    io_pin testing

    Hello All, I am using zynq 7000 customize board.In that a pin which is on bank 35 (FPGA) is taken on connector(j3).J3 connector is 7 pin connector in which 7 no. pin is ground. I am testing all io's by writing counter code. I am getting waveforms on DSO for all pins except 6 no. pin. I have added then chipscope .On chipscope i am getting the waveform but not on DSO. What can be the reason ?
  2. @Gra Thanks for your polite reply.. I can understand that it's not easy as we think.But everything is perfect expect the function execution. yes IN SPARTAN 3 PLB bus was there now AXI bus. but there is no solution to deal with it?
  3. @zygot zynq 7000 customize board.It's our customer application which was on spartan previously .Now the complete design has migrated to ZYNQ so I have the work to migrate the spartan design onto zynq.I can not modify their design .I have done it .problem I am facing regarding function execution
  4. Hello folks, I am working on zynq 7000 board in which artix 7 fpga is there.In the old design spartan 3 was used. I am working on migration from ISE 8.1 to vivado 19.1. I have migrated vhdl code easily but facing problem in migration of processor side. I have created a new block design in vivado by using IP integrater with the reference of MHS file in ISE. In ISE 8.1 block design program run from SPI FLASH which is connected to microblaze and which copy the contents from FLASH to SRAM (external memory connected to microblaze in block design). In zynq 7000 as FLASH
  5. Hey, Thanks for reply. I have found the problem in diode.Now it is working properly.
  6. Dear All, I am using MIO pins 44,45 for UART1 in ZYNQ. For that i have created block design in vivado 2019.1 by taking zynq processing system .export hardware and launch sdk. In sdk I have made a simple hello world application.I have set the baudrate and all other parameters of SDK terminal but hello world is not printing although it is working for EMIO pins. My all the uart are on 500 bank which has 1.8v and EMIO pins have 3.3v. I have checked 2 MIO pins on bank 501 which has also 3.3 v.On that it is working. Only for 1.8volt it is not working as we have used isolator
