5 This is an example capture of the serial (UART) bootloader/firmware output on
6 a TrekStor eBook Reader 3.0 EBR30-a (Weltbild + Hugendubel Edition).
8 For details on the device see:

12 The firmware sends the debug output at 115200 baud, with 8n1 settings.
18 The logic analyzer used for capturing is a ChronoVu LA8 at a sample rate
21 The ChronoVu LA8 probes were connected to the EBR30-a device like this:
32 The sigrok command line used was:
34 sigrok-cli -d 0:samplerate=1mhz --samples 8388608 \
35 -p '1-8,2=TX' --wait-trigger --triggers 2=1 \
36 -o trekstor_ebr30_a_uart.sr
38 The capturing starts when the TX signal is high for the first time (it's low
39 before the device is powered-on). We capture as many samples as fit into the
40 8MByte buffer of the logic analyzer.
42 The capture does not contain the complete bootloader/firmware output.
