In the MCU-Link pro Quick Start Guide, follow the steps for the firmware update and run the program_CMSIS.cmdj script in 1.2 of 3.
After running it prompts to set the board to ISP mode
But on top of the board I have the ISP jumper caps attached and it still reports an error.
The picture below is of my board
Hello @skylerc
1) I tested it using the same version of the script as you and there is no problem on my end:
2) Can you update it now with the person who lent it to you?
3) Try to connect with Flash Magic to confirm whether LPC55s69 has entered ISP mode. The following is an example of the ISP mode of the LPC55s69:

Hello @skylerc
May I ask where you bought the MCU-LINK PRO?

Hi @skylerc
Hello, there is no problem with the steps.
Change the USB cable and connector, connect the J4 jump cap first, then the USB cable, then open the software and try again.
If you still have problems, try another computer.
