Dear Yordan Kovachev ,Ivan Matrakov and Biser Gatchev-XID:
Thank you very much your last guides for me! Forgive me .i 'm a beginner of linux.
I notice am335x-boneblack.dts inclding am33xx.dtsi and am335x-bone-common.dtsi.
In your opinion all uarts are configured in am33xx.dtsi . If i want to use uart1, i just need adding uart1_pins and enabling uart1 as following:
uart0_pins: pinmux_uart0_pins {
pinctrl-single,pins = <
0x170 (PIN_INPUT_PULLUP | MUX_MODE0) /* uart0_rxd.uart0_rxd */
0x174 (PIN_OUTPUT_PULLDOWN | MUX_MODE0) /* uart0_txd.uart0_txd */
>;
};
uart1_pins: pinmux_uart1_pins {
pinctrl-single,pins = <
0x170 (PIN_INPUT_PULLUP | MUX_MODE0) /* uart0_rxd.uart0_rxd */ In here 0x170 must be modifying to a right nummber
0x174(PIN_OUTPUT_PULLDOWN | MUX_MODE0) /* uart0_txd.uart0_txd */ In here 0x174 must be modifying to a right nummber
>;
};

ocp {
uart0: serial@44e09000 {
pinctrl-names = "default";
pinctrl-0 = <&uart0_pins>;
status = "okay";
};
uart1: serial@48022000 {
pinctrl-names = "default";
pinctrl-0 = <&uart1_pins>;
status = "okay";
};

Am i right?
In addition, after i finish modifying the .dts files.
I will compile .dts files to dtbo files by dtc tools.
The problem is what i should do in the next steps?
I mean how i should use .dtbo files?
You know the capemanager isn't supported in the ti-sdk-am335x-evm-07.00.00.00 .
It doesn't like in the Angstrom.
# cat /sys/devices/bone_capemgr.*/slots
0: 54:PF---
1: 55:PF---
2: 56:PF---
3: 57:PF---
4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G
5: ff:P-O-L Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI
Do i install a cape manager in the ti-sdk-am335x-evm-07.00.00.00 in any way? And after it I load the .dtbo files.
What should i do?
Thank you!
3xxx
