  1. I connected an PmodACL2 to JB pmod connector in vivado and created new clock in the zynq (100Mhz) then I connected it to the SCLK in the PmodACL2 , but it apears that there are some problems , these are the warnings at the Tcl console (the bitstream is generated but I want to know if these will cause a problem later) : Firas
  2. hello I bought a new ZYBO board so no need to look for difficult solutions Now I have other problems. -I created a petalinux project and I imported the "hw" description then builded BOOT.BIN -GOAL : booting linux on ZYBO and recognizing all the GPIOS where I will plug (GYRO, Accelerometre,Bleutooth,Leds,Buttons) -assuming that the Devitree is well configured and contains all of the GPIOS , the Petalinux RG Manual contains lots of options but I dont see at any of the steps that I should put the Devicetree alongside with BOOT.BIN and linux image in the FAT32 partitio

  4. thank your for your offer it very nice from your part , and yeah , your number reflects your generosity toword peoples , but bout the accelerometre I dont think that it can not determine an object position and here is my explenaition ( based on my mathematics and physics background) acceleration is not the only variable that throught it we can for example determinate how much a robot made x meters in one of the thre axes (x,y,z) , the other variables that are missing are : - the periode of time T spent by
  5. @[email protected] Thank you but I prefer CMod A7 , it's more guaranty and sure Firas
  6. @[email protected] really ,, you where soo helpful , it's beyond working with a company , you did more then should , thank you for your help , you saved for me more than you imagine , and No it's not about promoting , you'r finding solutions so the Zybo and other digilent products become easier to manipulate . THANK YOU
  7. @[email protected] thank you for your fast reply , I tried to fix the Pmod problems but I failed it's a bit difficult , It's true that it looks like trying to fit a Square peg in a round hole , but I did not meant that that USBUART is the solution , I m just trying to know if there is a sort of a convertor interface from Accelerometre output to the UART port or the OGT port, is there any converters ?
  8. @[email protected] thank you ,, yeah all your messages are clear , I know that I can connect the Accelerometre directly to the PMOD connector on the zybo and then to the PC , BUT here is what I m doing so you'r going understand why I need the USBUART - I booted linux on the zybo so I should not use the PC even if I can , - I tried to connect the ACCELEROMETRE to the zybo throught the PMOD connectors , but it's not detected by the zybo , - after searching a lot and making lots of hardware diagnostics i found out that the PMOD connectors on the zybo are br
  9. @[email protected] thank you for the information , I m trying to connect a "Pmod ACL: 3-axis Accelerometer" to my zybo board throught a USB port (UART or OGT) , so I m looking for a solution , I found something that might help me wich is the "Pmod USBUART: USB to UART Interface" so i can plug the Accelerometre to the USBUART and then plug the USBUART into the ZYBO throught a USB port , can you guide me ?? , if what I m talking about is a solution , then is it the only one ? because I have to perchase the USBUART and that will take time. here is both the USBUART and the ACCELEROMETER . http
  10. hello , I have a linux ubuntu on my zybo board and I m going to use an accelerometre , So can I connect it throught UART USB instead of Gpio port ? please help
  11. I generate a bitstream and exported the heardware to SDK , and I m stack in this step "import the hardware configuration (.hdf) by following pg. 25 of RG. for petalinux" there are 3 .hdf files in my project and I tried them all , but it's always the same error : (Failed to locate the Vivado export to SDK directory, please make sure the directory directory exists! Configures the project or the specified component with menuconfig.) I m sure I imported the hardware in a good way ( see picture 1) picture (2,3,4) resume the my attempts using petalinuc-configure command wit
  12. @sbobrowicz I m soo happy that you deployed soo much time and effort to answer me , I will go back here as soon as I finich your instructions !
  13. HI @yohboy thank you for the link you shared , but I have problems generation DTS file with SDK , I m using the zybo-base-system-deseign provided in Digilent website , i will be soo happy if I can find a ready to implement DTS or DTB related to the zybo-base-system deseign..
  14. Hi @yohboy thank you , yes I have only one GPIO ,,, I m not working without Vivado , I think there is a relation between Vivado and DTS file but I choosed to work only with kernel drivers So I m looking forward to find a full DTS file and compile it so I can find all the drivers then I can controle all the peripheral leds buttons and Pmods !! Please I need help !!!! here is my DTS file : zynq-zybo.dts : /dts-v1/; / { #address-cells = <1>; #size-cells = <1>; compatible = "xlnx,zynq-7000"; model = "Xilinx Zynq"; alia
  15. I finished booting linux on zybo with linario file system and I m trying to user the user space and kernel drivers to controle LEDs and get input information from peripheral buttons , gyroscope, accéléromètre and a bluetooth So I wonder if I have to insert gpios déclarations in zynq-zybo.dts and compile a new devicetree.dtb !! this are some screanshots from my zybo terminal :
