TrekStor eBook Reader 3.0 UART
-------------------------------------------------------------------------------

This is an example capture of the serial (UART) bootloader/firmware output on
a TrekStor eBook Reader 3.0 EBR30-a (Weltbild + Hugendubel Edition).

For details on the device see:

  http://randomprojects.org/wiki/TrekStor_eBook_Reader_3.0_EBR30-a_(Weltbild_%2B_Hugendubel_Edition)

The firmware sends the debug output at 115200 baud, with 8n1 settings.


Logic analyzer setup
--------------------

The logic analyzer used was a ChronoVu LA8 (at 1MHz):

  Probe       EBR30-a
  -------------------
  1 (orange)  TX


Data
----

The sigrok command line used was:

  sigrok-cli -d 0:samplerate=1mhz --samples 8388608 \
             -p '1-8,2=TX' --wait-trigger --triggers 2=1 \
             -o trekstor_ebr30_a_uart.sr

The capturing starts when the TX signal is high for the first time (it's low
before the device is powered-on). We capture as many samples as fit into the
8MByte buffer of the logic analyzer.

The capture does not contain the complete bootloader/firmware output.
