DP83848K: Need the packet sending instructions for this PHY chip.

Hi,

DP83848 is an older part with limited support. Are you able to switch to DP83826A instead?

Can you elaborate what you mean by 'Packet sending instructions'?

Best,

Shane

Hi,
Thank you for your reply. We are requesting the test command for the 100M Ethernet PHY (eye diagram).
Instructions similar to this one：
echo "1,31,0xA412,0x200" > /sys/module/realtek_822x/parameters/para
/sys/module/realtek_822x/parameters/param
set
page=31 reg=0ха412 to 0x200 ok
/sys/module/realtek_822x/parameters/param
echo "1,7,0x0000,0x3000" > /sys/module/realtek_822x/parameters/para
set page=7 reg=0x0 to 0x3000 ok

Hi Shane

We need to be capable of meeting this requirement.

Hi Ruiqi,

Thanks for clarifying. For 100Base-TX compliance test, you just need to force the device speed to 100Mbps.
You can do so by: 0x0000 = 0x2100 // force to 100Mbps

Best,

Shane
