LP-AM243: MCU+SDK 8.5.0.24

Hi experts,

I am using the LP-AM243 version E3, MCU+SDK 8.5.0.24, and CCS 12.1.0.

I do not get the enet_lwip_cpsw example to work, the board does not respond to ping. Ethernet is connected to the PC on J19. A DHCP server is implemented on the PC. The example from MCU+SDK 8.5.0.24 has been working fine.

Please find attached the project.

What am I doing wrong?

Hi Alex,

We have started looking into the issue.

The debug output on the UART is:

==========================
ENET LWIP App
==========================
Enabling clocks!
Mdio_open: MDIO Manual_Mode enabled
EnetUdma_openRxCh: [Enet UDMA] UDMA RX Channel open failed: 0xffffffff
EnetHostPortDma_open: Failed to open Enet DMA RX channel: -1

Just to mention, I did two changes in the SDK code:

#define LWIP_DHCP 0

#define LWIP_PORT_INIT_IPADDR(addr) IP4_ADDR((addr), 192,168,39,5)
#define LWIP_PORT_INIT_GW(addr) IP4_ADDR((addr), 192,168,39,5)

... but the problem also exists without these changes.

Hi Alex,

Apologies for the delay. I could not reproduce the issue for SDK example.. Can you share the binary you are using.
