I have implemented QJ Wang's LwIP FreeRTOS example on a TMS570LC4357 HDK and am having an issue that is hard to resolve. To set up the project for building I had to
- Modify HL_emac.c on line 1760 to enable EMACTxIntISR and EMACRxIntISR
- cd ~/ti/Hercules && git clone https://git.ti.com/git/hercules_examples/hercules_examples.git
- Updated ${workspace_loc:/${ProjName}/example and ${workspace_loc:/${ProjName}/lwip-1.4.1 directories to point to ~/ti/Hercules/hercules_examples...
Over terminal I can see
HERCULES MICROCONTROLLERS
Texas Instruments
Little Endian device
Initializing ethernet (DHCP)
DEBUG - Getting PHY ID....SUCCESS
DEBUG - Getting PHY Alive Status...SUCCESS
DEBUG - Getting PHY Link Status...SUCCESS
DEBUG - Setting up Link...SUCCESS
The program hangs in EMACTxIntHandler on line 1538:
while(((EMACSwizzleData(curr_bd->flags_pktlen)) & EMAC_BUF_DESC_OWNER) == EMAC_BUF_DESC_OWNER)
{
}
I have read some posts about this issue but they have not helped so far.

I understand that Asina-Chie-Shih-Shuai has put up quite a few helpful posts on this topic and may be able to provide some input. My project is attached.
