unable to modprobe fb_ili9488

[DansDesigns]

Hi, I am trying to get a 3.5" ili9488 screen working with my PocketBeagle, I have had success getting a 1.8" ST7735 working and displaying the cli from the framebuffer however I am encountering the following issue when trying to install the driver for the ili9488...

I may have missed some steps..
I cloned the git into my home directory and have cd into it..
i ran sudo modprobe fbtft_device name=fb_ili9488 busnum=0
but was given:
modprobe: ERROR: could not insert 'fbtft_device': Invalid argument

as a lot of the instructions are for RasPi I am a little lost with how to install the actual ili9488.c driver..
any help would be greatly appreciated!

i think all i need is to figure out how to add the ili9488.c to my current kernel without all the hassle of rebuilding the kernel etc...

I managed to make some progress,
using sudo modprobe fbtft_device custom name=ili9488 busnum=0 rotate=0 gpios=reset:57,dc:58 cs=5 I am able to configure the GPIO pins correctly but now im getting this error:
