Ethernet Issue on DSP/BIOS for TMS328TCI6488

Have you checked your memory map are they conflicting?  Also maybe there some conflicting resources like Timer?

There's not enough information here to determine what could be going on?  Is the Ethernet running on Core 0?

Hi judahvang,

Thanks for the reply.

Yes Ethernet is running on core 0.

I want to load you with few questions.

1.what exactly you mean by "Is your memory map conflicting"

2.Which registers are responsible for Ethernet status UP/DOWN or which part of the code tells about this.we can see PHYREG_read(PHYREG_1000CONTROL,pd->phyaddr).we are not able map these registers in datasheet. Also how we can find the linkstatus of the phy registers.

3.In helloworld sample code in file Cls_mdio.c i found it goes to MDIO_timerTick function to check the link or execute  the different states of state machine for getting the link status. After executing several steps it finally reaches to "PHYSTATE_LINKWAIT"  and when we run it on debug mode it goto ChekTimeout evertime rather it should go to the next step i.e. RetVal=MDIO_EVENT_LINKUP.
So my question is why timeout is being occurred and why it is not going to the next state.
Can you give the detail about the timeout related to this scenario.

4.In Evminit.c file we have phy_setReg(0xe,26,0x47) what are these parameters stand for.we couldnt map it.

5.How we can confirm that phy registers are set,read,write succussfully.

Judahwang Your support will be highly appreciated as our project is in a very criticle stage.

Hi venkat rao,

Which version of the NDK are you using?

Are you working with a Software Development Kit (SDK) of some sort?  If so, do you know which SDK and its version?

Steve

The H/w and S/w Component details are given below.

EVM (board) : TMS320TCI6488
NDK : 2.0.0
CCS : 3.3.38.2
BIOS : 5.41.03.17

Problem statement : The Ethernet link comes up and the Tx Interrupt has been initialized and can be observed in operation the Receive interrupt is not occurring.


Observation / Queries:

 (a) The below mentioned files and libraries have bee provided by TI and the location from where these are being included in our project has been
also mentioned for your benifit.
   Files :csl_emac.c , csl_mido.c , evminit.c ,
   Src Location : c:\ccstudio_v3.3\ndk_2_0_0\packages\ti\ndk\src\hal\tci6488\eth_c6488

(b) The following libraries are being included in the project.
Library names :csl_c6488,csle.lib,hal_eth_c6488,hal_ser_stup,hal_timer_bios, hal_userled_stub.lib,miniPrintf.lib,netctrl.lib,nettool.lib,os.lib,statck.lib
 
   We require the source code of the libraries so we can individually build in the project and it provides us with more scope of debugging. Also any pointer
to the methodology for compiling these source files into libraries.

(c)There are registers we are writing to and reading using the user access registers. The user access register takes a phy address and a reg number
      as an argument, The information for  How does the reg number map to which register in the data sheet is not there thus we do not know which are the registers
      we are accessing via mdio user access register.

(d)The Tx Interrupt is being generated in our code as EMAC_TxServiceCheck is being called from the ISR. We are currently unable to place a breakpoint in the receive ISR
      as it is in a library and EMAC_RxServiceCheck fuction is never called thus the receive ISR is not being hit even when the Ethernet Link has already come up and a ping has been    initialized from a connected station..
    From the function header of  EMAC_RxServiceCheck we could make out that the intialization of the Interrupt and hooking of the ISR to the interrupt is being done separately.
    Can you please point us to it is being done in which library and we want to ensure that the Rx interrupts are initialized correctly.

   Please let me know if  additional inputs are required from our side.
