“Supported” means “just pass sanity check”. It does not guarantee the operation of full functionality.
(1) Audio only supports sampling rate 44.1 kHz.
(2) It’s required to build image with "export ENABLE_BT_SUPPORT=true"
(3) It’s required to build image with "export USE_USB_WIFI=true"
(4) Supported Decode/Encode H.264 (resolution from 224x96 to 1920x1080) and H.265 (resolution from 256x96 to 1920x1080).
(5) Tested USB device: Logitech C930e.
(6) The CMOS sensor (OV5645) in the MIPI camera is no longer available and should not be used for mass production. Any software support provided is for evaluation purposes only. To use MIPI Camera, please read MIPI Camera module
(7) EAS does not support platforms with symmetric CPU topologies.
(8) No support external storage on SD1 slot when booting Android image by SD card on SD2 slot.
(9) It’s required to build image with "export USE_FASTBOOTD_FOR_UDP=true". Fastboot UDP does not work on Ethernet port (CN6).

Known issues/Limitation¶
| No. | Issue |
|---|---|
| 1 | Chrome crashes because it requires 32-bit support. Currently, we do not support 32-bit on AOSP 15. So, it is marked as software limitation. WORKAROUND: Using Firefox. |
| 2 | Low performance was observed when playing back 60p streams with GPU scaling (e.g., Playing back HD stream on a Full HD display). Please check part GPU limitation |
| 3 | H.265 Decode: Temporary visual artifacts may rarely occur during fast forward/rewind operations. Normal playback resumes once the operation completes. |
| 4 | Horizontal noise/flickering when changing mode on MXPlayer when playback H264 224x96 (or some codecs random cases) due to high GPU usage. Please check part GPU limitation |
| 5 | Using Screen Record application accessed from Quick Setting to record screen can cause soft reboot on FBE (File-Based encryption) environment after hit stop button. Please check part Screen record issue from Quick Setting |
Note¶
| No. | Note |
|---|---|
| 1 | Important note: This RZ AOSP 15 only supports arm64-v8a (64-bit only) as primary architecture. No secondary architecture (armeabi-v7a) (32-bit) support. So, users can only install applications which support arm64-v8a. |
| 2 | It’s NOT recommended to hot-plug HDMI. It may cause the board broken. |
| 3 | This release is fully tested for “Base” build option. Other build options are NOT fully tested. |
| 4 | It's required to disable "Auto Select" feature on monitor to disable auto scanning input. |
| 5 | It's required to plug external power if users use external devices like portable monitor, USB hub..., etc. |
| 6 | No support external storage on SD1 slot when booting Android image by SD card on SD2 slot. |
| 7 | codec_bin partition won’t be updated during OTA update |
| 8 | Some .aac audio files might show the wrong total time. Known limitation with inaccurate duration reporting for raw AAC (ADTS) files due to Variable Bitrate (VBR) characteristics |
