Mathworks ipcore test using axi4stream in linux

Hello,

I'm using an ipcore generated using hdlcoder, I placed it in vivado generated the bitstream and compiled it to the BOOT.bin file.

The purpose is to test my ipcore in linux, Im using the Analogdevice_kernel, which includes the mathworks kernel driver for the ipcores.

I tried to match the device tree present in the matlab_buildroot repository.

the problem is when the board is booting it shows that the AxiDMA engine are probed, but the dma buffer cannot be created, so the device is defered.

Do I have a problem in the device tree?

fpga_axi: fpga-axi@0 {
		compatible = "simple-bus";
		interrupt-parent = <&intc>;
		#address-cells = <0x1>;
		#size-cells = <0x1>;
		ranges;
				
		axi_dma_0: axidma@40400000 {
			compatible = "xlnx,axi-dma-1.00.a";
			reg = <0x40400000 0x10000>;
			#dma-cells = <0x1>;
			xlnx,include-sg = <0x0>;
			xlnx,addrwidth = <32>;
			xlnx,axistream-connected = <0x1>;
			clock-names = "s_axi_lite_aclk", "m_axi_mm2s_aclk";
			clocks = <&clkc 15>, <&clkc 15>;
			
			dma-channel@40400000  {
				compatible = "xlnx,axi-dma-mm2s-channel";
				xlnx,datawidth = <64>;
				interrupts = <0x0 44 4>;
			};
		};

		matlab_ip: ip_core@43c00000 {

};

When the board is booting as I mentioned before the axidma are good :

xilinx-vdma 40400000.axidma: Xilinx AXI DMA Engine Driver Probed!!
xilinx-vdma 40410000.axidma: Xilinx AXI DMA Engine Driver Probed!!

but not the ipCore :
