ethernet for ls1046

gie_yang — Thu, 04 Jan 2024 02:52:59 GMT

Hi All：

We have currently designed a motherboard based on LS1046 and I want to connect Ethernet PHY RTL8211FS, which uses RGMII and SGMII MAC interfaces. The PHY RTL8211FS chip cannot be correctly identified by using "mii info" on the uboot terminal, but the device name "fm1-mac*" can be identified by logging in to linux. Log as follows:

=> mii info
PHY 0x00: OUI = 0x0000, Model = 0x00, Rev = 0x00, 10baseT, HDX
PHY 0x01: OUI = 0x0000, Model = 0x00, Rev = 0x00, 10baseT, HDX
PHY 0x02: OUI = 0x0000, Model = 0x00, Rev = 0x00, 10baseT, HDX

root@localhost:~# ifconfig -a
fm1-mac3: flags=4098<BROADCAST,MULTICAST> mtu 1500

TX packets 0 bytes 0 (0.0 B)

Now, the ping itself is now normal when tested with the fm1-mac* device.

However, the ping test between the LS1046 board and the PC fails when the PC is directly connected to the PC using a network cable.

The SDK version we are currently using is LSDK1906
Can anyone give me some help about this problem?

Please refer LS1046ARDB LSDK2108 to merge new PHY as there are both RGMII and SGMII PHYs on board.

From code review, you can modify those files as below:

u-boot:

u-boot\board\freescale\ls1046ardb\eth.c

u-boot\include\configs\ls1046ardb.h

#ifdef CONFIG_NET

#define CONFIG_PHY_REALTEK

#endif

#ifdef CONFIG_SYS_DPAA_FMAN

#define RGMII_PHY1_ADDR 0x1

#define RGMII_PHY2_ADDR 0x2

#define SGMII_PHY1_ADDR 0x3

#define SGMII_PHY2_ADDR 0x4

Kernel:

dts

kernel menuconfig to enable driver of realtek phy

Hi June_Lu,

I have modified it in these files before, but I got the same result.

u-boot:

u-boot\board\freescale\ls1046afrwy\eth.c

u-boot\include\configs\ls1046afrwy.h

#ifdef CONFIG_SYS_DPAA_FMAN
#define CONFIG_FMAN_ENET

//add gie-ls1046a
#define RGMII_PHY1_ADDR 0x1
#define RGMII_PHY2_ADDR 0x2
#define SGMII_PHY1_ADDR 0x3
#define SGMII_PHY2_ADDR 0x4
#define SGMII_PHY3_ADDR 0x5

u-boot/configs/ls1046afrwy_tfa_defconfig
CONFIG_PHY_REALTEK=y

Please carefully compare difference between the LS1046ARDB and customer board, and then update the driver and debug according to the customer board. And check if HW works correctly.

Has the issue been resolved? I am experiencing the same problem.
