CCS/LAUNCHXL2-570LC43: TMS570LC43X

Hi Padayappa,

There really is not an out-of-the-box equivalent. What is your main goal? What are you trying to accomplish?

Thanks

Hi Ki,

 Sorry for the insufficient information

I am seeking to establish a MODBUS TCP communication with launchxl2-570lc43 and venus gx. The venus gx acts as like a mediator in between TI board and other devices connected to it.

My aim is to receive the information gathered in the venus gx to the TI board through an ethernet cable. I have tried lwip demo, but that wasn't sufficient to get the data from the venus gx. 

So I moved to socket programming. This is only my guess. I have very limited knowledge to know whether this is right or wrong step. I need assistance. Pls help.

Hello QJ,

I have tried the LWIP example & the Linking is done. But after that it shows " --- ERROR INITIALIZING HARDWARE --- ". 

I believe that this message is displayed when the IF statement is detecting ip address as 0. 

Is there a way to rectify this?

Hello,

The IP address can be set either as a static address, or as a dynamic address assigned by a DHCP server. The selection of the IP address’s configuration mode is done in the lwipopts.h file:

● Set #define LWIP_DHCP to 1 to configure the IP address by DHCP

● Set #define LWIP_DHCP to 0 to use the static address

Note that if you choose to configure the IP address by DHCP and the application does not find a DHCP server on the network to which it is already connected, the IP address is then automatically set to the static address (0.0.0.0).

Helo QJ,

I have made some changes as you said. The changes are listed below :

1. #define LWIP_DHCP to 0 and loaded it, the output was the same (" --- Error Initializing Hardware --- " )

2. To ensure that the detected ip address is 0, I made some in the if - else statement in the   lwip_functions.c 

The corresponding output was DBUG - Getting PHY ID....SUCCESS 

                                            DBUG - Getting PHY Alive Status ID....SUCCESS 

                                            DBUG - Getting PHY Link Status ID....SUCCESS

                                            DBUG - Setting up Link....SUCCESS

                                            Device IP Address: 0.0.0.0

I think the Venus GX id is not giving access to the TI board to have the ip address. I came to this conclusion because even if I connect the Venus GX as well as Launchxl2-570LC43 to PC ( one at a time ), the status will be " Unknown Device Connected ". 

Pls suggest solutions for this problem. 

Many Thanks and Magizhchi,

Padayappa
