[AmebaPro2] Introduction for AmebaPro2 Flow

AmebaPro2 architecture for sensor flow

AmebaPro2 support 2 way for sensor bringing up flow

• Fast camera start flow support to get 1^st video frame as soon as possible

• Normal camera flow is used as usually for general usage.

Sensor Configuration on AmebaPro2

AmebaPro2 uses a set concept for sensor & IQ control

Note

Normal camera driver & IQ is voe based

• Version should be alignment.

Sensor configuration file in AmebaPro2 is listed as below

• project\realtek_amebapro2_v0_example\GCC-RELEASE\mp\amebapro2_sensor_set.json

  • Configuration for each driver set

• project\realtek_amebapro2_v0_example\GCC-RELEASE\mp\amebapro2_isp_iq.json

  • User can define which set index for FCS flow

• project\realtek_amebapro2_v0_example\inc\sensor.h

  • Configuration for sensor control

• amebapro2_sensor_set.json

  • User can define how many driver set

    • It support at most 9 set with 1 dummy set

    • Dummy set (set 0) can’t be removed

• sensor.h

  • Configuration for sensor control

  • User can choose which index for driver set

• amebapro2_isp_iq.json

  • User could config FCS index (in necessary)

Path for driver related bin

• component\soc\8735b\fwlib\rtl8735b\lib\source\ram\video\voe_bin

Build Code flow

• When user need to update file, it need to be put it in voe_bin

• Batch file would automatic copy file to link folder (during make stage)

  • project\realtek_amebapro2_v0_example\GCC-RELEASE\build\application

Version check

• When load sensor & iq, we would show date & timestamp for each bin

Version check

• When load sensor & iq, we would show date & timestamp for each bin

• Based on voe version in SDK, choose corresponding voe code base

Driver Code base

Code base for normal driver

• voe1470

Code base for FCS driver

• rtl8735_driver_code_fcs

IQ Bin

• Please refer to IQ tuning guide

[Normal Driver] flow for adding sensor

Prepare for sensor driver bin

• Based on VOE code base (version alignment)

Add a new sensor driver (if necessary)

• Refer to 「AmebaPro2_DriverGuide_IntroductionForPortingSensorDriver.pdf」

• Output sensor driver bin

• Copy sensor driver bin to sdk folder

• Add new folder for new sensor driver

  • Take sc2333 for example

  • Copy from same vendor sensor or same segment sensor

  • Folder Path: sensor\smartsens\sc2333\

  • File Path: sensor\smartsens\sc2333\sensor_sc2336_mipi.c

  • Open sensor driver, and replace the sensor name (sc2336 -> sc2333)

• Modify configuration for VOE code base

  • Check for new page for detail

    • \sensor\Makefile

• Compile and check output bin

  • Output folder: output\sc2333.bin

• Modify configuration for VOE code base

  • \sensor\Makefile

    1. Add folder path

    2. Add sensor driver file name

    3. Add sensor to build

[FCS Driver] flow for adding sensor

Driver Code

• Use following command to output FCS driver

• gcc -o fcs_g.exe gen_fcs_data.c

• ./fcs_g.exe

• Get fcs driver bin
