We have modified out FPGA design and now we have LL_TEMAC with LL_DMA component connected instead of the LL_FIFO. Before building linux kernel we have tried to build the u-boot (downloaded from the xilinx-git tree). It was relatively easy to build u-boot which has the ll_temac with ll_dma support. next we have tried to run u-boot on our ppc (virtex-4 FX12). All went fine till the moment to establish the communication with the network. I put some debug messages to the xilinx ll_dma and ll_temac drivers and we have found that u-boot hangs during dma initialisation: more specifically in the function calls : XLlDma_Initialize(XLlDma * InstancePtr, u32 BaseAddress) XLlDma_Reset(XLlDma * InstancePtr) XLlDma_mBdRingSnapShotCurrBd(TxRingPtr); Do you have any idea what could be wrong with dma initialization?
