noise on power supply

[yojanse]

Hi, im working with a mcu rt1050 and im using a laboratory power supply , the problem is when i energy a electromagnetic lock with a separate power supply i get the noise over the source (check the picture) and it restart my mcu. 

Whats this error type ?

How can i solve it ?

i correct the error, the problem was the inductor load, i used a reverse diode

Hi,

Could you regenerate the same behavior with RT1050 Evaluation board (MIMXRT1050-EVKB) ?

I would recommend customer to refer <MIMXRT105060HDUG> document about power circuit design for RT1050 chip.

Wish it helps.
