I tried before looking at the firmware and hex edit a new serial number. Most of the clone ones probably have one of 2 serial numbers that are blacklisted. See if it helps.I can see firmware dated Jok, and later ones do brick. I know, that this is not the same problem, but try to disconnect your J-Lnik, when you know your not using it. So I just pull out the cable and I put it back the very same cable to the very same USB Port as it was and it works again. It's just cannot be found as if it isn't even connected by the USB cable. It's not that the firmware got deleted or "USB Device Not Recognized". I'm not using my J-link to that extend as you, but there are times, when I'm using from moring to early night (from ~7AM-7-8PM) and when I know, that I won't be using it (for eaxmple at night) I disconnect it from the PC.įrom time to time I forgot this and when I power on the PC while it's plugged and at those times the PC just can't see my J-Link. I'm using a J-link Clone too and I'm using the same firmware and from time to time I face something similar to your problem. So, for every flashing or debug session, two additional popups and few seconds delay, which is very annoying. However if I don't update it, it always asks me twice (two popups!) when I try to use it. J-Link GDB Server also updated the clone and it was working OK.īut this is not the case with the latest GDB Server version - when it updates the clone it instantly bricks/erases it. This ~24h timeout was the same irrespective of the serial number (I also tried original serial number from faculty). I then use files from posted by Crackn (thank you) to fix it and then it is working again. When I reattach them Windows says "USB Device Not Recognized" because they have VID/PID 0. I have two J-Link clones and basically they work OK, but every ~24 hours (they are attached to the PC all the time) they stop responding.
