MIMXRT700-EVK - probe undetected error.

Nand_03 — Mon, 23 Mar 2026 06:38:41 GMT

Hi,

I am trying to fix the Board probe detection issue on Windows. After connecting the new board to Windows laptop, it got detected as USB Composite Device and VS Code / gui guider failed to see the target board for programming example projects.

To fix the Probe undetected issue, tried the following but the issue persists:

(1) Force updated board firmware using MCU-Link (with the board in ISP mode) and installed CMSIS-DAP drivers manually

-> Windows still continues to choose its own drivers for the board and fails to see the board as CMSIS-DAP device

(2) Tried NXP MCU boot utility but couldn’t complete loading the image due to one of the below errors:

(a) Please configure boot device in Flashloader first!

- Not clear why above error (a) occurs even after using correct configuration details for the Octal Flash in the NXP boot utility app.

(b) Make sure you have put MCU in ISP (In-System Programming) modes (ISP[2:0] pins = 3’b010 (USB) or 3’b110 (UART)!

- MIMXRT700-EVK only have 2 bits for SW10 and 1-bit for Sw11. To enter ISP mode, SW10 needs to be set to 10 and SW11 -> 0. So error (b) doesn’t seem to make sense.

i tried above workarounds on 3 different Windows laptops and all experience same issues.

It will be very helpful if someone could help check and advise next steps.

Best Regards,

Hi @Nand_03 ,

Thanks for reaching out!

Will you please try to use MCU ISP mode with the latest MCUXpresso Secure Provisioning Tool ? I tested with RT700-EVK on my side, it could work with both uart port and usb port.

Best regards,
Gavin

Hi Gavin,

Thanks for the reply. I tried using MCUXpresso secure provisioning tool today to force program the EVK board in ISP Mode (SW10 -> 10 & SW11 -> 0) but noticed the COM port on laptop to which the board J54 is connected, is not detected. For baudrate I chose 115200. Even before the communication is established between the EVK board and the laptop, the “Write Image” action fails due to USB undetected issue.

Is there a way to resolve the usb/probe detection issue?

Best Regards,
