SPI path not set. LMK not found on device tree. Issue with BSP of RFSoC4x2

Hey All,

I am trying to rebuild PetaLinux from the BSP file with small modification to the CMA. However with no success.

To reconstruct my error without changing the bootargs kernel( no cma),

  1. I sourced the installed directory on PetaLinux 2022.1
  2. Run “petalinux-create -t project -s ” where is the path to the appropriate BSP file in “bsp_releases”.
  3. “petalinux-config --silentconfig”
  4. “petalinux-build”
  5. “petalinux-package --boot --u-boot --fpga images/linux/system.bit”
  6. Copied the BOOT.bin image.ub boot.scr to the root partition of my sdcard.
  7. I am using the original Rootfs of the the Image from this website.

@JennySmith888 I have seen you used the BOOT.BIN file with some changes to the dtsi file. how did you manage to avoid the error of

I used the BSP files from RealDigital and used as well the instructions in the README file.

I appreciate any ideas on how to proceed on that topic.

Thanks!

@cathalmccabe Hey Cathal, I do not know if this is related to your area of expertise. is this issue known to you guys, that the BSP is faulty?

Thanks!

@njachimi Hey Nathan, I’ve seen you published the post about the support for RFSoC4x2.
Do you know of problems with rebuilding the rootfs and boot files from bsp file?

Thanks a lot,
Ido

try adding the below config in the system-user.dtsi

&spi0 {
            status = "okay";
     
            lmk@0 {
                    compatible = "ti,lmk04828";
                    reg = <0x00>;
                    spi-max-frequency = <0x7a120>;
                    num_bytes = <0x03>;
            };
     
            lmxdac@1 {
                    compatible = "ti,lmx2594";
                    reg = <0x01>;
                    spi-max-frequency = <0x7a120>;
                    num_bytes = <0x03>;
            };
     
            lmxadc@2 {
                    compatible = "ti,lmx2594";
                    reg = <0x02>;
                    spi-max-frequency = <0x7a120>;
                    num_bytes = <0x03>;
            };
    };
