[never mind, i was being dense.] something is pretty wrong if a grid is showing up as an arc, showing up as multiple tty devices, &c. i would try 1) different USB ports, 2) mounting the norns in disk mode and running fsck on it, 3) re-flashing the disk image, &c.
might be a good time to take the discussion offline, since i donât think this is directly related to the contents of the 2.0 update⊠or maybe need a general FAQ regarding steps to take in case of apparent hardware failure or filesystem corruption.
for completeness: youâre not running some crazy script that allocates all the memory in the system⊠are you?
[mod hat: iâm considering moving all of this to the Help thread.]
