Use J-link to debug RT1050 without EVB.

[JackyPeng]

Hi all,

Recently, I want debug the RT1050 with J-link without EVB. I put the RT1050 device into the socket and  the J-link probe connect directly to the device pins. The device is powered on. But when I use J-link software "J-link commend" to connect the device. Prompt that it can't find the RT1050 device.

I can not find where the problem is, is there something wrong with my hard link?  Or do RT1050 device need to boot from internal rom? Or does it require an external crystal oscillator? 

Any comments would be  greatly appreciated.

Hi @JackyPeng ,

Of course it need crystal oscillator. It's a must. After you attach the crystal you can set the chip to serial download mode then try to connect it by NXP-MCUBootUtility via uart or usb. If it can connect, that means RT1050 runs good.
