Building HDL from Reference Files

Question

We're having trouble building the HDL from source and capturing samples using the python scripts from github. We're using the board design available here ( github.com/.../hdl) and the python drivers here ( github.com/.../pyadi-iio) to capture data. 
 
 Here our are steps for generating the build image: 
 We're pulling the repo down, following the steps here( wiki.analog.com/.../build) to build the .xsa. Then running this script to generate the BOOT.bin based on these steps ( wiki.analog.com/.../build-the-zynq-boot-image) . We're using the boot files that came with the sdcard from zynq-common. 
 
 We've tried building in both Vivado/Vitas 2021. and 2023. I can tell the capture is not correct when we are using test signals to capture. 
 
 We also verified the zedboard and FMC card are working by using the SD card that came with the board and the same python script to capture data with the SD card that came with the board. 
 
 Any thoughts on what could be wrong with our build process? Does anyone have experience using the HDL from GitHub to work with this FMC card?

Hi Chaii, 
 Sorry for the delay, but only now I notice step 3 is wrong. 
 Step 3 should be: 
 projects/ad4630_fmc/zed$ export ADI_IGNORE_VERSION_CHECK=1 projects/ad4630_fmc/zed$ make 
 Then you will find the system_top.xsa in projects/ad4630_fmc/zed/ad4630_fmc_zed.sdk 
 To build the BOOT.BIN, you first need the u-boot.elf from the u-boot-xlnx repo that you used before. 
 In u-boot-xlnx folder, do you remember that you ran make distclean -> make zynq_zed_defconfig -> make ? I showed you in my screenshot. After that, you need to run cp u-boot "./u-boot_${defcfg//_defconfig/}.elf" to add the .elf extension to the u-boot. Then you use u-boot.elf to generate the BOOT.BIN. 
 In the folder projects/ad4630_fmc/zed you need to have the u-boot.elf and the system_top.xsa . 
 Then generate the BOOT.BIN, using this script: https://wiki.analog.com/resources/tools-software/linux-software/build-the-zynq-boot-image 
 chaii said: Can you also please confirm what repo I should use to grab samples that are being sent from the zedboard? 
 After you have the BOOT.BIN, uImage and devicetree.dtb in your BOOT partition of the SD card, and you turn on Zedboard, you can connect to it an UART cable and an Ethernet cable, and through UART to find the IP of the board. Then using that IP, you can use IIO Oscilloscope application. 
 Just download it from here , open it, and do step 2 from here: https://wiki.analog.com/resources/tools-software/linux-software/iio_oscilloscope#running_remote
