Here are the steps I did to work around this issue: 1) Changed petalinux auto-generated makefile to include these lines: INC_XILT = $(shell find ../../../work/zynq_generic-xilinx-linux-gnueabi/fsbl-firmware/*/git/fsbl-firmware/fsbl-firmware/zynq_fsbl_bsp/ps7_cortexa9_0/include -prune) INC_STDI = $(shell find ../../../work/zynq_generic-xilinx-linux-gnueabi/u-boot-xlnx/*/git/include -prune) MY_CFLAGS += -g -DDEBUG -Wall -I$(INC_STDI) -I$(INC_XILT) 2) Added this bit to blink.h file: #include <xil_types.h> #ifndef char8 typedef char char8; #endif #include <xstatus.h> Assuming that your original blink.c is petalinux auto-generated file with the #include "blink.h" line from vivado auto-generated file. Explanation: 1) INC_XILT = $(...) and INC_STDI = $(...) are two paths to xil_types.h and stdio.h (a file required by xil_types.h). These paths are sent to compiler via -I flag for the compiler to search for these files. These paths are also made through $(shell find ... -prune) as one of the folders marked with * is an auto-generated folder that will change based on petalinux tool version. 2) #ifndef char8 typedef char char8; #endif For some reason char8 is conditionally defined in xil_types.h file, and the condition is false (otherwise you get even more errors), hence this piece of code tries to define char8 again. It is done with #ifndef to make sure that it is somewhat compatible with other releases of petalinux. I haven't tested what would happen if the <proj folder>/build/tmp/work/zynq_generic-xilinx-linux-gnueabi/fsbl-firmware or u-boot-xlnx have multiple folders, returning multiple variables to the "shell find" command, but I assume whoever comes looking for this answer will have only one. P.S. Outlined steps seem like a workaround rather than an actual solution.

Hello, I am having problems trying to compile custom module exported from Vivado to petalinux on Zybo z7-10. All tools are from 2022.1 build. Steps I have performed so far: 1) Used Vivado to generate a custom IP and added it to the block design as per UG1165 Chapter 7. 2) Exported blink.h, blink.c, design.xsa and system.bit files from Vivado. 1) Made and SD card with 2 partitions as described in UG1144. 2) Created a template project with --get-hw-description. 3) Added template module via petalinux-create -t modules --name blink --enable 4) Changed project-spec/meta-user/recipes-modules/blink/blink.bb to include blink.h 5) Copied blink.h from vivado to /files/ and changed blink.c (autogenerated) by adding #include "blink.h" 6) Tried to modify makefile to compile but failed as when I do petalinux-build I either get : missing xil_types.h error during compilation OR it compiles with warning "modules.symvers not found" but the module doesn't show with "modprobe blink" when connected via terminal (nor shows in unpacked rootfs) Note: when I compile a template project with a template module, and upload it onto the SDcard, then my board responds to "modprobe blink", however I would like to be able to use PL from vivado as a driver in linux. I want to do a simple project where I can use linux driver to blink PL connected LEDs, please help.
