Demo evkbmimxrt1170_rpmsg_lite_pingpong does not work.

[simmania]

I have the MIMXRT1170-EVK board. I installed the SDK_2.x_MIMXRT1170-EVKB. And imported the demo. The demo consists of the two subprojects:
evkbmimxrt1170_rpmsg_lite_pingpong_cm4
evkbmimxrt1170_rpmsg_lite_pingpong_cm7

I can compile it without errors. But when running (the cm7) I get the following error:

What am I doing wrong?

I created the SDK with SDK Builder and selected the evkmimxrt1170 board in stead of the evkbmimxrt1170 board. Now the demo works! Thanks.

Hi @simmania ,

I tested on my EVK with SDK_2_13_0_MIMXRT1170-EVK. It works fine. Please don't use EVKB SDK. Sometimes a slight difference will cause the demo can't run. 

Please also check if you have switch the board to serial download mode and erase the flash before debug.

This confuses me.

Firstly because an other NXP Techsupport told me to use the B version.
See https://community.nxp.com/t5/MCUXpresso-IDE/What-is-difference-between-evkmimxrt1170-and-evkbmimxrt1...

Secondly because the demo is part of the SDK, isn't it?

So the SDK_2.x_MIMXRT1170-EVK has its own demos and SDK_2.x_MIMXRT1170-EVKB also has its own demos.

I also found out that the evkbmemxrt1170_iled_blinky_cm4 does work, but the evkbmemxrt1170_iled_blinky_cm7 does not.

Hi @simmania ,

No, he is wrong. EVKB and EVK are different board although very similar. 

Please download sdk from https://mcuxpresso.nxp.com/en/welcome
