Hi Kernel Please ignore my last mail, no need to test v6, should have the same issue. I found the cause in Kconfig. 495 config VIDEO_STM32_DMA2D 496 tristate "STM32 Chrom-Art Accelerator (DMA2D)" 497 depends on (VIDEO_DEV && VIDEO_V4L2 && ARCH_STM32) || COMPILE_TEST should be 497 depends on VIDEO_DEV && VIDEO_V4L2 && (ARCH_STM32 || COMPILE_TEST) Will send v7 right now. Hi Hans, Mauro Sorry for trouble, I need to send a patch to fix the compile test issue. Could you help to drop the v6 version, thanks.
