New page

Some people have reported about a bootloop preventing the TV from starting through. The issue here often is, that the script invoked from within '''/mtd_exe/rc.local''' is getting stuck and preventing the exeDSP to start.
 There are two key steps that should be considered when hacking your image, to avoid such situations or at least to open a "backdoor" that allows to prevent the respective script from starting.
 
#Ensure that you send your scripts into the background when starting, by padding with a '''"&"'''. Your changes in /mtd_exe/rc.local should look like export MAPLE_DEFAULT_PATH=/mtd_cmmlib/InfoLink/lib export MAPLE_MANAGER_WIDGET_PATH=/mtd_down/widgets/manager export MAPLE_NORMAL_WIDGET_PATH=/mtd_down/widgets/normal export MAPLE_WIDGET_DATA_PATH=/mtd_down export MAPLE_WIDGET_INCLUDE_PATH=/mtd_down/widgets/inc export MAPLE_PLUGIN_DATA_PATH=/mtd_cmmlib/InfoLink/lib export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mtd_cmmlib/YWidget_LIB export KF_SLEEP_READ=-2 echo 30000 > /mtd_rwarea/DelayValue.txt #touch /mtd_rwarea/DoPrintYahoo.txt export KF_NO_INTERACTIVE=1 export KF_LOG=/dev/null''';/mtd_rwarea/rc.local&''' cd /mtd_exe/ ./exeDSP
#Include a check in your '''/mtd_rwarea/rc.local''' script, so that it will source and run a different set of commands, dependent on whether a specific file is detected on the USB-Drive or not. An example could look like: #!/bin/sh sleep 20 # Allow USB-stick to settle USB="/dtv/usb/sda1" # Your USB mount-point if [ -f $USB/usb.sh ];then . $USB/usb.sh # USB-File detected. Source and run this instead else . /mtd_rwarea/mtd_rwarea.sh # Source and run "normal startup script" fi exit
