[BUG] Cannot enable BL Touch without rom overflow #189

Open BorisBrock opened 4 years ago

BorisBrock commented 4 years ago

I have downloaded the latest Marlin 2.0.4.3, and patched in the BigTreeTech config*.h files. Then I enabled BL_TOUCH in the configuration.

The build then fails with the following error message:

region `rom' overflowed by 588 bytes

Is there any way to get this working? Do I need to disable other features (which ones won't hurt that much?)? Why has the board so little memory?

brew99 commented 4 years ago

set the default environment in the platformio.ini file to "STM32F103RC_bigtree_512K_USB". That should open up the RC chip to 512K, and give lots of room for extras

Also, BTT's config files are old, I'd suggest using the example configs from vanilla Marlin repo

Guide for the board.

I think this can be closed.
