Hello, I'm trying to get UART6 to work correctly in CM3-io Everything apparently works, but this error is recorded in the system log:
[ 8459.681893] ttyS6 set divisor fail, quot:13 != dll,dlh:0 [8605.569865] dw-apb-uart fe6a0000.serial: got rx and tx dma channels [ 8605.569936] ttyS6 set divisor fail, quot:13 != dll,dlh:0
Here the DTS for the Uart6:
` /dts-v1/; /plugin/;
/ { metadata { title = "Enable UART6"; compatible = "rockchip,rk3568,radxa,cm3-io"; category = "misc"; exclusive = "GPIO1_D5", "GPIO1_D6"; description = "Enable UART6.\nOn Radxa CM3."; };
fragment@0 { target = <&uart6>; __overlay__ { status = "okay"; rockchip,serial-id = <6>; pinctrl-names = "default"; pinctrl-0 = <&uart6m1_xfer>; }; }; fragment@1 { target = <&uart6>; __overlay__ { status = "okay"; }; };
}; `
`
dtoverlay=rk3568-uart2-m0 dtoverlay=rk3568-uart6-m1 dtoverlay=rk3568-disable-npu dtoverlay=rk3568-i2c2-m1 dtoverlay=rk3568-dwc3-host intfc: i2c2=on intfc: uart6=on intfc: uart2=on `
Where is the problem?
