ADB SD Card logging
Upon tablet boot, if there is an SD Card found and the card has a file
named “DebugLogRecorder.ini” in the root folder, the OS will:
● If a folder named “logs” is not found in the root directory, a
folder will be created named “logs” in the root directory.
● If a folder named “logs” is present on the SD Card the OS
will:
○ A new file will be created in the “logs” directory
with the file name
“<ModelNumber>_YYYY_MM_DD_HHMMSS_kmsg.t
xt”. The “/proc/kmsg” will be written to this new
file until the tablet shutsdown.
○ A new file will be created in the “logs” directory
with the file name
“<ModelNumber>_YYYY_MM_DD_HHMMSS_logcat
.txt”. The “logcat -v time” will be written into this
file until the tablet shutsdown.
○ Each file will have the following naming rules:
■
ModelNumber = TND540
■
YYYY = system clock Year.
■
MM = system clock Month.
■
HHMMSS = Hour, Minute and second from
the system clock.
ADB log services
In Android’s “Settings
-
>Developer options” a new menu item must be
added that will be called “Log services” with two sub items:
● “Enable Log Services” with a radio button that defaults to Off
upon tablet boot.
○ Subheading “Log path: /mnt/sdcard/rmmsg”
○ When the radio button is turned on:
■
The OS will create a folder
“/mnt/sdcard/rmmsg” if it does not exist.
■
If the “/mnt/sdcard/rmmsg” folder exists, a
new file will be created in that directory
with the file name
“<ModelNumber>_YYYY_MM_DD_HHMMS
S_kmsg.txt”. The “/proc/kmsg” will be
written to this new file until the radio
button is turned Off or the tablet is
shutdown.
■
If the “/mnt/sdcard/rmmsg” folder exists, a
new file will be created in that directory
with the file name
