Marlin 2.1 dev.x Pour Markerbase Gen L

I did not modify the original file provided with the Tevo Tornado config, just LPC1768, which I replaced.
I modified as you said in platformio.ini

Message:

I don’t know if the platformio updates as arduino does automatically. I am not used to using platformio.
In addition I have 2 cards that I update with Marlin 2.0 the other is Bigtree_SKR_Pro_1.1 and I have problems with the Built.
