Motion link with 42688-P error message

By dreamy626gmailcom , 27 November 2024

Dear,

I'm trying to use motion link software with DK-42688P IMU sensor.

I successfully installed AtmelStudio and upload example codes on the board.
And I could see the sensor measurement using Putty.

When I tried to use motionLink software for visualization,
Flash MCU, connection, and select and config were successful.

But when I tried to power up the board using the button on the screen,
it keep saying "Object reference not set to an instance of an object" and nothing happen.

How can I solve this problem??
Should I use putty when I use motion link??

Thank you all in advance..!!

Hi,

You should not use Putty with MotionLink. I attached the MotionLink User Guide for your review.

I am running into the same issue.

Development board: DK-42688-V

I an not using putty, but I'm running into the same problem.
I can flash the FW on the MCU correctly, no issues there.
But once I try to initialize the board to start data capture, I get the same error: "Object reference not set to an instance of an object".

Any ideas on how I can get MotionLink to work? Thanks!

After flashing the MCU, please power cycle the device (disconnect the device completely from your PC). Then, connect it again with the cable and initialize the board.

Please look at the user guide above.

Hi, I have a DK-45605 and MotionLink 4.2.18 and have been having the same issue. I've followed the user guides posted by @MOD_Mustafa, and I've uninstalled and reinstalled all the relevant software and drivers and still have the same issue. I've also checked my jumper settings multiple times and they are correct.

The only ways I have gotten some signs of life are uploading various binaries with Microchip studio. In particular:
1. Uploading algo-agm-icm45605.bin results in communication via teraterm when I hit the reset button. I cannot get this communication if I flash the MCU via the motionlink software.
2. I also get PASS on selftests when uploading selftest-icm45605.bin.
3. I can get the device to dump tons of info uploading basic-read-registers-icm45605.bin
4. I can get the device to respond to inputs with adv-wom-icm45605.bin

I understand this is probably a weird windows thing. My questions to help further debug are:

1. Can someone explain the error message in a bit more detail so that we can try to debug it?
2. What binary or file is the motionlink software flashing when it tries to communicate with the DK board?
