# Core3566 <img src="https://www.luckfox.com/image/cache/catalog/luckfox-100px-100x100.png" style="height:7mm"/>

## Install Gentoo <img src="https://www.gentoo.org/assets/img/logo/gentoo-signet.svg" alt="Gentoo Linux" style="height:7mm;position:relative;bottom:-1mm;"/>
- Connect Core3566 to computer in maskrom mode with USB.
- Connect serial cable to GPIO header pins 8 and 10 and listen using serial terminal emulator like `picocom -b 1500000 -e p /dev/ttyUSB0`
- `Docker` with privileges is needed. Run below commands in terminal.
```bash
mkdir -p ~/workspace
cd ~/workspace
curl -LO https://raw.githubusercontent.com/Necktwi/core3566/refs/heads/master/core3566Gentoo.sh
chmod +x core3566Gentoo.sh
./core3566Gentoo.sh
```
- This should build and flash Gentoo to Core3566 to give a login prompt in `picocom`.
- Running `core3566Gentoo.sh` again, may b to install Gentoo on another Core3566 or previous run failed, it won't do redundant work like downloading and building sources, it uses already built binaries.
- To start fresh, run `./core3566Gentoo.sh clean`.

### Overlays
- To disable `HDMI` and `USB`, may b to conserve power, remove `/core3566-waveshare-cm4-io-base-b-usb.dtbo /core3566-waveshare-cm4-io-base-b-hdmi.dtbo` from `FDTOVERLAYS` in `/boot/extlinux/extlinux.conf`
- To enable `CMOS RTC` add `/core3566-waveshare-cm4-io-base-b-rtc.dtbo` to overlays and add `blacklist rtc_rk808` to `/etc/modprobe.d/blacklist-rtc-rk808.conf`
  - With CMOS battery installed, time will be persisted after 2 reboots.
- To control fan with header 4, use `/core3566-waveshare-cm4-io-base-b-fan.dtbo`

## Making SD card out of stock images
1. If SDK already installed go to 2 else download LUCKFOX_LINUX419_SDK from [here](https://drive.google.com/drive/folders/1HCNYaVqQMv0vGc4630fmHkq2Eldi9Y2z)
   as ~/Dowloads/luckfox-sdk.tar.gz
```
mkdir -p ~/workspace/luckfox && cd ~/workspace/luckfox
tar xvf ~/Downloads/luckfox-sdk.tar.gz
mkdir -p .pyvenv/bin
ln -s /usr/bin/python2 .pyvenv/bin/python
export PATH=".pyvenv/bin:$PATH"
.repo/repo/repo sync -l
```
2. Build the kernel
```
export CROSS_COMPILE="$(pwd)/prebuilts/gcc/linux-x86/aarch64/gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-"
cd kernel
make ARCH=arm64 CC="${CROSS_COMPILE}gcc" -j`nproc` luckfox_core3566_linux_defconfig
make ARCH=arm64 CC="${CROSS_COMPILE}gcc" -j`nproc` rockchip/core3566-hdmi-lp4x-v1-linux.dtb Image
```
3. Download one of the OS images from [here](https://drive.google.com/drive/folders/1ac_wZOGWZGYym02FX6t44EKQeRXdm3OW) as ~/Downloads/core3566.img
```
cd ~/workspace/luckfox/tools/linux/Linux_Pack_Firmware/rockdev/
ln -s ~/Downloads/core3566.img ./update.img
./unpack.sh #gives ./output/Image/ with rootfs image
```
4. Make sdcard with a 64MB fat32 partiton and a ext4 partition with remaining space. format them and assign labels bootfs and rootfs.
5. Mount `rootfs` on `/mnt/sd/` and `bootfs` on `/mnt/sd/boot`
6. Prepare SD card
```
sudo mkdir /mnt/img
sudo mount ~/workspace/luckfox/tools/linux/Linux_Pack_Firmware/rockdev/output/Image/rootfs.img /mnt/img
sudo mkdir /mnt/img/oem
sudo mount ~/workspace/luckfox/tools/linux/Linux_Pack_Firmware/rockdev/output/Image/oem.img /mnt/img/oem
# comment out oem and userdata in fstab
sudo rsync -avpPh /mnt/img/ /mnt/sd
sudo cp ~/workspace/luckfox/kernel/arch/arm64/boot/Image /mnt/sd/boot/
sudo cp ~/workspace/luckfox/kernel/arch/arm64/boot/dts/rockchip/core3566-hdmi-lp4x-v1-linux.dtb /mnt/sd/boot/
sudo mkdir /mnt/sd/boot/extlinux/
sudo tee /mnt/sd/boot/extlinux/extlinux.conf <<EOF
LABEL Linux
KERNEL /Image
FDT /core3566-hdmi-lp4x-v1-linux.dtb
FDTOVERLAYS /overlays/i2c5.dtbo
APPEND root=PARTLABEL=rootfs rw rootwait earlycon=uart8250,mmio32,0xfe660000 console=ttyS2,1500000 console=tty1
EOF
sudo umount -R /mnt/bpi
```
7. Insert SD card into core3566 io base and boot
8. [dmesg](files/linaro.dmesg)
9. [dts](files/linaroCore3566.dts)

## Troubleshooting
- to boot independent of `extlinux.conf` from `u-boot` console
```
mmc dev 0
fatload mmc 0:1 0x02080000 /Image
fatload mmc 0:1 0x0a100000 /rk3566-core3566.dtb
setenv bootargs "root=PARTLABEL=rootfs rw rootwait earlycon=uart8250,mmio32,0xfe660000 console=ttyS2,1500000 console=tty1"
booti 0x02080000 - 0x0a100000
```

## 52Pi New Ice Tower Cooler EP-0107
- 3pin; black: gnd, red: 12/5v, blue: pwm control
- no tach

## OV5647

### Working Configuration (from RPi3B)

The OV5647 camera module works in **MIPI CSI-2 mode** (not DVP). Key findings from RPi3B analysis:

**Sensor Properties:**
```
compatible = "ovti,ov5647"
reg = <0x36>
```

**Clock:**
```
clock-frequency = <25000000>  (25MHz, fixed-clock)
```

**CSI Endpoint (MIPI CSI-2 mode):**
```
data-lanes = <1 2>           (2 lanes)
clock-lanes = <0>            (clock on lane 0)
clock-noncontinuous
link-frequencies = /bits/ 64 <297000000>  (297MHz)
```

**Power Supplies (3 required):**
| Supply | Description | Typical Voltage |
|--------|-------------|-----------------|
| avdd-supply | Analog | 2.8V |
| dovdd-supply | Digital I/O | 1.8V |
| dvdd-supply | Digital Core | 1.2V |

**Regulator Settings:**
```
startup-delay-us = <20000>  (20ms delay after enable)
enable-active-high
```

**I2C Bus:** i2c0mux/i2c@1 (camera I2C bus via mux)
**CSI:** csi@7e801000 (unicam)

- `rpicam-jpeg -o test.jpg --nopreview` - **WORKS**
- `vcgencmd get_camera` shows detected
- I2C address 0x36 responds when driver loaded
- Raspbian ov5647 overlay: `arch/arm/boot/dts/overlays/ov5647-overlay.dts`
- Raspbian ov5647 dtsi: `arch/arm/boot/dts/overlays/ov5647.dtsi`

### Core3566 key findings
- `i2cdetect -y 1` on core shows UU at 0x36
- /mnt/ventoy/workspace/linux-v7.0-rc7-core3566-ov5647/arch/arm64/boot/dts/rockchip/core3566-waveshare-cm4-io-base-b-ov5647.dtso is cross compiled on a container on the computer named slick; `ssh slick`
