Frame Buffer size on Resesas RZ A1H kit is 32 bit. I'm trying to change the frame buffer size to 16 bit.
cat /sys/devices/platform/vdc5fb.0/graphics/fb0/bits_per_pixel command on RZ A1H kit returns 32.
Tried changing the frame buffer size on desktop,
I have tried to change the grub configuration in /etc/default/grub file, enabled below macros
#GRUB_GFXMODE=640x480x16
#GRUB_GFXPLAYLOAD_LINUX=keep
Below is the command to update the above made changes
psm_vm@psmvm:/etc/default$ sudo grub-mkconfig -o /boot/grub/grub.cfg
Generating grub configuration file ...
Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.

But, none of the above changes had any impact on FrameBuffer size.
Please let me know how can I change the fb size to 16 bit. ( both on Rz A1H kit and Ubuntu Linux Desktop)
