[U-Boot-Users] LL_TEMAC on Avnet MiniModule-FX12

[U-Boot-Users] LL_TEMAC on Avnet MiniModule-FX12

[llandre]

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

Hi Llandre,

that's why you use opb_emac driver for ll_temac. That's all. Different driver
and different ip_core.

Regards,
Michal

I see. I erroneously understood that this driver supports every (t)emac 
flavours.

Thanks for your help,

> What repository are you working from?
U-Boot 1.3.1 cloned last February.

> What ML403 patch are you referencing?
http://www.dave.eu/download/misc/mmfx12/ml403.patch
This derives directly from this old patch that has been around since 2005:
http://www.dave.eu/download/misc/mmfx12/4-ml403.2005-10-01.patch
This patch has been applied by my colleague. Then I put my hands on 
repository and started working on MiniModule port.

Thanks for your availability.

We did the same. First we worked on the ML403, then we ported our 
project to MiniModule that will be the base for the final application.
