Fdma.ko insmod failed

[435761040]

My environment is:
BSP19.0
Kernel v4.14.34_bsp19.0
Vsdk RTM 1.3

After loading fdma.ko is the following error popping up?

How to fix? Is there a patch?

Hi, 

what is your EVB? Are you using Debian or Yocto?  I just tried remove/insert again fdma on S32V234_SBC with Yocto - and there is no issue.

I am Manually building Linux BSP components

[435761040]

This is my current kernel

Linux s32v234sbc 4.14.34-rt27-dirty #2 SMP Thu Feb 14 12:22:27 CST 2019 aarch64 aarch64 aarch64 GNU/Linux

What is your environment? I used bsp17.0S before to use Insmod fdma
But bsp19.0 has this problem
I saw on other posts that I can support VSDK through the patch kernel?

0001-s32v234-dts-Add-VSDK-specific-configuration.patch

Where is this patch obtained? Finally, I would like to ask which branch of linux bsp19.0 corresponds to git?

Thank you

Hi, 

the patch is part of VSDK installation - located in [YOUR_VSDK_INSTALL_PATH]/s32v234_sdk/os/linux/

I'm using pre-build SD card image with Yocto linux. This image contains all configurations. You can get this image here:

Yes, the problem is solved after the patch is finished.
But reported when applying vsdk demo
Bus error .
I can determine if it is a kernel or a device tree.

My kernel is

Linux s32v234sbc 4.14.34-rt27-00002-g12135f4-dirty #4 SMP Fri Feb 15 10:07:37 CST 2019 aarch64 aarch64 aarch64 GNU/Linux

What I want to ask is, which is the bsp19.0 kernel branch corresponding to vsdk1.3?
According to the manual I git clone https://source.co deaurora.org/external/autobsps32/linux
Get the kernel of bsp19.0
But which branch of the branch corresponds to vsdk1.3?

Thank

Hi,

The prebuild SD card image uses kernel: 

Linux s32v234sbc 4.14.34-rt27+g3b93d42 #1 SMP Tue Dec 4 16:37:13 EET 2018 aarch64 aarch64 aarch64 GNU/Linux

Anyway, it is hard to say what else may be wrong. For me are all VSDK examples working without any issue.
