MCF5235 Pin Config

[mcf5235]

Hello,

Can someone let me know, whats the default pin config for the eTPU on MCF5235 board.It has got 32 channels of which the upper 16 channels are multiplexed with Etherner Controller. So, by default is it totally eTPU? or do we need to program it to use all the 32 channels.

Thanks a lot in advance

    Hello,

The eTPU/EthENB pin configures wich modules are available to the user and selects the muxing of the eTPU Channels (16 - 31) and Ethernet Controller.

• eTPU/EthENB pin High selects eTPU Channels (16 - 31).
• eTPU/EthENB pin Low  selects Ethernet Module.

Bye

Hi,

Do you (or anyone else) know of any way that software can read the level of the eTPU/EthENB pin (M4 on the MCF5235) and thereby determine whether Ethernet or 32 channel TPU has been selected at boot time.

Best wishes,

Ahlan

Hi,

On the evaluation board you have to manage the pin M4 by Switch 7  pin 11. On is Ethernet - OFF is eTPU(16-31).  Zhis is the eTPU/EthEN configuration input pin.

Have a nice day

Hi all,

I couldnt use the 32 channels on my board as they are hardcoded as ethernet port...its a CMM5235 but not a 5235EVB.

That was the prob.

Thanks a lot
