PROCESSOR-SDK-AM437X: PVR:(Error): glReadPixels: Failed to get strided data

Environment：

processor :AM4378

SDK:07.03.00.005

pvr: ti-img-sgx/1.17.4948957

display format: EGLFS

I am in the implementation of the screen capture function, using the relevant API(glReadPixels) to obtain video memory data,

But an error is returned: Failed to get strided data.

I want to know the reason for the error, is the PVR driver not supported? Or am I using it the wrong way?

I saw a similar post a few years ago, but no one ever responded.
