HI How to port AD9364 driver to xilinx petalinux

You would need much more than that.

The easiest would be to use the ADI kernel (which is based off the Xilinx kernel tree) directly with petalinux.

You can follow the instructions here:

https://github.com/analogdevicesinc/meta-adi/tree/master/meta-adi-xilinx

Hi Michael,

Thanks for the very quick update. Let me try you solution. But We have to go with our exsting kernel and only we need to add the AD9364 driver alone. Is not possible with my aproach I have mentioned before. 

If it possible could you correct me what do I need to add extra bit.

Thanks,

Mahi

Here is a rebased patch set for AD936x on a vanilla xilinx-4.9  

https://github.com/analogdevicesinc/linux/commits/ad9361-xilinx-4.9

Some pieces in the IIO core might no longer been needed, depending on which kernel you're targeting.

Hi Michael,

I have planed for 5.10 Kernel and petalinux version 2021.2. Let me try

Thanks,

Mahi

Hi Michal,

I have followed above link you provided.I have one clarification. Below process for device tree addition to petalinux is correct?. I am using ZCU102 rev 1.0 reference board and AD-FMCOMMS-4 EBZ board

echo "KERNEL_DTB=\"pl-zynqmp-zcu102-rev10-ad9361-fmcomms2-3-overlay\"" >> project-spec/meta-user/conf/petalinuxbsp.conf

I have follwed below procedure. kindly have look and let me anything is wrong.

#This I have used 5.10 Kernel and petalinux version 2021.2
source <path-to-installed-PetaLinux>/settings.sh

petalinux-create -t project --template <PLATFORM> --name <PROJECT_NAME>, where <PLATFORM> is:
	* zynqMP (for UltraScale + MPSoC)

git clone github.com/.../meta-adi.git

cd <path-to-project>

# Check the Building HDL link below
petalinux-config --get-hw-description=<path to hdf file>
# Presently I am using the default .xsa file going forward I will used our custom created one.
#added below step
##Go to Yocto Settings->User layers and add the meta-adi-xilinx and meta-adi-core layers.

# Select the devicetree that fits the project being built
echo "KERNEL_DTB=\"${dts_to_use}\"" >> project-spec/meta-user/conf/petalinuxbsp.conf

cd build
petalinux-build


Thanks for your support. Much appreciated 
Thanks,
Mahi

Hi Mahi,

echo "KERNEL_DTB=\"pl-zynqmp-zcu102-rev10-ad9361-fmcomms2-3-overlay\"" >> project-spec/meta-user/conf/petalinuxbsp.conf

This looks suspicious... Do you want to use overlays? Have you selected that with 'petalinux-config'? 

i would also say that the devicetree you need to use is "zynqmp-zcu102-rev10-ad9364-fmcomms4.dts" which is not supported in meta-adi. That said, you need to follow this section of the README file.

On a last note, I see you're using petalinux 2021.2. Note that version is not supported and was never tested. You need to use 2021.1 with meta-adi otherwise we cannot give you full support on this.

Hi ,

Just changing the question bit now I have zc102 and ad9361 board. I have followed the below procedure from the below link. 

https://github.com/analogdevicesinc/meta-adi/tree/master/meta-adi-xilinx

source  <path-to-installed-PetaLinux>/settings.sh
petalinux-create -t project --template <PLATFORM> --name <PROJECT_NAME>, where <PLATFORM> is:
	* zynqMP (for UltraScale + MPSoC)
	* zynq (for Zynq)
	* microblaze (for MicroBlaze)

git clone https://github.com/analogdevicesinc/meta-adi.git

cd <path-to-project>

# Check the Building HDL link below
petalinux-config --get-hw-description=<path to hdf file>

# Select the devicetree that fits the project being built

echo "KERNEL_DTB=\"${zynqmp-zcu102-rev10-ad9361-fmcomms2-3}\"" >> project-spec/meta-user/conf/petalinuxbsp.conf

cd build
petalinux-build

I could see the below error

You could just do echo "KERNEL_DTB=\"zynqmp-zcu102-rev10-ad9361-fmcomms2-3\"" >> project-spec/meta-user/conf/petalinuxbsp.conf...

Are you still using petalinux 2021.2? Also make sure that you are using bash as your shell...
