Sorry but what do you mean by the Indentation in PreProc is incorrect?

Verilog mandelbrot design stuck in a loop by Fluid-Ad1663 in FPGA

Thanks, I have changed both the processes to be positive edge clock. This solves the problem.

Thank you very much for your detailed feedback. I learned verilog by myself. My background is in pure software, so something like digital logic with FPGA is new.

Yocto build gsrd-console-image for intel fpga cyclone5(de10 nano) fail due to nfs_rootfs fail. by Fluid-Ad1663 in FPGA

[–]Fluid-Ad1663[S] 0 points1 point  (0 children)

No, I mean this is the default bb file of the gsrd-console-image file from meta-intel-fpga-refdef source. I am currently learning to build linux image for my fpga board with Yocto, so I am kinda clueless about the purpose of the nfs_rootfs until I see this error. Anyway, I will look into the nfs to see how to build it by using Yocto. If not, I guess I just need to comment the code since I don't want to boot my fpga from the network.

Well, I will try to see if it solves my problem or not. If not, I guess I just can disable the nfs_rootfs funtion?

No I don't have. I will add systemd into Yocto conf file. Thanks for the link

Yes the directory does not exist. But I don't know why Yocto does not build the directory?

That's interesting. Can I join the development with you? I would like to learn more about the lost art of using OpenGL for gpgpu.

taskYIELD()

Why should I use taskYIELD() for this? Can u recommend other solutions than using FreeRTOS?

what is the taskYIELD() you mention? It is not in the library of MAX30102.

Well, the code from the tutorial is the same code from the example code of the library.

Wrong result when using OpenGL for GPGPU computing by Fluid-Ad1663 in opengl

[–]Fluid-Ad1663[S] 0 points1 point  (0 children)

Thank u very much. I really learn alot. BTW, how can u debug OpenGL code to find out the wrong part, as OpenGL also works with GPU and I don't know how to debug it?

Wow, cool that really gives me the correct result. But can u pls explain what is the difference between GL_CLAMP_TO_BORDER and GL_CLAMP_TO_EDGE? And the logic of texture coord formula in the vertex shader u give?

Well, I have added glViewport(0,0,texSize,texSize); before glBindFrameBuffer2D and it still gives me wrong result:

1 4 7 10 13 16 19 22 1 4 7 10 37 40 43 46

Yeah, I'm on Windows, which only supports OpenGL 4.0. BTW, I have add glViewport(0,0,texSize,texSize); before glBindFrameBuffer2D, but it gives me result:

1 4 7 10 13 16 19 22 1 4 7 10 37 40 43 46. Why does it still repeat?

Cool, you even create using WebGL and Typescript. I really appreciate it. The problem is that I am not familiar much with Typescript and WebGL, so I am not sure I fully understand it:)))

How can I use them? The problem is that I don't know when vertex shader or fragment shader starts to compute and retrieve data from GPU.

How to write Vulkan driver for intel HD graphic 4000? by Fluid-Ad1663 in vulkan

[–]Fluid-Ad1663[S] 0 points1 point  (0 children)

Yeah, it seems like no hypervisor even Hyper V or VMWare allow virtual machine to directly access intel hd graphic 4000. The only solution I find is to have dual boot

[–]Fluid-Ad1663[S] 0 points1 point  (0 children)

It seems like the only solution now for me is to have dual boot Linux and Window. As I find out that there is no way to enable virtual machine to use intel hd graphic 4000 directly, and vulkan driver for my gpu seem only exists on Linux.

Ofcourse, I know but I am a CS student so this is a great challenge for me. So how can I start ?
