Hi, it looks like the ra8875 driver is included, at least for the kernel I'm running:
debian@beaglebone:~$ modinfo /lib/modules/4.16.0-rc2-bone3/kernel/drivers/staging/fbtft/fb_ra8875.ko.xz filename: /lib/modules/4.16.0-rc2-bone3/kernel/drivers/staging/fbtft/fb_ra8875.ko.xz license: GPL author: Pf@nne description: FB driver for the RA8875 LCD Controller alias: platform:ra8875 alias: spi:ra8875 alias: platform:fb_ra8875 alias: spi:fb_ra8875 alias: of:N*T*Craio,ra8875C* alias: of:N*T*Craio,ra8875 depends: fbtft staging: Y intree: Y name: fb_ra8875 vermagic: 4.16.0-rc2-bone3 mod_unload modversions ARMv7 p2v8 fyi - I installed that kernel with this command: sudo /opt/scripts/tools/update_kernel.sh --bone-channel --exp This page from the fbtft wiki might be of interest: https://github.com/notro/fbtft/wiki/fbtft_device#parameters Here is example of the parameters one person uses: https://github.com/notro/fbtft/issues/476 I'm curious which RA8875 display do you have? I do support for Adafruit so I could request this one to try it out: https://www.adafruit.com/product/1590 thanks, drew On Wed, Feb 21, 2018 at 9:48 PM, evilwulfie <[email protected]> wrote: > How would one know if if a particular driver is already build in the bone > kernel fb_ra8875.c > > > https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/tree/drivers/staging/fbtft?h=staging-testing > > root@bone:/home/debian# modinfo fbtft > filename: > /lib/modules/4.9.78-ti-r94/kernel/drivers/staging/fbtft/fbtft.ko > license: GPL > depends: > staging: Y > intree: Y > vermagic: 4.9.78-ti-r94 SMP preempt mod_unload modversions ARMv7 p2v8 > parm: debug:override device debug level (ulong) > > > If the driver is already compiled in how would one add it to a device tree > file for use > > spi driven device but no dc pin, first command byte upper bits select either > a command or data and w/r > > kinda a different animal than most tft displays > > -- > For more options, visit http://beagleboard.org/discuss > --- > You received this message because you are subscribed to the Google Groups > "BeagleBoard" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion on the web visit > https://groups.google.com/d/msgid/beagleboard/7eb65c10-babd-33d3-b1d9-304b0b757fb1%40gmail.com. > For more options, visit https://groups.google.com/d/optout. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
