RTOS/AM4376: NIMU basic example

Part Number: AM4376

Tool/software: TI-RTOS

Hi,

I'm trying to get any network example to work on the EVM. But no luck.

I Imported the NUMU_BasicExample_evmam437x to CCS V7, and it compiled with no issues. However when I try to run it, I get the following output:

SetPhyMode:000021e1 Auto:1, FD10:64, HD10:32, FD100:256, HD100:128, FD1000:8192 LPBK:0

SYS/BIOS Ethernet/IP (CPSW) Sample application, EVM IP address: 192.168.2.40
ENETPHY_FindingState: Timed Out looking for a Phy!
ENETPHY_FindingState: Timed Out looking for a Phy!
ENETPHY_FindingState: Timed Out looking for a Phy!
ENETPHY_FindingState: Timed Out looking for a Phy!

Is there anything else I should do to make it work?

Is there any practical documentation or tutorial to setup RTOS network on the am437x?

Thanks!

shai

    Shai,

    Are you able to ping the board with IP address 192.168.2.40?
    Are you using the latest Processor SDK 4.2?
    Which Ethernet port is connected? And was the board connected to a router or PC NIC?
    There is no dedicated document for the RTOS network setup on AM437x, but the EVM quick start guide www.ti.com/lit/ml/sprw256/sprw256.pdf may help isolate any issue with your EVM.

    Regards,

    Hi Garrett,

    Thanks for your quick response!

    I'm using SDK ver: 04.02.00.09
    tried connecting both ports to a router, but got no ping. The ip is static and within the router network of 192.168.2.xxx
    Single stepping the program, it seems it is stuck on:
    enet_phy.c:
    if( CSL_MDIO_isPhyAlive((CSL_mdioHandle) ((ENETPHY_DEVICE *) hPhyDev)->miibase, i))
    it never return true. value of hMdioRegs->ALIVE_REG is 0x30 (address of hMdioRegs is 0x4A101000)

    for some reason this polls only phy address 0 (first port). Can it scan the other port as well?

    I will take a look at the quick start guide.
    BTW, when I tried running Linux on the EVM, the network worked fine, so the HW is probably ok.

    Thanks again,
    shai

    Hi Again,

    OK, I think I know whats wrong, My board is the sk and not the evm. Will try the correct example and let you know. sorry for that.

    And Hi yet again.

    Yes it was all my fault, I thought that I was working with the EVM but actually it was the SK, now the examples seems to work fine.
    Thanks for all the help - the link to the quick guide doc you gave made me realize I'm using the wrong board.
    Sorry for everything.

    shai
