Problem with firmaware Geeetech Rostock mini G2 & G2s pro

[Rush68]

Hello everyone, my problem is the following change of computer and when verifying the firmware gives me error and tells me this
#if ENABLED (M100_FREE_MEMORY_WATCHER)
extern char * __brkval;
extern size_t __heap_start, __heap_end, __flp;
extern char __bss_end;

and the screen gives me squares.
I am using Arduino 1.8.10

What can i do

Hi,From the description of your description, it should be caused by the failure of the firmware brush.
You can get it from here:http://www.geeetech.com/forum/viewtopic ... 20&t=17046
Select your corresponding firmware to download and update.
Arduino can use some of the previous versions.

I already tested with all firmware for delta g2 & G2s and now I get this error attached screenshot.

Hi, I just did a related search. If you don't want to use the old version of Arduino, you may need to
:replace All Replace all fpos_t with f_pos_t
Note that when you replace Replace All, select "Search all Sketch Tabs"

I hope this can help you.
