TMS320C6657: NDK can't sendto 10240 bytes

Shine

Part Number: TMS320C6657

Hello Champs,

BIOS_MCSDK_2_1_2_6

NDK_2_23_02_03

pdk_C6678_1_1_2_6

Bios_6_33_06_50

xdias_7_21_01_07

xdctools_3_23_04_60

Compiler c6000_7.4.4

Customer modified NDK to sendto 10240 bytes according to Enabling Jumbo Packet Support for C6678” and “Rebuilding The NDK Core Using Gmake - Texas Instruments Wiki". He can't catch any packet via wireshark. But the 1024 bytes can work.

Code is stuck in continue，can't reach Line 771。

Customer also modified code according to below post.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/107053/pbm_alloc-for-transmit-packets

The issue still exists.

Besides, after adding _INCLUDE_JUMBOFRAME_SUPPORT, it can't 1024bytes which works before.

Thanks
Regards

Shine,

Would you please confirm that the customer has done the following,

1. The libraries and application would have to be recompiled with the following pre-processor definition added: _INCLUDE_JUMBOFRAME_SUPPORT.

2. The Jumbo frame support can be built into an application by linking with libraries compiled for Jumbo frame support.

( The NDK core stack can support Jumbo frames (packet sizes larger than 1500 bytes) also -

_INCLUDE_JUMBOFRAME_SUPPORT -- If defined, packet sizes larger than 1500 bytes are supported..

---

To rebuild the NDK, please download and follow the steps given here:-
