1G Ethernet detection on RZN1D platform

Question

Hi, 
 
 We are using custom board based on RZN1D platform. I wanted to configure the 1G PHY (vsc8531) from CM3 core. We have used VSC8531 Ethernet PHY for 1G Port. I have modified the " 00410_goal\eth_state_ctc_cc " example code and able to detect the default PHY ID of VSC8531. To make sure the 1G PHY is working correctly i wanted to ping from system/ PC. I have used the another project " goal_eip_lib\02_dlr_dhcp " for this but unable to debug the functionality because only .h (header) files are included in project. 
 1) which example code i have to use to check ping functionality of Ethernet? 
 2) How to set the IP address of RZN1D board? 
 3) How to debug the GOAL project which have only .h files? 
 
 Please help me to resolve the issue.

Hi Mayur, 
 the first error log about invalid config size just informs the user, that the application CM variables and the CM variables detected at NVS do not match. This happens when adding new CM variables, switching protocol, or starting application, which does not write into NVS. 
 I suggest following debug steps to get further information of the system : 
 - add Break Point 0 (BP 0) at goal_tgtEthRxTask:{703: &ldquo;if ((E_OK != ercd) || (0 == flags)) {&ldquo;} 
 - add Break Point 1 (BP 1) at goal_tgtEthTxTask(1374: &ldquo;res = goal_maEthSendFrameGetCb(pMaInst, &pBuf);&rdquo;) 
 &agrave; If BP 0 is triggered, incoming frame has passed PHY, MAC and switch successfully. 
 &agrave; If BP 1 is triggered, the response frame has been created by GOAL and will be forwarded to switch for transmission. 
 &agrave; If BP 0 is triggered nor BP 1, continue session step by step to detect the point of frame discarding. 
 &agrave; If neither BP 0 nor BP 1 is triggered, pause debug session at any time after ping requests have been transmitted and check switch/ MAC registers. (I suggest disabling any network interface setting on Windows PC beside IPV4 or usage of Linux or Raspberry Pi to exclude network traffic other than required for ping-process. 
 In addition, Wireshark is helpful to validate network traffic.) Are there any counter registers of relevant port(s) increased? If no, frames might be discarded in PHY. Read PHY error registers to check status. 
 BR, Andreas
