additionally) -
Uncomment to set the WiFi parameters. Set
WIFI_SSID="Your SSID" WIFI_PASSWD="Your Password"

The feature of BIGTREETECH Pad7. All of these functions require the corresponding
BTT_PAD7="OFF" TOUCH_VIBRATION="OFF" TOUCH_SOUND="OFF" AUTO_BRIGHTNESS="OFF"
overlay
to be enabled inarmbianEnv.txt
BTT_PAD7
is the master switch of the following functions. When it is set tooff
, all the following configurations will be ignored.
TOUCH_VIBRATION
is vibration feedback when clicking on KlipperScreen buttons (Requires a special KlipperScreen version to be used together). overlaypad7_vibration

.
TOUCH_SOUND
is sound feedback when clicking on KlipperScreen buttons (Requires a special KlipperScreen version to be used together, The HDMI audio does not output the first 1-2 seconds, so this function is currently unavailable in V3.0.0). No additional overlay required
AUTO_BRIGHTNESS
is to automatically set the screen backlight brightness according to the ambient light intensity detected by the photosensitive components. overlaylight

The default value is

, This means that theUART0
of CB1 is used as the debugging port by default. We can useMobaXterm
to connect to CB1 by UART0 and debug. If klipper wants to useUART0
to control the motherboard, we need to set it toconsole=serial

CB1 will automatically identify the HDMI resolution, but if your HDMI screen cannot report the resolution through the EDID normally, we can forcibly specify the resolution of CB1 output by uncomment
extraargs=video=HDMI-A-1:1024x600-24@60
extraargs=video
and set the actual resolution.
For example:
BIGTREETECH-HDMI7 resolution = 1024x600:extraargs=video=HDMI-A-1:1024x600-24@60
BIGTREETECH-HDMI5 resolution = 800x480:extraargs=video=HDMI-A-1:800x480-24@60

Download the utility sunxi-fel to your computer (Mac OS is not supported) and download the CB1 driver For windows download sunxi-fel.exe For linux download sunxi-fel-aarch64 For arm download sunxi-fel-armhf
-
Push the DIP switch (USB OTG) and (RPI BOOT) to ON to enter BOOT mode.
As shown in the following figure is for PI4B_Adapter.
For other motherboards, refer to the CM4 eMMC part of the motherboard manual to set the switch.
For some motherboards (e.g. Manta-E3EZ, Manta-M8P-V1.1, Manta-M5P) with OTG/UART selector switch for Type-C, we also need to set the switch to OTG mode according to motherboard's manual -
USB driver for windows (Linux skip this step): refer to the official website of AllWinner
- Download Zadig to the rescue
- Enable
Options->List All Devices
- Select the USB device to install the driver(most likely will be "unknown"). Make sure the device USB ID is "1F3A:EFE8"). Click
Install Driver
after confirming that the information is correct
-
Open the
Powershell
(windows) orconsole terminal
(linux) where you downloaded the sunxi-fel tools and CB1 driver in step 1. -
Run
.\sunxi-fel.exe -v ver
(windows)
sudo ./sunxi-fel-armhf -v ver
(linux-armhf)
sudo ./sunxi-fel-aarch64 -v ver
(linux-aarch64)
to check whether the USB of CB1 is connected normally.
If you getERROR: Allwinner USB FEL device not found!
means that the USB is not recognized. Please recheck whether the driver is installed successfully.
If you getAWUSBFEX soc=00001823(H616)
means that CB1 eMMC is ready.Here on the first line is an example of error you will see if the driver did not install correctly. On the second line is an example of what it will look like after zadig has installed the driver correctly.

Run
.\sunxi-fel.exe uboot .\u-boot-sunxi-cb1-emmc.bin
(windows)
sudo ./sunxi-fel-armhf uboot ./u-boot-sunxi-cb1-emmc.bin
(linux-armhf)
sudo ./sunxi-fel-aarch64 uboot ./u-boot-sunxi-cb1-emmc.bin
(linux-aarch64)
to write u-boot to CB1 -
When the uboot is written, the computer will recognize a USB flash disk, and then you can use
balenaEtcher
orRaspberry Pi Imager
to write the OS image to eMMC. The steps are the same as the SD card version. -
