Thank you for your concise tutorial. I tested it on my BASYS3 and it worked!. at first I had problem running the bitstream then I read a comment below and I re-run the clock wizard and I selected single clock and then it worked!. Great step by step tutorial and very helpful for me as a newbie to FPGA. I am now subscribed and looking forward to more videos 🙂

Good to hear! I ordered a Basys3 and while waiting for arrival I'm working with Vivado 2022.2 and 2018.3. I hope to get the Microblaze working on one of these. I'm using the Webpack version.

Thank you for walking us through Vitis.

Excellent tutorial. I watched your video on the SDK also. I have Vivado 2022.2 and 2018.3 (Webpack versions) and hope to get one of those running the MicroBlaze code.

Very nicely explained. You rock!

Hi @Let's Learn I was using bittware board, after adding the clocking circuit, the error resolved. But currently after creating the hello world, not getting serial logs. I am using Linux, ttyUSB1 is present. What might be the issue?

Hello :) I have a design with microblaze and my ip (arty s7) , and i want to implement FreeRTOS OS in vitis 2020.2. Unfortunately Vitis scream that he can't generate bsp files. Any suggestions?

Hello ! I could generate the Bitstream Successfully, I could also Export the Hardware and generate the Vitis Projects as per the steps mentioned in your video. I'm using TeraTerm as well. But on my TeraTerm window, I'm just getting a random UART Character. The Baudrate is 9600. Please help with the same.

Hello. I am using Arty-A7 Digilent board. after i run the program i get: Error while launching program: Cannot reset MicroBlaze #0. Cannot stop MicroBlaze. MicroBlaze is held in reset

Hi, As I follow your steps to implement this. But Hello world messages didn't show on the UART port. Does urat port need to open manually?

Can't you run a terminal from within the Vitis?

Hello sir,thanks for the video,how to work with lwip tcp server client application on same machine vitis in qemu emulator?if possible please tell us the procedure.

Super very helpful

Hi, i really like your videos, they're very helpful. I'd like to know if you know how to use the Artix Spi bus to communicate with external composants using MicroBlaze processor. I don't know how to start with that. Thank you so much!

I have used a SPI flash with microblaze on artix. It did work. You can try adding AXI Quad SPI module in your block design and then address the peripheral using the axi address range assigned. Remember to configure the axi quad spi IP as per your peripheral.

I have just the thing for you. Download their PMOD IPs. One of them is for the OLED. You need to add this to your project repository. When you install the JA connector you'll see many options. You will want to load the OLED IP. It's an SPI device. When you export to SDK, you'll see example code to run it. From that you can teach yourself everything you need to use the SPI bus. You can ignore the code you don't need for the display.

Hi, I tried your procedure on a Nexsys A7 board with an Artix-7 FPGA. The generate bitstream failed due to errors regarding the differential clock and reset_0. How did you work around this?

@letslearn39

3 жыл бұрын

Please check whether Nexsys board has a differential clock on the board. IF its not available you can reconfigure the Clocking Wizard IP in your design to take a single ended input. Connection automation should automatically map the board clock to this single ended input. Similar could be the problem with reset. You can manually map it to any of the switches on the board. Be sure about the polarity of the reset line.

I do not find a constraint file in your project. Do not you need to assign pins? I try to ignore the pin assignment, but Vivado return errors when doing synthesis.

@letslearn39

3 жыл бұрын

If you are using AC-701 board you dont need to create any constraint file as the the pins are already defined in the board files. If you are using custom board you have to create your own constraint file.

Hello @Let's Learm, did you add any constraint file or xdc file in your program? Cause your video looks like compiling successfully without physical constraints.

@letslearn39

3 жыл бұрын

Since I am using AC701 board from Xilinx in this demo, the board constraint files are automatically taken by vivado. You need not add anything manually. If you are using a custom board, you will have to add the constraints manually.

​@@letslearn39 I simulate exactly the same project like you and launch it on Vitis. However, after building: 1. The Platform, it receive to many errors informing me, they are too many Header files like Xil_printf.h, xil_io.h, ...etc missing in the include folder of the platform under bsp folder. I found all those headers files and add it the include folder. I rebuilt the platform and it works. I've the process like this each time, i'll like to create a platform for a new xsa.file. Now, my questions: Did you face to the same situation before uploading the video? 2. The application, many failures have occurred: -> undefined reference to 'out byte'. Solution: for this i had to comment the line xil_printf("Hello World"); -> undefined reference to 'microblaze_enable_dcache'. Solution: i had to comment also the line in platform.c -> undefined reference to 'microblaze_enable_icache'. Solution: i had to comment also the line in platform.c -> undefined reference to '_interrupt_handler' in function '_vector_interrupt'. ==> At this stage found no solution up to now :-( . Do you please have any idea, how i can solve this issue? Thanks in advance!
