3. Update List

3.1. Yocto(SUMO) BSP

3.1.1. BL1 for s5p4418

No Build Name Description Remark
1

convergence-daudio

Add the convergence-daudio board
2 con_svma Change the PLL for Audio/Memory
– Changed PLL3 vlaue for Audio DFS : 800 –> 614
– Changed clock source for memory : PLL3 –> PLL0

 

3.1.2. BL1 for s5p6818

No Build Name Description Remark
1 All When boot mode is sdmmc, boot device can be emmc onboard or external sd card, but build target was fixed to emmc.
Sometimes client needs to build bl1 with boot device sd card.
So, this patch adds following config.mk variable.
– BOOT_DEVICE : default is emmc, if want to change external sd card, change to sd.Output binary is named following BOOT_DEVICE.
– emmc -> bl1-emmcboot.bin
– sd -> bl1-sdboot.bin

 

3.1.3. u-boot

No Build Name Description Remark
1 navi_ref i) Change fb address
Logo clear issue when fastboot downloads
Changes fb address 0x50000000 to 0x7a000000
ii) Sets env values correctly.
2 daudio_ref Sets env values correctly.
3 convergence_daudio Add convergence-daudio board
4 common nxrecovery: Introduce nxrecovery command
nxrecovery is tool for fusing boot device by other bootable device.Usage scenario>
Step 1) Make bootable sdcard that has recovery image for emmc
Step 2) Boot by external sdcard and auto run nxrecovery
Step 3) nxrecovery fuses recovery image to emmcCommand>
nxrecovery <src_inf> <src_dev> <target_inf> <target_dev>
ex) recovery emmc by external sd card
$ nxrecovery mmc 1 mmc 0
5 All Implement auto recovery

This patch add function to check nexell autorecovery and when autorecovery_cmd variable is set, run command.

This is for production by external SD card.

[NOTE]
This patch has implementation of mmc_get_env_dev() function.
If you want to override this function, you must implement int nexell_mmc_get_env_dev() function.
Currently nexell_mmc_get_env_dev() function set mmc env device by reading boot mode.

3.2. Android 7.x(Nougat) BSP

3.2.1. Android

No Build Name/Feature Description Remark
1 avn_ref i) Add supporting autorecovery env
This patch adds supporting build u-boot env param for sd auto recovery image.
When sd auto recovery runs, u-boot needs to know that this boot is for autorecovery
so, autorecovery_cmd env is added and build script changes autorecovery_cmd env by ${AUTORECOVERY_CMD}.ii) build/s5p6818: Add build bl1 for external sdcard
This patch adds supporting build bl1-s5p6818 for external sdcard.
Afterwards, build for bl1 always make two binary.
– bl1-emmcboot.bin -> bootloader
– bl1-sdboot.bin -> bootloader-sdYou can make bootable sdcard by below command.
$ sudo dd if=bootloader-sd of=/dev/sd{X} ibs=512 obs=512 seek=1iii) Add yaml describing sd recovery image
This patch adds sample yaml file that is used as input file for nx-make-recovery.py.
nx-make-recovery.py tool depends on this yaml file when making sd bootable recovery image.simple description of yaml
==========================
image_dir: result directory that is made by build script
bootloader: bootloader for sd booting(made to named bootloader-sd)
make_partition: do format?
images: image description compatible with partmap.txt
– type: 1: raw, 2: raw partition, 3: ext4 sparse image
– file: file name
– dest_offset: offset at emmciv) add a new video device “video7” as a front camera compatible with a interlaced tw9992 sensor.v) Change Camera Features Name to use deinterlacer
This patch modifies a feature ‘BOARD_CAMERA_BACK_INTERLACED’ and ‘BOARD_CAMERA_FRONT_INTERLACED’ to use deinterlacer for supporting interlaced camera.
and adds a new feature ‘BOARD_CAMERA_BACK_COPY_MODE’ and ‘BOARD_CAMERA_FRONT_COPY_MODE’ to run clipper only by copying frame data for recording.vi) media: add a resolution info for new camera device
vii) media: Add a resolution for tw9992 using deinterlacerviii) sepolicy: Add nx-deinterlacer file contexts

viiii) ueventd: add /dev/nx-deinterlacer uevent rule.

 2  navi_ref i) media: add a new camera(ID:1) using tw9992 sensor

ii) config: camera: add a new Camera and modifies definitions following by CameraHAL changes.

iii) Revert “config: Disable bluetooth feature”
Since the BT function is basically provided, it must be activated regardless of whether the BT module exists or not.

 3  con_svma i) config: add a new video device device “video8” as a front camera compatible with a interlaced tw9900 sensor.

ii) media: add a resolution info for new camera device (cameraId = 1)

iii) component/quickboot: Use Home only
This patch removes following packages.
– Launcher3
– Settings
– Gallery2
– Camera2
– BluetoothMidiService
– ContactsProvider

And, add Home package that is simple home launcher.
Currently quickboot patch is extreme so general apps are not working properly.
In this mode, client apps will be added and tested.

iv) build: Fix setup_toolchain function because device/nexell/tools/common.sh is fixed for same issue.

 4  camera hal i) Fix a low framerate issue
This patch fixes a buffer queueing scenario because of a low fps issue.
One queueing by one dequeueing casue buffer underrun issues.
So it queue all registered buffer to vip when a buffer is dequeued.
And recover MAX_BUFFER_COUNT from 3 to 4 by no memory lacking issue during recording test with deinterlacing.ii) Add checking android version to integrate with exisiting code.
This patch adds checking android version to integrate with exisiting code and removes build warnings.iii) fixes a getAvaliableResolution function to support upscaling.iv) Add deinterlacing for interlaced cameraThis patch adds deinterlacer to support interlaced camera.
This feature enabled when following feature is enabled in BoardConfigCommon.mk
:BOARD_CAMERA_BACK_INTERLACED or BOARD_CAMERA_FRONT_INTERLACED for deinterlacing,
MAX_BUFFER_COUNT musb be bigger than 1 and smaller than 4
 5  nx-video-api i) Remove the header from the input stream

ii) adds used byte and remain byte in decoder.

 6 nx-deinterlacer  add nx-deinterlacer library
