STM32MP157 using qt5 issue
I used buildroot to build the root file system and encountered the following error while running the qt example:
penat(AT_FDCWD, "/dev/galcore", O_RDWR) = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "/dev/graphics/galcore", O_RDWR) = -1 ENOENT (No such file or directory) clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=1, tv_nsec=0}, 0xbe8ec8d0) = 0
write(2, "[ 1] Failed to open device: "..., 72) = 72
I loaded galcore.ko, but there are indeed no galcore and graphics/galcore under/dev/:
# dmesg | grep galcore
[ 9.490473] galcore: loading out-of-tree module taints kernel.
# ls /dev/galcore*
ls: /dev/galcore*: No such file or directory
I used tslib to test touch and modetest to test LCD, both of which were normal. Why does my Qt still not run properly?
