DP83848K driver compatibilty with DP83848C

Other Parts Discussed in Thread: DP83848K, DP83848C

Hello,

I am currently trying to run the existing board with LPC1788 and the PHY DP83848K. The project is developed using Keil uVision 5. I am trying to use peripheral drivers delivered by Keil, but there is only PHY DP83848C driver available. I modified already the header .h file according the DP83848K datasheet. I don't know if there are some changes required as well in .c file of the driver.

Maybe some can give me a hint how to run that chip or has already such a PHY driver prepared and can share?

BR,

Krysztof,

From the perspective of PHY operation, the DP83848C and the DP83848K are functionally equivalent. One difference between the devices is that the DP83848C supports interrupts. I am not familiar with the peripheral drivers from Keil. If these drivers perform basic functionality and do not rely on the interrupt functionality of the DP83848C, they might work for the DP83848K as well.

Thank you Patrick. I do not see any calls in .c file that refer to the MII interrupt registers definitions. So the driver is probably good for K profile as well.
