NOTE: The CB1 eMMC version can also use the SD card as the OS image source, and the priority of the SD card is higher than on-board eMMC, so when using the eMMC, remember not to insert the OS SD cardĭownload the utility sunxi-fel to your computer (Mac OS is not supported) and download the CB1 driver NOTE: TFT35 SPI and MCP2515 multiplex a group of SPI1.uncomment overlays=spidev1_2 to release 'spidev1.2' to user space (For example: adxl345), spidev1.0 is used by MCP2515, spidev1.1 is used by tft35_spi.Uncomment overlays=mcp2515 to enable MCP2515 spi to canbus module (Theoretically, it can be multiplexed with tft35_spi and 'spidev1.2' at the same time, but mcp2515 needs strong real-time, it is better not to enable other SPI1 features when using mcp2515).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 and set the actual resolution.īTT-HDMI7 resolution = 1024圆00: resolution = 800x480: Uncomment overlays=tft35_spi to enable TFT35 SPI screen.If klipper wants to use UART0 to control the motherboard, we need to set it to console=serial, now klippe can use UART0 as /dev/ttyS0. We can use MobaXterm to connect to CB1 by UART0 and debug. The default value is console=display, This means that the UART0 of CB1 is used as the debugging port by default.
