NUC980DK61Y PB.2 UART9_RTS UART9 request to Send ouput pin But make menuconfig NUC980 UART9 pin selection (x) Rx:PB3, TX:PB1 ( ) RX:PE8, TX:PE7 ( ) RX:PE10, TX:PE12 ( ) RX:PE6, TX:PE7, RTS:PE5, CTS:PE4

can't config RTS:PB2

Hi,

We only open the config pin combinations supporting both CTS and RTS in Kconfig. You can add 0x12 to uart9_0_pins[] arrary defined in pinctrl-nuc980.c to support PB2 RTS by select "(x) Rx:PB3, TX:PB1"

Sincerely,

Yi-An Chen

like this? static const unsigned uart9_0_pins[] = {0x11, 0x13}; // tx, rx static const unsigned uart9_1_pins[] = {0x12, 0x44}; // rts, cts static const unsigned uart9_2_pins[] = {0x45, 0x44}; // rts, cts static const unsigned uart9_3_pins[] = {0x47, 0x46}; // tx, rx static const unsigned uart9_4_pins[] = {0x4C, 0x4A}; // tx, rx

No, like this: -static const unsigned uart9_0_pins[] = {0x11, 0x13}; +static const unsigned uart9_0_pins[] = {0x11, 0x12, 0x13};

And keep the rest untouched.
