[U-Boot-Users] What is wrong with "fec: rx error 0c10"?

[Hiroshi DOYU]

Hi all,

I am struggling with porting u-boot on the custom board which is based 
on PQ2FADS_VR(MPC8670). Though I could ping to host from the target board, 
I got the following error when downloading the image from host through 
"tftpboot", which I had make sure that freescale evaluation board could 
work correctly. 

According to the spec document, the error message "fec: rx error 0c10" 
means, BD_ENET_RX_NO, CRC check error in RxBD offset 0x0. I could not 
get what this message means correctly in this case and where I should 
look into it deeply. So it would be appricited if you tell me where 
I should look into deeply.

Thanks,

Details:
- FCC1, 2 were connected PHY LXT971A each.
- CONFIG_BITBANGMII was defined.
- CFG_MDC_PIN/CFG_MDIO_PIN were configured.
- u-boot is updated from CVS.
