Hi, looks like this bug is the inofficial "let's get debian working on Teres-I" thread. So let me point here to https://wiki.debian.org/InstallingDebianOn/Olimex/Teres-I and invite you to contribute to that page if you have additional experiences.
I think at this time we have everything necessary in debian except for some u-boot patches to get simplefb up. TIA, Harald
