Transferring data from SD-Card of ZYBO to DDR and then from DDR to PL of ZYBO
Sami Malik posted a question in FPGA
I am working on a project in which i have to transfer .txt file from SD-Card to DDR and then from DDR to PL of ZYBO. I'm a beginner on ZYBO and don't know how to perform it. Please help me out with this problem... -
unable to Transfer more then 32bits from PS to PL through BRAM of Zybo
Sami Malik posted a question in FPGA
Hi, Currently I'm working on a project in which I want to transfer 1MB data from PS to PL using BRAM using custom IP. I receive correct data at PL whenever I send data less then 32 bits from PS to PL but when I send more bits from PS, I'm unable to receive even a single bit. is there any clock issue as I'm using clock of PS for my custom IP or their is any other problem? Regards, Sami -
I'm working on Data compression so studying different code techniques such as follows to implement on zybo board Golomb coding special case Rice code compression Huffman code Arithmetic code And finally Dynamic Markov compression I selected DMC because it is dynamic in nature and work well with sensor (as input).Here is the problem that i don't know exactly markov compression is good for this or not. Also when i study the DMC it's algorithm is similar to sequence detector (so are they same?). Secondly in video processing/image processing or in general which tech. Is used in Data compression.

Hi, I am working on a project in which i am using Pmod Bt2. Once i have connected Pmod BT2 with Arduino and give it 5 voltage and ground then after few minutes Pmod BT2 turn off and Now it's not turning on. What is the problem with it ? Is it burn due to 5 voltage or what happened with it? Regards, AQ

Hi I made a block design in which I have connected BRAM with PS in vivado 2014.4. Then I created hdl wrapper and then generated an output product and then generated a bit stream and then exported it to sdk. But when I opened it in sdk my .hdf file is updated correctly but in bsp file, xparameters.h is not getting update and showing me wrong values of base and high address of my BRAM. In vivado base address of axi_bram_ctrl_0 is 0x40000000 but xparameters.h in sdk is showing me 0x00000000. Screenshot of addresses is attached. I have repeat the whole process of making a block in new project and exporting it to sdk but nothing changed. Regards,

Hi, I am sending data '0' and '1' from Arduino through HC05 bluetooth module and receiving that data ('0' and '1') on PMOD BT2 which is connected on the XADC(JA) port of Zybo. Once the arduino sends the data ('0' and '1') the "RX" pin on Arduino UNO blink and when this data is received at PMOD BT2 the 'TX' pin on the PMOD BT2 blink. I want to ON and OFF the LED on the base of this '0' and '1'. But the PROBLEM is that the LED is blinking when the TX pin on PMOD BT2 is blinking while receiving 0 and 1, it is following the blinking of 'TX' on PMOD BT2 instead of the data (0 and 1). How can i access that data ('0' or '1') in some register to use it for LED ON and OFF? Is there any option to store that data which i am receiving on PMOD BT2? How can i store that data which i am receiving on PMOD BT2? The Code which i am running on Arduino is Here for sending 0 and 1 continuously and the Verilog code which i am using to blink the LED is Here. The Master File Is also attached Here . Please check these code and guide me. *I have tested on Arduino that the data is receiving properly which is 0 and 1. Regards, AQ -
Hi, I have made the block diagram of BRAM and populate it from PS section of Zybo. I have made the PORTB of BRAM as external. Now I want to read this BRAM from PL section but I don't know how to read it using verilog code. Do I have to make changes in design_wrapper.v of my block diagram and then I have to do some instantiation in my main.v or there is any other method to do so? Regards, Sami

Hi, I am working on a project in which i want to send signal from Arduino board to Zybo . For this purpose i want to connect the HC05 with Pmod BT2. I go through from Pmod BT2 reference manual but i did not find any thing which is used to configure Pmod as master slave. Kindly tell me how to configure Pmod as master or slave while dealing with HC05 with Arduino?

Hi, I am working on a project in which i am receiving a signal from a sensor. I transmit this signal to Pmod BT2 of Zybo from arduino board. I am receiving this signal on SDK of Xilinx and i want to transfer this signal to Programming Logic part (PL) of zybo. What will be the procedure to send this signal to PL from Pmod BT2?. What Changes i should made in my verilog code to transfer this signal to Programming Logic(PL) part of Zybo. Thanks,

I am trying to use the Pmod I2C Interface with Zynq Zedboard with I2C Interface. And, I have completed the bitstream generation. But while doing the SDK portion and running the main.c file, it is not giving any output as given in this thread. I this thread you have replied as "I have attached a generic IIC IP core named PmodACL. You will need to alter the PmodACL.h , PmodACL.c and the main.c using the Pmod TMP3 and the datasheet here as a reference." Can you provide the altered code as I am not able to understand what are the alterations required? Here, I am attaching the link of the thread. Please help me regarding this ASAP. This is the source which I am following. https://forum.digilentinc.com/topic/5301-pmodacl-i2c-zedboard-getting-started-with-digilent-pmod-ips/ -
Hello, I want to connect USB keyboard to Zynq Zybo board. But it takes USB OTG as input. I previously had a code which included ps2data and ps2clk signals. I am not sure about how to do this interface with Zybo board. Any help will be appreciated ! Thanks, Rohit
