1.1.
Pre-Conditions and DC/DC Check
Before power on, please check the board according to the relevant block diagram and circuit diagram, and
make sure that no serious issue or mistake can destroy the board. For example, the output of DC/DC and
LDO should not be shorted to ground.
Supply a suited voltage and power-on, then check the voltage according to the relevant block diagram,
circuit diagram and voltage specification within 5% margin.
For example, check SoC voltage (AV3V3, VCCK-1V2, etc.), DDR voltage (DDRV) , amplifier voltage
(Main_Power
), etc… Only the standby voltage is necessary if there is no software in the flash.

OAD Transport Stream Image
To manage quicker mass reflashing, a predefined OAD DVB-T channel (freq:850MHz / bandwidth:8MHz) is
embedded to SW core and only available into Factory mode. Some licensed IBL tools ('xxx2lli.exe', 'lli2dsm.exe',
dsmmerge.exe, …) from Intellbyte Inc. (
http://www.intellibyte.com/ ) might be necessary to create appropriate DVB
SSU TS. Over some predefine
settings such as repeated datablock insertion, null packets size, … (controllable in
configuration file), here below are mandatory OUI entries structure to prepare DSM-CC carousel image format:
OUI Entry MT31L MT31B MT31LB
CUST_OAD_OUI 408BF6 408BF6 408BF6
CUST_OAD_HW_MODEL 0x5881 0x5881 0x5881
CUST_OAD_HW_VERSION 0x0001 0x0001 0x0001
CUST_OAD_SW_MODEL (x) 0x 3101 0x 3102 0x 3102
