TMS320F28388D: UDP fragmentation

Part Number: TMS320F28388D


Hello,

In my previous post, I got confirmation that UFO was not implemented in HW.

I have one Ethernet packet that I need to manually fragment (2 fragments) as it is bigger than the MTU on my link.

Once again, the TRM is not clear because it seems the EMAC IP documentation has not been properly adapted to its implemetation in the TMS320F28388D so I am not sure how I should handle the fields in the TDES3 descriptor.

Should I be setting the TSE field for the first packet descriptor ?

What should I put in the TPL field for the two packets ?

Please advise,

Best regards

Clément
