AM263P4-Q1: Enet CPSW Large Pool Packet Size

Mari Tsunoda

Part Number: AM263P4-Q1

Tool/software:

Hi Team,

My customer tried to change the large pool packet size from 1536 to a smaller value, in the Enet(CPSW) Packet Pool Config, but it shows an error saying "Assertion @ Line: 410 in syscfg/ti_enet_lwipif.c: pPktInfo != NULL : failed !!!"

It also seems like the ti_enet_lwipf.c file is causing an error at packet allocate and therefore pPktInfo == NULL occurs. Is there no way to change the large pool packet size?

Best regards,

Hi Mari,

Please follow this guide to correctly re-size the packet pools: software-dl.ti.com/.../PACKETPOOL_CONFIG_TOP.html

Hi Shaunak,

So to confirm my understanding, they should also check the box for "Enable Custom Rx Buffer Size" and enter the smaller size they input as large pool packet size into the "Rx Packet Buffer Size" as well?

Best regards,
