[T1040RDB] l2sw_bin -> Failed to open /dev/l2sw_phy

[nicolaskury]

Hi

I have a T1040RDB with image-core sdk 1.8.  I can run l2sw_bin, it works but I see some errors.  Why ? Is it important ?

root@t1040rdb:~# l2sw_bin

Using UIO: /dev/uio16

Mapped register memory @ 0x3fff9da00000

Chipid: 099530e9

I have noticed these logs when I start Linux :

phy_0: Failed to get irq number - 0

phy_1: Failed to get irq number - 0phy_2: Failed to get irq number - 0

phy_3: Failed to get irq number - 0phy_4: Failed to get irq number - 0

phy_5: Failed to get irq number - 0phy_6: Failed to get irq number - 0

phy_7: Failed to get irq number - 0S

Note: when I launch the board with the default image image-core sdk 1.7, I don't have these errors.

Thank you

The UIO switch driver seems to be missing. Userspace switch control software uses it to access the switch registers. Make sure uio-seville kernel module

is built and installed. Refer to SDK 1.8 User's Manual, Section 8.3.1.2

Have a great day,

Hi

the module was already running. When I stoped and run it again, I've got:
