I had build the open embedded image by editing the local.conf file and adding KERNEL_MODULE_AUTOLOAD += "vf610_cm4_rproc. But how can I manually add vf610_cm4_rproc.conf file in ‘/etc/modules-load.d/’ . The cat command used in that website shows an error “cat: can’t open ‘/etc/modules-load.d/vf610_cm4_rproc.conf’: No such file or diry”. How to solve this problem?
hi sreemadhav
the cat command is to show the output of a file on standard output. For creating files you should use
echo "the text you want to write" > filename , or you can use vi editor.
no, you have manually add the file to the /etc/modules-load.d/ folder
did you reboot, after creating the link with ln -s hello_world.elf freertos-rpmsg.elf
hi @jaski.tx
Okay. But while build the image using OpenEmbedded, vf610_cm4_rproc.conf seems to have created in the image. But here there is no such file. why is it so?
Hi @jaski.tx
After adding as per the command " echo vf610_cm4_rproc > vf610_cm4_rproc.conf " the cat command works and vf610_cm4_rproc file is created in /etc/modules-load.d/vf610_cm4_rproc.conf. Then I had done the following commands:
cd /lib/firmware/
ln -s hello_world.elf freertos-rpmsg.elf
which was completed. Then on typing the command dmesg|grep remoteproc nothing is happening. ie, it doesn’t shows any further results. Can you please explain why is it so?
It really should load the firmware at this point. What version of the BSP are you using exactly? Can you please provide the complete output of dmesg?

I’m using LinuxImage2.6
Here attached the screen shot of message received on typing dmesg and dmesg|grep remoteproc
Your dmesg output looks ok.
Can you try manually loading vf610_cm4_rproc using modeprobe?
modeprobe vf610_cm4_rproc
Which 2.6 release are you using exactly? There are multiple versions…
Note that 2.6 only has been released as a Beta. We recommend to use our latest stable release (2.7) with bootaux as boot method.
hi @stefan.tx
I’m using BSP image v2.6. How can I update it to v2.6.1? Is 2.6.1 necessary to load the remoterproc for freertos
you should use bsp 2.7, as it is a stable release which is supported.
remoteproc is not well loaded. Try typing dmesg | grep proc and send the log as text.
