DP83826E: DP83640 port to DP83826E

Part Number: DP83826E
Other Parts Discussed in Thread: DP83640, TMDS570LS31HDK, HALCOGEN,

Hello TI,

I am looking how to port a code which is already written for DP83640 on hercules EVM (TMDS570LS31HDK) with support of Halcogen. 
As I checked halcogen doesn't support for DP83826E. Please me know what changes needs to be done in terms of software to make a halcogen generated code of DP83640 to work with DP83826E.

Both are in MII configuration.

The controller used is TMS570LS3137


Thank you

    Hi Adarsh,

    We never got this requirement before,

    what we have to verify here is, we have to compare register and bit locations of driver files(phy_dp83640.c and phy_dp83640.h) generated for 83640 generated by HALCoGen with the register and bit locations of 83826E.

    If they are identical then we no need to make any software changes otherwise we should correct the driver file.

    Hello Jagdish,

    The registers of the 2 phy differs. I have made a list of the same for comparison.
    I wanted to know how to integrate changes if we have a register which is not defined in the other phy.
    Is there anyway in which halcogen can generate DP83826E driver.

    Hi Adarsh,

    No, It is not possible because HALCoGen doesn't have support for DP83826E. We have to manually should make the changes in driver files.

    Take a copy of the driver files and try to include the changes in user code sections or else have to create the complete new driver files.
