orange pi iot 2g notes
View orangepi.txt
General notes on OrangePi boards:
On the download page you will find many SD card images but not a single image works as one would expect.
Do not forget to set the boot switch to SDCARD instead of NAND!!!! If you are not sure what are you doing, try turning the device on
without SD card and if it is booting, it uses NAND. You will also notice this after logging in, when you are not able to create or modify
any file, since the FS is mounted as read only.
There is on board UART running at unusual 921600 bauds next to USB port (GND/RX/TX), or for OrangePi IOT 3G you need to connect to
USART2 on extension header. Use putty on windows or screen on linux/osx to talk to this device. If you receive garbage even when
the baudrate is correct, check your UART connection if it is correctly grounded or power the orangePi directly from USB port of your
computer. If you will receive shitload of debugging messages, reduce them by calling

pcb markings: MPT3050A-V5.6 2015-08-06 QJB7.820.290 698580
sold as PS2002H or Tekpower TP3016M
On the PCB there is CN2 connector with pins: TX, GND, RX. It is a uart at 115200 bauds which
generates some debugging information from STM32F100 processor.
It does not respond to common AT commands, neither to any random characters transmitted over
uart, list of some received messages follows. If you will find out what protocol this device
uses, please let us know in comments section

Someone on the forums was complaining about expired sample model jarvis.umdl:!topic/snowboy-discussion/uWrtW6W0TiM
Look at the history of jarvis.umdl, there are two revisions - new one with unlimited expiration:
Download both revisions and see what is different:
