I want to use ADVM as the analog frontend in my design and have trouble getting video data in to the Zynq Ultrascale module. My device tree is as follows. How do I even set the analog input port? Can deinterlacing be enabled through the linux driver? The question is a bit complicated to answer here, because you are using Xilinx tools and Linux V4L. Sorry but I can't figure out from your message what's the current problem you're getting now.
A way to have very low level access to registers is through debugfs regmap. Log in. Site Search Log in. Linux Software Drivers.

Hi, Sorry but I can't figure out from your message what's the current problem you're getting now. Hey, The driver was not written by, but we do offer support for it. I've asked a colleague to look into this more closely.
Is it correct? I'm new on Linux, and probably my question is dummy: what are the involved files to build the kernel module of the AD? Further, the ". Can I use the same method to initialize the AD also if I will implement a kernel module? Regarding the device trees question.
Linux kernel modules and open firmware device tress are two separate things, they are not related and don't influence each other. So yes they work equally well. Some colleagues are working on a custom kernel, so Petalinux is only a mean to work on other task. I added successfully a kernel module in Petalinux Do I have to add kernel module with these files? Or the AD driver can work well without them? I have built a kernel module for AD using only the files for the SPI, but i got this message during the loading of the ko file.

Thanks and Regards. Reply Cancel Cancel. Hi, May I know why changing the kernel source is not an option? Not sure if a kernel module will help you in your situation. Modules are generally build from the same kernel, which they are loaded in. Hi, thanks for your reply. Hello Michael, I added successfully a kernel module in Petalinux What must I enable to perform it? Yes - there is a problem with your device tree. Looks like your reset-gpios is somehow using the phandle from a your clocks.
Is this issue related to the device tree?

Hi, Since this new question is kind of unrelated to the original one, I've split the thread. I'm not familiar with the Petalinux process, so I will let others comment on this. Thanks, Dragos.
The meta-adi Petalinux repo we provide is for reference and uses our Github repos. Will try to ping him when he gets back. Hi Sir : Thank you for your reply.
I should add AD drivers on Petalinux. I have created BOOT. The image created is working fine. I executed petalinux-config command. Selected Linux Components. I added external kernel by specifying the path where the folder downloaded from the above website is saved.
I selected auto config options and specified to add a manual device tree. The path for the same is from the kernel downloaded from the above website i. Later i executed petalinux-build command. I tried resolving this issue and created images, but when I executed the following command on the console using UART port:.
Can you please guide how to add AD drivers on petalinux because I am of the opinion that the steps I am following which I have mentioned in my above question may be incorrect. Log in.

Xilinx Linux is the most prevalent operating system used by Xilinx products. Xilinx products are supported by comprehensive set of open source resources to develop, boot, run, debug and maintain your Linux based application for a Xilinx SoC or emulation platform.
We offer example applications, Kernel configurations, Yocto recipes, Multiprocessing and Real-time solutions, device drivers and Linux open source developer will find familiar sources, tools, and support forums to learn, develop and interact with others of like interests, needs and passion.
Key factors in an RTOS are keeping it simple and light weight. Other factors are minimal interrupt latency and contact thread switching latency. An RTOS is valued more for how quickly and how deterministically it can respond than for the amount of complexity it can handle.
It is professionally developed, strictly quality controlled, robust, supported, and free to embed in commercial products without any requirement to expose your proprietary source code.

I found information about xvdma. I spent 2 days without succeed. My final solution is easy. I have working solution after 2 hours. How do you create this fd if there is only a physical address that I need to access? Can fd be NULL?
Does it mean that there must be a driver running already? Do I need to configure the device-tree file before I use the mmap? Function mmap maps physical addres to virtual adress space. You does not need instantiate any driver in device-tree, but is good idea to limit memory used by kernel to reserve physical memory for store data by DMA engine. Thanks, I spent more time reading a device driver book and I got to the same conclusion.
After that is like a bare metal driver. Another interesting way is to implement a small character driver that redefines the mmap to map it to a physical address. But I get a fragmentation issue when using kmalloc.
Hi Vatu, Can you please share the code that uses mmap to control the driver from user space? Thanks a lot for these tipps! I just tried the mmaped access to the dma. Unfortunately, when I try to read out the status register, it freezes the system.
My code is:. When I leave away the last print statement, it runs nicely.

Does anyone know what the problem could be? Hi Michael, Does it freez or you get a segmentation fault? You can use Xilinx example code for bare metal ADMA driver where you should change the base address to be your mmap virtual address. It freezes completely Linux. The same firmware though still freezes Linux. I will check if the addresses etc.
You have to make sure that the physical address you are mapping is not visible to Linux. In devicetree. For instance if you have MB you get:.
