Hi all. I have a question on using TSEC Ethernet on a board with a MPC8541. I don't use CPM2 and FCC. I use only one TSEC for management. Since I only enable one TSEC, I #undef-ed the CONFIG_NET_MULTI flag. But then I couldn't use all the functions under eth.c, since its all under #if (CONFIG_COMMANDS & CFG_CMD_NET) && defined(CONFIG_NET_MULTI). What is the justification for CONFIG_NET_MULTI there? Should I just remove it, or I am supposed to have some other replacement for the Ethernet access that I miss?
Thanks a lot.
You're right - the TSEC driver won't work without enabling CONFIG_NET_MULTI. The purpose of this configuration option is to automatically cycle through the available Ethernet devices when attempting a network connection, moving on when a device's link is down. I imagine the person who wrote the tsec didn't imagine the case where someone would only want to use one device.
I intend to clean up the eth.c file some time soon because as you can see it's a big mess of #ifdefs.
Enabling CONFIG_NET_MULTI shouldn't cause you any problems. Just go ahead and do that, but only define the appropriate CONFIG_MPC85XX_TSEC? flags.
If this isn't clear, just let me know.
