I think there is time for some update.

Still because all the covid situation my job tries to kill me from the exhaustion and it almost end with success

But this time I have only few boards to finish, I hope I will be able to send that darn boards back before fully functional, working Leste will be available for N900. My friend told me he will be able to obtain some memory chips compatible for that Ti CPUs which are mounted as sandwich. Soldering those at home even with stencil is a nightmare but still - I will want to make an experiment on at least one board.
