How to implement color key with IMX7 sabre board?
Mentioned platform is lacking with IPU and graphic hardware acceleration (2D and 3D)
I was trying to do NXP test build in
example of PXP by running:
"root@imx7dsabresd:/unit_tests/Display# ./pxp_test.out -I "-h -v -l 10 -t 100"
---- Running < ./pxp_test.out > alloc_contig_range: [ac140, ac16b) PFNs busy
pxp_test.c:260 requested chan handle 0
pxp_test.c:360 opening this fb_dev - /dev/fb0
pxp_test.c:360 opening this fb_dev - /dev/fb1
pxp_test.c:360 opening this fb_dev - /dev/fb2
pxp_test.c:363 Unable to open /dev/fb2
---- Test < ./pxp_test.out > ended ----"
it is failing and it is expecting "mxc_epdc_fb" if frame buffer id is different then I would failed,
Unfortunately I don't have EPDC interface connected,
I was able to modified /imx-test-5.9/test/pxp_lib_test/pxp_test.c file but it faild in two places:
ret = ioctl(fd_fb, FBIOPUT_VSCREENINFO, &var); // this could be omitted
retval = ioctl(fd_fb, MXCFB_SEND_UPDATE, &upd_data); // always failed
Any advice how to implement color keying with IMX7D sabre board ?
