trying to edit and upload firmware, Y axis backward?

[mrupndown]

I downloaded the firmware from the Geeetech website. I edited it according to the manual configuration H Define invert y axis to false, but when I try to upload it, an error code comes up that has nothing to do with the Axis's.

uint8_t u8g_dev_rrd_st7920_128x64_fn(u8g_t *u8g, u8g_dev_t *dev, uint8_t msg, void *arg)

Not sure what this is even referring to so have no idea how to fix it, and it won't up load until its fixed it doesn't look like? It appears to be ultra LED or LCD. how do I make this argument happy? I am working with a New prusa I3 A PRO, and the Y axis is moving the wrong direction, away from the limit switch when homing.

Have you tried using repetier host settings to change the y direction? I found that easier than the firmware

Did you solve this?
I have the same problem
Their firmware is just SH*TE
