Run openamp echo test program fail in vek280

[yybingyybing]

Hello,
We use the example dtsi for echo test，when run the echo_linux_test in vek 280, get fail message as follow:
root@xilinx-vek280-20251:~# ./echo_linux_test
CLIENT> ****** libmetal demo: shared memory ******
metal: error: metal_uio_dev_open:169 device platform:3ed80000.shm not found
metal: error: metal_uio_dev_open:169 device platform:3ed80000.shm not found
CLIENT> ERROR: Failed to open device 3ed80000.shm.
CLIENT> ERROR: shared memory demo failed

We try two dtsi config as follow, get the same error.
1:
amba {
vring: vring@0 {
compatible = "generic-uio";
reg = <0x0 0x3ed40000 0x0 0x4000>;
};
shm0: shm@0 {
compatible = "generic-uio";
reg = <0x0 0x3ed48000 0x0 0x0100000>;
};
ipi0: ipi@0 {
compatible = "generic-uio";
reg = <0x0 0xff360000 0x0 0x20>;
interrupt-parent = <&gic>;
interrupts = <0 33 4>;
};
};
2:
amba {
vring: vring@0 {
compatible = "vring_uio";
reg = <0x0 0x3ed40000 0x0 0x40000>;
};
shm0: shm@0 {
compatible = "shm_uio";
reg = <0x0 0x3ed20000 0x0 0x0100000>;
};
ipi0: ipi@0 {
compatible = "ipi_uio";
reg = <0x0 0xff340000 0x0 0x1000>;
interrupt-parent = <&gic>;
interrupts = <0 29 4>;
};
};

Could any one give our any suggestion ?
Thanks

This was discussed here before for zynqmp platform here:

#63

Thanks @tnmysh ,

I watch #63 , but I think these is some difference between our problems.
We used petalinux 2025.1,It looks like no matter what dtsi configuration we use, we can't get/dev/uiox. So we can't use the node 3ed80000.shm. It seems there some error in petalinux 2025.1 , but I have no idea to fix it. .....
We added the openamp in petalinux, but cant get the openamp.dtb after petalinux-build ....
