Use "ethtool -S eth0" to dump the MIB counters from both sides to verify the host port connection is working properly. In the device tree the speed is set to 100. Is that intentional? I think the current DSA driver cannot handle that situation as it only looks at rgmii-id to configure the switch. The host port XMII control register has 2 bits for MII, RMII, or RGMII mode, then 2 bits for RGMII, RGMII_TX_ID, RGMII_RX_ID, and RGMII_ID mode, then 1 bit for 100/1000 operation. If that 100/1000 bit is needed for correct operation the driver has to manually change to set that bit.

Hi, I´ve tried with 1000 speed and the result is exactly the same. Also rigth now is flashed with 1000 speed. I leave here the ethtool output:

This "p06_rx_symbol_err: 1848" means the switch host port cannot receive properly from the MAC. You will need to try other RGMII delay combinations. It is a little weird as typically it is rx_crc_err with these types of connection issues.

Hi, I´ve been trying to read the switch registers via i2c just to asure that the configuration is correctly applied but I´m not able to do it via i2cget, do you know the way to do it properly?

I do not know how i2cget works. The most important thing about using I2C is the register width is 16-bit, so you need to supply 2 as a parameter if one is allowed. The I2C command from U-Boot can be used to access the switch if that function is enabled.

Hi, finally managed to read the registers via i2c and it seems to be confugred in default position (I looked register 0x7301 and the value is 0x08). Knowing this (there is minimum a 1.5ns delay in egress RGMII clock) , how should I configure the delay in MAC side as rxid or txid?
