VK-RZV2L board running AI demo problem with udmabuf

Teodor Vendov

Hello,

We are trying to run AI demos on vk-rzv2l board and the following error appear:

root@vkrzv2l:~/tvm# ./object_detection
[ERROR] Failed to open udmabuf0/phys_addr : errno=2

How to add udmabuf ?

BR,

Teodor

    Hello Teodor,

    the udmabuf0 is added by the DRP-AI support package. Did you add that ?

    Additionally, please check the VLP release version. It's important to use the same version for the Linux package and SDK.
    My recommendation is to use the latest version (VLP 3.0.4) and the corresponding DRP-AI support package, of course.

    Kind Regards,

    Stefan
