MPC8548 Problem with Jumbo Packets

Hello!!

 

I have a problem sending larges UDP messages with a MPC8548.

 

After configuring all registers properly (i think), when i send a message with more than 2005 bytes, the message doesnt reache the PC who is waiting for.

 

I had to change the value of the following registers for this:

  - MAXFRM = 0x00002580 (9600 bytes)

 - MACCFG2 =0x00007105

 - Flags of packet: 0xBA82 (WRAP), 0x9A82 (without WRAP)

 

Any idea?

 

Thank you in advance,

Diego.
