SEC tool Connection Error

[Vishwajeetlohar]

Hii,

I am trying to use SEC tool for IMXRT1064 but it I am not able to establish the connection properly.

Please let me know if any changes or settings are required

Hi @Vishwajeetlohar 

I see that the tool is not being able to establish communication with the RT1064's USB port. Do you need to use USB? or you could also use UART? 

I recommend first checking if the MCU is on serial downloader mode. A simple way to do this is by reading the program counter with SWD debug, you must see and address like 0x2xxxx.
