TSE_MAC to pc

hi:

if I want to realize translation from the data in memory on chip to PC through RJ45,The steps I do as follows:

1: sopc system: on chip memory->SGDMA_TX->TSE_MAC to PHY then to RJ45.

2: in niosII elipse,software process is :

open and reset :SGDMA_TX/RX ,

reset :MAC_TSE

set : MAC_TSE registers and MAC address

set :PHY speed and duplex mode

enable :MAC_TSE and SGDMA_TX

when the software code runs to the part of "set MAC_TSE registers".the process stop running,I donnot know why cannot set MAC_TSE register??

    you could debug your code to see if you are stuck in a loop or if it is the hardware that is stalling the CPU. If it is the latter, check that the TSE is receiving all its clocks (including the ones on the PHY side).

    thanks,

    the problem is still there ,I suspect that the reason is the corresponding registers of PHY chip(DP8384c) has not been set.

    because I write code using API which provided by TSE_MAC ,so I refer the

    altera_avalon_tse.h, altera_avalon_tse.c,the codes in these files are not simple,so ,I donnot know how to utilize them.and donnot know which registers of PHY should be set.

    I can send you the code I write ,and discuss with each other!~
