working and no link on the USB led. What could be the reason and how to repair this issue. Any help will be greatly appreciated. I had only one PE Micro and our development is suffering. Also if there is a cheaper alternative to PE Micro Universal Multilink please suggest.

Hi Arati,

If you have Freedom Board with Segger OpenSDA Debug Firmware, it can be used to debug your custom board.
Have you try to update the firmware of USB Multilink? You can download "USB Multilink Universal (and FX) Resource CD" from PE micro.
Does this USB Multilink work on other computer?

Best Regards,

Robin

Hi Robin,

Thank you for your reply.. I am not directly the developer ... but I know in the original FRDMk64f board we were using segger for debug but in the Custom board that interface has been used for some other purpose.. though I am not 100% sure. We will try the firmware update also ..the issue itself is very strange ... if we disconnect the PE Micro multilink for a hour or so the USB light switches on for 1-2 mins and then again goes off .

Thanks again

Arati.

Hi Robin,

Sending you a photo of our custom Board,

But the problem is with the USB Multilink not the board .. because the USB led on the USB Multilink is not glowing anymore so it seems to be a power supply or some other h/w issue

Meanwhile I have written to PE Micro tech support also ..according to then it is some h/w issue on the USB ML..Hopefully they will also help us..

Thanks again
