Flas / Ram requirements for Marlin 2.0
March 31, 2021 12:01PM
Hello i have an simple questions as in other forum question an argument exist that the r73 Borad with STM32F103vet6 MCU has to less Ram to make a Marlin 2.0 port.

So could anyone share his knowledge if Marlin 2.0 could be ported and which restrictions exist if tey exist?

Best regards,
Frank

The VET6 has more flash and the same amount of RAM as the RCT6 which is already supported by Marlin 2.0, so there should be no reason it couldn't be ported to that chip.

Marlin 2 already supports these boards with that same MPU, without issues

#define BOARD_GTM32_PRO_VB 4005 // STM32F103VET6 controller
