Thank you, François!
Unfortunately, dmesg seems to not remember the last time the device rebooted and shows the suspend/wake up cycle. But the mention of SDIO got me digging
.
Looking at the
Freescale i.MX508 documentation (processor in Kobo Touch) tells us that the chip provides two ports: one OTG, the other host mode. Sounds good
. The physical port on the device looks like a
micro-B, but I could not find any decent pictures. Could anyone confirm this?
Another thing I liked in the docs was the mention of 5 (!) UART ports, I wonder if there are any that one could easily (with the help of soldering iron) connect to...
