Hi
I'm hoping a list member could offer some advice setting a UART with a
custom speed.
I was hoping to calculate the required divisor and use setserial to set my
speed (100000), however both Python's pySerial and the "setserial" command
cause the following error:
[root@A20-SOM ~]# setserial /dev/ttyS1 spd_cust
[ 697.027655] dw-apb-uart 1c29800.serial: setserial sets custom speed on
ttyS1. This is deprecated.
[root@A20-SOM ~]#
Deprecated in favor of?
I had a look in the dts:
uart6: serial@01c29800 {
compatible = "snps,dw-apb-uart";
reg = <0x01c29800 0x400>;
interrupts = <0 19 4>;
reg-shift = <2>;
reg-io-width = <4>;
clocks = <&apb1_gates 22>;
status = "disabled";
};
...however I don't understand the relationship between "22" and
"&apb1_gates"
How do I set the divisor and/or configure my custom speed of 100000 for my
UART6?
Thanks
Bruce
