Hi all,
I ported U-Boot 1.3.1 on Avnet MiniModule-FX12 (the repository I'm working with has been patched previously with ML403 patch). Here is my first dirty patch:
http://www.dave.eu/download/misc/mmfx12/mmfx12-0.8.3.patch
U-Boot works fine and it boots correctly from flash, however ethernet interface (LL_TEMAC) does not work. For example, when I try to perform a TFTP download, the XEmac_PollSend function never returns because the following loop never ends:
/* * Loop on the MAC's status to wait for the transmit to complete. The * transmit status is in the FIFO when the XMIT_DONE bit is set. */ do { IntrStatus = XIIF_V123B_READ_IISR(InstancePtr->BaseAddress); } while ((IntrStatus & XEM_EIR_XMIT_DONE_MASK) == 0);
Please note that the FPGA bitstream is ok because the linux kernel works fine and can mount root file system via NFS so I pretty sure something is wrong in my U-Boot port.
Anybody experienced similar problems?
TIA, llandre
