Getting Detailed Logs on Android STB (UART+ADB)

The following guide will help you to get the most detailed logs from the Smartlabs Android STBs.

1. Install firmware with additional debug logging.
   • Contact the SmartLabs Support Team to obtain the firmware for your STB.
   • Write the firmware file on the USB flash drive.
   • Connect to the STB with ADB (see also “ADB installation instructions“) and restart in the “recovery” mode:
     adb reboot recovery
   • As soon the STB restarts, press and hold the Home and Volume- buttons on the remote until the recovery menu appears.
   • Select the Update from USB option, select the firmware file and proceed to install it.
   • On success installation, the following string should appear:
     Install from usb disk complete with result code 0.
     Install complete
   • Return to the recovery menu and do the factory reset. This may not be necessary, but is recommended.
   • Reboot the STB. The application should start as usual.

2. Connect the UART debug cable (see “UART Connection Without Soldering“) and start the terminal application.
3. If the STB over UART works properly, start saving the log and power cycle the STB in order to get full logs.
   • Please verify the firmware version:
     getprop | grep build
     and turn on debug options:

su root

cat /proc/msp/omxvdec

echo set_print 0x3 > /proc/msp/omxvdec

cat /proc/msp/omxvdec

cat /proc/vfmw/info
echo 0 0x800003 > /proc/vfmw/info
cat /proc/vfmw/info

4. Keep getting logs over UART and start getting log with ADB logcat (see “Getting Android STB logs with ADB tool“)
   • Reproduce the problem and save all logs.
