Hello All,
When I boot from NFS, it doesn't work, so I boot system from NOR flash.
I found FEC hasn't produced any interrupts ( of course, I have plugged
in cable, and make sure the cable works on other boards, what's more, I
can see FEC light blinks)
when system boot up:
-sh-2.05b# cat /proc/interrupts
CPU0
16: 0 IPIC Level fs_enet-mac
17: 36 IPIC Level i2c-mpc
18: 1 IPIC Level i2c-mpc
19: 1 IPIC Level i2c-mpc
40: 1117 IPIC Level mpc512x_psc_uart
BAD: 0
-sh-2.05b# ethtool eth0
Settings for eth0:
Supported ports: [ TP AUI BNC MII FIBRE ]
Supported link modes:
Supports auto-negotiation: No
Advertised link modes: Not reported
Advertised auto-negotiation: No
Speed: 10Mb/s
Duplex: Half
Port: MII
PHYAD: 1
Transceiver: external
Auto-negotiation: on
Current message level: 0x00000000 (0)
* Link detected: n*
it seems very strange that link detected is no, I have tried the kernel
uImage from Freescale ISO, the thing is same to above.
The part of DTS as bellow:
[EMAIL PROTECTED] {
device_type = "mdio";
compatible = "fs_nocpm_enet";
reg = <2840 4>;
#address-cells = <1>;
#size-cells = <0>;
phy: [EMAIL PROTECTED] {
// interrupt-parent = < &cpld_pic >;
// interrupts = <b 8>;
reg = <1>;
device_type = "ethernet-phy";
};
};
[EMAIL PROTECTED] {
device_type = "network";
model = "FEC";
compatible = "fs_nocpm_enet";
device-id = <1>;
reg = <2800 800>;
address = [ 00 E0 0C BC E5 40 ];
local-mac-address = [ 00 E0 0C BC E5 40 ];
interrupts = <4 8 >;
interrupt-parent = < &ipic >;
// NOTE: for 7-wire, remove phy-handle
// and add seven-wire
phy-handle = < &phy >;
//seven-wire;
};
when boot from NFS, some information as belows:
011400.serial: ttyPSC1 at MMIO 0x80011400 (irq = 40) is a MPC52xx PSC
