Hi Ti experts,
we met a gpu error during linux kernel booting on our own ECU:
...
[ 4.142680] pvrsrvkm 4e20000000.gpu: adding gpu_0 device link failed!
...
the rootfs we use is based on the tiny-fs from linux sdk(tisdk-tiny-image-j721s2-evm.tar.xz) and have some modification according to our APP , the gpu on the device tree is:
gpu: gpu@4e20000000 {
compatible = "ti,j721s2-pvr", "img,pvr-bxs64";
reg = <0x4e 0x20000000 0x00 0x80000>;
interrupts = <GIC_SPI 24 IRQ_TYPE_LEVEL_HIGH>;
power-domains = <&k3_pds 130 TI_SCI_PD_EXCLUSIVE>,
<&k3_pds 373 TI_SCI_PD_EXCLUSIVE>;
power-domain-names = "gpu_0", "gpucore_0";
clocks = <&k3_clks 130 1>;
};
the sdk version is ti-processor-sdk-linux-j721s2-evm-08_05_00_08.
could you help analyze why this error got reported?
