P2020 srio dtb setting，yocto1.7 ,help needed

tianli1 — Tue, 20 Jan 2015 13:19:25 GMT

dear experts!

I want to add srio to linux kernel for my customized P2020 board!

I am using yocto 1.7, my modification of dtb are as follows:

a)in p2020rdb-pc.dtsi, i added rmu:

rmu: rmu@d3000 {

#address-cells = <1>;

#size-cells = <1>;

compatible = "fsl,srio-rmu";

reg = <0xd3000 0x500>;

ranges = <0x0 0xd3000 0x500>;

message-unit@0 {

compatible = "fsl,srio-msg-unit";

reg = <0x0 0x100>;

interrupts = <

60 2 0 0 /* msg1_tx_irq */

61 2 0 0>;/* msg1_rx_irq */

};

message-unit@100 {

compatible = "fsl,srio-msg-unit";

reg = <0x100 0x100>;

interrupts = <

62 2 0 0 /* msg2_tx_irq */

63 2 0 0>;/* msg2_rx_irq */

};

doorbell-unit@400 {

compatible = "fsl,srio-dbell-unit";

reg = <0x400 0x80>;

interrupts = <

56 2 0 0 /* bell_outb_irq */

57 2 0 0>;/* bell_inb_irq */

};

port-write-unit@4e0 {

compatible = "fsl,srio-port-write-unit";

reg = <0x4e0 0x20>;

interrupts = <16 2 1 11>;

};

b) in p2020rdb-pc_32b.dts

1.i added:

rio: rapidio@ffe0c0000 {

reg = <0xf 0xfe0c0000 0 0x11000>;

port1 {

ranges = <0 0 0xc 0x20000000 0 0x10000000>;

};

2. comment out pci0,pci1,and pci2.

c)in p2020si-post.dtsi

1. added:

&rio {

compatible = "fsl,srio";

interrupts = <48 2 0 0>;

#address-cells = <2>;

#size-cells = <2>;

fsl,srio-rmu-handle = <&rmu>;

/*sleep = <&pmc 0x00080000>;*/

ranges;

port1 {

#address-cells = <2>;

#size-cells = <2>;

cell-index = <1>;

};

because pmc is undefined ,so i comment out this line "sleep = <&pmc 0x00080000>;"

i guess linux kernel stoped at srio driver init, the console print are as follows:

fsl-l2ctlr ffe20000.l2-cache-controller: Entire L2 as cache, provide valid sram address and size

fsl-l2ctlr: probe of ffe20000.l2-cache-controller failed with error -22

Setting up RapidIO peer-to-peer network /rapidio@ffe0c0000

fsl-of-rio ffe0c0000.rapidio: Of-device full name /rapidio@ffe0c0000

fsl-of-rio ffe0c0000.rapidio: Regs: [mem 0xffe0c0000-0xffe0d0fff]

fsl-of-rio ffe0c0000.rapidio: bellirq: 57

fsl-of-rio ffe0c0000.rapidio: pwirq: 16

fsl-of-rio ffe0c0000.rapidio: /rapidio@ffe0c0000/port1: LAW start 0x0000000c20000000, size 0x0000000010000000.

Have figured it out!

1.i added:

rio: rapidio@ffe0c0000 {

reg = <0xf 0xfe0c0000 0 0x11000>;

the register is wrong ,it should be reg = <0x0 0xfe0c0000 0 0x11000>;

now kernel boots ok! the print are as follows:

fsl-l2ctlr: probe of ffe20000.l2-cache-controller failed with error -22

Setting up RapidIO peer-to-peer network /rapidio@0xffec0000

fsl-of-rio ffec0000.rapidio: Of-device full name /rapidio@0xffec0000

fsl-of-rio ffec0000.rapidio: Regs: [mem 0xffec0000-0xffed0fff]

fsl-of-rio ffec0000.rapidio: bellirq: 50

fsl-of-rio ffec0000.rapidio: pwirq: 48

fsl-of-rio ffec0000.rapidio: /rapidio@0xffec0000/port2: LAW start 0x0000000c20000000, size 0x0000000010000000.

fsl-of-rio ffec0000.rapidio: RapidIO PHY type: Serial

fsl-of-rio ffec0000.rapidio: Hardware port width: 4

fsl-of-rio ffec0000.rapidio: Training connection status: Four-lane

fsl-of-rio ffec0000.rapidio: RapidIO Common Transport System size: 256

/soc@ffe00000/rmu@d3000/message-unit@100: txirq: 55, rxirq 56

anybody knows how to use srio to write another device? how to develop the application?

Thank you Pavel Chubakov，I have a question about how to use rapidio demo on p2020.did there any demo about how to use rapidio on p2020 which use linux kernel 3.12.And I use Yocto SDK 1.8 。I found SDK only have a rionet demo and i want a demo which like rmu in usdpaa-apps? Did there any? Sorry for my little English!
