MIMXRT1064EVK "0 available SWD Devices detected" issue

balasundaram — Mon, 01 Jul 2024 07:38:24 GMT

After the build, when I try to connect via debugging, IDE shows me the "0 available SWD Devices detected" error, and I tried the following steps to resolve it. But after following these steps it still shows the same error that "0 available SWD Devices detected".

You need to modify SW7 switch configuration in the NXP board

Switch SW7: 0010 --> 0001
Reboot the board and download the program
After successful download, reset the switch back to its original position
Reboot the board again, and that's it (Now you will be back to working state)
So, Please help me to resolve this.

Hi @balasundaram ,

Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.

Please try to use the MCUBootutility to connect your board in serial download mode.

You also need to find another USB cable to connect the J9.

https://github.com/JayHeng/NXP-MCUBootUtility/releases/tag/v6.2.0

the related user manual is:

After you connect the board, you can do the mass erase with the MCUBootutility:

You can use this method do the mass erase, then switch back to the internal boot mode, and try the SWD again.

BTW, you also need to check your board, make sure the power led is OK.

If you still have question about it, please kindly let me know.

Best Regards,

Kerry
