Summary: BF561-EZKIT rev 2.0, SCLK 120MHz/CCLK 600MHz, it fails to tftp download in u-boot.

Details:

 

For 08r1 branch and trunk, BF561-EZKIT rev 2.0, SCLK 120MHz/CCLK 600MHz, it fails to tftp download in u-boot.

TFTP download is ok on BF561-EZKIT rev 2.0 when use 07r1 u-boot.

For 08r1 branch and trunk, BF561-EZKIT rev 1.3, it's also ok.

 

Below I listed several combinations I tested.

tftp download

fail in:

    trunk, SCLK 120M, CCLK 600M, rev 2.0(ping failed)

    08r1 , SCLK 120M, CCLK 600M, rev 2.0

pass in:

    trunk, SCLK 100M, CCLK 600M, rev 1.3

    trunk, SCLK 120M, CCLK 600M, rev 1.3

    08r1 , SCLK 120M, CCLK 600M, rev 1.3

    08r1 , SCLK 100M, CCLK 600M, rev 1.3

    07r1 , SCLK 120M, CCLK 600M, rev 1.3

    trunk, SCLK 100M, CCLK 600M, rev 2.0

    08r1 , SCLK 100M, CCLK 600M, rev 2.0

    07r1 , SCLK 120M, CCLK 600M, rev 2.0

we already know that the usb lan addon card when used with the bf561-ezkit

cannot be run at SCLK larger than 100mhz due to hardware bugs

 

that is why the default is set to 100mhz
