Just received this thingie. I was attracted by the price, avaliability of kernel sources and the fact I really needed an embedded PC for my needs. Once I got it, the dongle with usb and ethernet caught my attention so I disassembled it. And… what do I see?
USB power misses electrolytic caps, and… Yep, no need to open up the tablet this time. The UART is here. A bit of work and the renewed dongle is ready.
PS. I really should pop in some caps once I get to the lab…
Hi, Nice post I went via the same find…
where you able to work with the UART,
I think its 3.3V level not RS so you will need to have a converter connected, no ?
also I understand the UART is connected to the linux consol, do you know how to redirect that to an application on the tablet ?
this issue is driving me crazy any help is appreciated …
Thanks!!!
Yep, 3.3 volts. I have the TTL dongles around so I don’t use max232 or whatsoever in there.
to disable – remove console=/dev/ttyS?? or whatsoever from kernel cmdline in uboot and use it.
Hello, I manage to solder a connector, I’ve got the shell interface working but How can I use it in apps? How do you edit the uboot options? thank you!
