Activating Unified Bed Levelling Problem

[ChritstianAlexander]

Hi,

I have the setup working with Bilinear and the BLTouch. I tried UBL and had this message when compiling:-

c:/users/admin/.platformio/packages/[email protected]/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/bin/ld.exe: ### region `rom' overflowed by 13260 bytes
collect2.exe: error: ld returned 1 exit status

*** [.pio\build\BIGTREE_SKR_MINI\firmware.elf] Error 1

It Failed.

I changed the configuration.h file i accordance with Chris's Basement youtube tutorial on UBL https://www.youtube.com/watch?v=ONpKxkil16Q

Those settings worked fine on the MKS Gen L board.

Why would the ROM overflow? Is that a result of no EEPROM?

Any ideas on getting UBL to work?

Thanks,

Christian

these mini E3 boards only have 256k of flash, and by enabling some or a combination of the features, it won't fit. If you have TMC_DEBUG enabled, try disabling that. Yes it is also related to the EEPROM flash storage if enabled.

BTT should have really manufactured these boards with the "RE" version of the chip which would have given us 512k
