SDK Examples for ADC do not execute on MCIMX8DXL-WEVK

[chanks]

I'm unable to run the LPADC examples from the MIMX8DXL EVK.  Both the polling and interrupt driven examples seem to crash at the LPADC_Init call.

The interrupt example prints the following and then nothing else:
LPADC Interrupt Example

Do these examples work on the evaluation board?  If so, is there any additional setup needed?

Dunno if you ever solved this, but for anyone else that may have run into this on 6.1.1 on a dxl, I was able to solve this by modifying the SCFW to transfer the SC_R_ADC_0 resource to the m4 partition and as well as the SC_P_ADC_IN0 - SC_P_ADC_IN5 in the board.c file by adding them to the rsrc_list and the pad_list.

Hello,

If you are in linux 6.1 BSP is should be working, now if you are on previous version you have to add the following:

Should the M4 ADC examples work without any reconfiguration? I am running Linux 6.1.1 on the primary cores.

Sorry I forgot to clarify that I was running the examples for the MCU.  I'm running Linux 6.1.1 for the eval board which I downloaded from the NXP website.  I'm trying to launch the MCU examples using the remoteproc interface and it's failing.
