Other Parts Discussed in Thread: AM2432, SYSCONFIG
Tool/software:
Hi,
I have a custom board using AM2432_ALV. The board uses DP83867IRPAPT on CPSW0 RGMII interface. I am only using MAC port 1. I have modified the example 'enet_cpsw_udp_igmp_am243x-evm_r5fss0-0_freertos_ti-arm-clang' and all builds fine. The problem is nothing comes out of the MAC Tx interface but the 125MHz clock. I can se the RGMII interface come to life in the PHY->MAC direction but it seems as if something is wrong in the SDK regarding the Tx direction. It seems as if there is no negotiation going on at all from the MAC side no ARP and consequently no DHCP. If I switch to static IP assignment the debug UART output indicates all is fine but it is not! Not being an experienced SW guy I have searched this forum for this error and it seems there has been bugs in this code historically. Is this something you can shed some light on? I am sharing the debug output and the CPSW pin config.
Static IP debug output: (Network Falsely indicates 'UP')
DHCP IP debug output (Network never goes 'UP')
CPSW pins from sysconfig
Best regards
Jens
