No USB connection to S32k144 EVB

Hello everyone,

I have bought the s32k144 EVB. I have the same problem like described here:
https://community.nxp.com/t5/S32K/Cannot-Connect-to-S32K144-Neither-FreeMaster-nor-S32DS/td-p/121244...
--> It seems that the normal RGB blinking SW is not flashed on the EVB. When first powering the EVB it should show the following function --> https://www.nxp.com/document/guide/get-started-with-the-s32k144evb:NGS-S32K144EVB

So, the RGB blinking LED I could not see only the green LEDs. I downloaded the zip file S32K144_EVB_JumpStart_Firmware.zip (from the first link) and put the srec file on the EVB via Windows.
The Board blinked with D2 and then showed the red led  D1 constantly shining. When I reset the board with the OnBoard button or when I switch off/on the Power Supply, the red light stays turned on.

Anyway, when I launch the FreeMASTER SW the connection WIzard shows the COM port correctly, but gives the error: No board detected on any of specified UART communication ports.
I activated 115200 and 9600 baud.
I think, this might be related to the red light.

Later on I realized, that the chip on my EVB is a K116. Does this affect anything?

Thank you for helping

Regards

 

EDIT 20210810: In case of anyone else having the same problem:

--> After checking the nxp site, I realized ... maybe I do not have received a k144 EVB (even it is written on the package) but a k116 EVB. Searching for help in the community, I found the following zip:
https://www.nxp.com/downloads/en/board-support-packages/S32K116EVB_JumpStart_FreeMaster.zip

--> When downloading the srec file (contained in the project within this zip, just search for it) onto the EVB, I see the LED blinking in RGB. It seems the board works fine. I am happy!
