Tool/software: Linux
Hello,
I also met such as following the same issue:
https://e2e.ti.com/support/arm/sitara_arm/f/791/t/596177?tisearch=e2e-sitesearch&keymatch=camera
My board information(Startup info) with SDK 4.0.0.4 version
CPU : DRA752-GP ES2.0
Model: TI AM572x EVM Rev A3
Board: AM572x EVM REV A.30
DRAM: 2 GiB
MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1
I bought TI AM57xx EVM Camera board a few mounths ago.
But now run the two sample program(qt-opencv-opencl-opengl-multithread, dualcamera) ,then we can see results as shown below on the dev kit
root@am57xx-evm:~# qt-opencv-opencl-opengl-multithreaded
Using Wayland-EGL
wlpvr: PVR Services Initialised

----------------------------------------------------------------------------
I found that sometimes(some SDK version, but I don't remember which version) detected by EVM, but do'nt sometimes(include latest version 4.0.0.4) also.
I 'm afraid there is something wrong with the device tree of the last few versions , or on other issues...
Best Regards
David.
