I did the whole partition thing on the sdcard from the VM provided to us, i checked several times that i did things properly, when i try to boot the board, i get this error (https://i.gyazo.com/8de1917e123d7614949d54eb1b4539d0.png) message which is very close to the one in the pdf given, but when i interrupt the auto boot and reset the environment it keeps doing the same error after.
I don't know what i could try to fix this
