Hi has this issue been resolved?

we are working with imx8dxl and SJA1110 and require a clause45 driver for MDIO communication with the ethernet switch. to acces and controll the registers.

thats a pitty and also no solution.

 

we did however already patch the HW and added an SPI port to the switch which alowed us to readout the registers.

 

pitty that after 3 weeks still no solution availeble.

pls close the case.
