My JLINK light turns green and the device is not recognized [Copy link]

 

My JLINK worked fine a few days ago, but when I plugged it in today, the light suddenly turned green, the chip could not be recognized, and the computer could not recognize the device.

I searched for solutions online and erased it first. Anyway, after a series of operations, it was time to burn the firmware.

The document I found said that after opening the flashing software and setting it up, plugging in the USB cable, the flashing option will become available.

But my computer didn't work.

As shown below:

Can someone tell me if my JLINK is broken? Thanks!

Jlink, I've had the problem of firmware failure when using jlink11 before. I have the corresponding recovery tool here

If the green light is on all the time, it seems that JLink is not running. Try reinstalling the JLink driver, make sure there is no problem on the computer, and then look for the Link problem.

Thanks! Reinstalling doesn't work.

The chip of my JLINK is AT91SAM7564AU.

The SAM-BA software cannot find the corresponding chip.

Dear moderator, you have started using v11 so early, you must have a lot of money at home!

Cross-testing can be done by trying other computers and other software codes. Non-engineering mode can only be determined by cross-testing.

The company bought them all. Some chips really can't be adjusted. They can only be upgraded, but they are all pirated.

The day before yesterday, I spent 300 yuan to adjust the touch screen of Renesas. The tools are quite expensive.

Renesas' new RAM microcontroller uses the M33 core. I have one but the firmware has been lost. The genuine one costs more than 2,000 yuan.

Done.
