I am trying to get network support working on the Embest imx6 Marsboard. I have been reading through the various imx6 boards and it appears that some at least store a MAC address in the fuse memory.
This does not appear to be set on the MarSboard - the fuse memory contains 0. The original 2009 version used the ethaddr environment variable. If I try to include this in the config header file either as part of the CONFIG_EXTRA_ENV_SETTINGS -
#define CONFIG_ETHADDR 00:01:02:03:04:05
#define CONFIG_EXTRA_ENV_SETTINGS \ "ethaddr="__stringify(CONFIG_ETHADDR)"\0" \
or more simply as in the original version
"ethaddr=00:01:02:03:04:05\0" \
everything compiles, but when booting I get "Warning: failed to set MAC address" and when listing the environment variables ethhaddr is missing. If I manually set ethaddr and ipaddr the networking seems to work as I can ping the board successfully.
I assume I am missing something somewhere and I expect if I go through the source I will eventually find it, but it is probably going to be quicker to ask.
many thanks Ben
