STM32 P107 Olimex and RTX Keil kernel

Hi everybody,

I really hope you can give me a help with the following question:

I have an Olimex STM32 P107 board and I want to use the RTX Kernel from Keil using the uVision compiler. The problem is the PHY Controller, a STE101P, for which there is no driver provided in the ARM Keil compiler package. From the Olimex site I can download a driver, but this is used along with uIP stack and IAR compiler. I checked some similar driver in the Keil directory from other manufacturers, but I couldn't find any similar. Porting the driver is not an easy task. First, I would like to get any tips from you, otherwise I have to dig into the code and see how much I can do. Thanks in advance,

''Porting the driver is not an easy task''

Why not?

The PHY register sets are pretty similiar, you could probably use the examples from here, which use the same micro, or at least the same Ethernet peripheral:

C:\Keil\ARM\Boards\ST\STM3210C-EVAL\RL\TCPnet

C:\Keil\ARM\Boards\Keil\MCBSTM32C\RL\TCPnet

Compare the register map of your PHY with the one used on the STM3210C-EVAL and MCBSTM32C and I bet it's almost identical. The examples above might just work unchanged.

Thanks a lot for the help. I really appreciate it. I said ''not easy'' just because I thought I had to change to much the code, but after having a look in details I see that they look similar.

Cheers,
