Reset K3 led continuous toggling

[ESAKKI_MBD]

Hello nxp team,

We are working with S32K344HMS Rev B board and S32K344EHVPBS Rev A board.

while dumping the code via Matlab we are encountering one issue with rev b board i.e., the same program uploaded into both rev b and rev a board, but the reset k3 led is continuous toggling on and off only in rev b board not in rev a board.

And we tried with the example projects given by nxp team, the issue is not resolved.

what is the issue for reset led toggling in rev b board?

kindly help us to resolve this issue.

Hello @ESAKKI_MBD,

What is the exact part number / schematic number of the S32K344HMS Rev B board?

I would need to have all the jumper positions too.

BR, Daniel

Hello @danielmartynek 

Thanks for replying,

I have attached the photo of the S32K344HMS Rev B1 board with this post for your reference.

And we are working in dio configuration using MBDT with S32K344 EVB Rev B1.

while deploying the code using MATLAB we are able to see the functionality working but after some time like 3 to 5 sec the board reset LED starts blinking continuously.

Unable to find the solution.

Attached the project folder with this, kindly do some needful.

Thanks & Regards,

Esakki

Thanks Esakki,

Hard to say, it is runtime error since it occurs after 3-5 sec.

Can you read the MC_RGM_DES and MC_RGM_FES registers at the beginning of main() to get the source of the reset?
