Project is not dead but I currently have no satisfying solution concerning the file system. Also, with COVID-19, I am confined at home and take that time doing some work on my house.

I have also considered replacing the flash inside the terminal with an SD card reader. It has some advantage the card handle the problem of allocating the blocks and the wear leveling, The SD card can also be extracted from the terminal and the files read or edited on any computer.

Apart from that, I have noticed that the standby mode is really efficient. My terminal is in stanby for months now (I think since mid of february) on a pack of NiMh batteries and I power it on from time to  time to look at the battery level. The batteries are slowly draining out but the terminal is still functionnal.
