[Compiling library on Raspberry Pi]

Just clarification: I am using 7" RPi touchscreen connected with DSI bus. I got example running by commenting out USE_SET_MODE definition and nearly all checks at board_init in board_framebuffer.h. Result is not very pleasing though... graphics are not as they should be as per attached photo

Quick reply to myself. I changed the platform specific .mk file (ugfx/tools/gmake_scripts/cpu_raspberrypi.mk) to:

# This file is subject to the terms of the GFX License. If a copy of

#SRCFLAGS += -march=armv6zk -mcpu=arm1176jzf-s -mtune=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard
#LDFLAGS  += -march=armv6zk -mcpu=arm1176jzf-s -mtune=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard
SRCFLAGS += -mcpu=cortex-a72 -mtune=cortex-a72
LDFLAGS  += -mcpu=cortex-a72 -mtune=cortex-a72

It compiles, but example does not start and complains this: GDISP Framebuffer: Failed to set video mode

I started to get test the library by going thru example from https://wiki.ugfx.io/index.php/Raspberry_Pi

but I ran into issue compiling the example: 

.
C Compiler Options....

gcc: error: unrecognized command line option ‘-mfloat-abi=hard’
make: *** [../resources/ugfx/tools/gmake_scripts/compiler_gcc.mk:254: .build/obj/GFXLIB/src/gfx.o] 

I am trying to compile this on Raspberry Pi 4 

Any quick suggestion or idea what could be wrong? Some compiler flag missing/wring, wrong compiler/linker or something else?
