Hello! I am trying to get u boot running on the samsung-espresso3g (https://wiki.postmarketos.org/wiki/Samsung_Galaxy_Tab_2_7.0%22_(samsung-espresso3g)) but it gets stuck at the bootsplash (ie the Samsung logo). Here is my fork https://github.com/MightyM17/u-boot/tree/espresso-dev. Any guidance on what i should do?
