Error of no DPU core found in current configuration of DPU IP!

Hi,

I am following the DPU integration tutorial. I am getting this error when I boot on ZU4EV board. Although, I have checked for the previous answers on the Xilinx forum none of solutions did apply on solving this error. The error presented is shown below.

[    4.121067] [DPU][2102]Found DPU signature addr = 0xbf000000 in device-tree
[    4.128023] [DPU][2102]Checking DPU signature at addr = 0xbff00000,
[    4.134387] [DPU][2102]DPU signature NOT found, fallback to device-tree.
[    4.141082] [DPU][2102]Error of no DPU core found in current configuration of DPU IP!

In addition, when the DPU signature and signature VA is checked by prinintg the fields in dpucore.c file (line 1139)

if (signature_addr != SIG_BASE_NULL) {
dpr_init("Checking DPU signature at addr = 0x%lx, \n", signature_addr);
signature_va =
ioremap((phys_addr_t)signature_addr, 1 * sizeof(signature_field));
signature_field = ioread32(signature_va);

dpr_init("Checking DPU signature field is = 0x%lx, \n",signature_field);
dpr_init("Checking DPU signature VA field is = 0x%lx, \n",signature_va);

 

I get the following error on booting:

I attaching the system-user.dtsi.

The PL interface is PL_PS_IRQ1 the GIC RIQ number is 143:136. The interrupt number calculated is (136-32=104) which is 68 hex.

Can you please help me resolve this!

Thank you
