Hello Gregory,
Thank you for your quick response.
Looking at the PRs, they seemed a bit complex for me :-| And I'm not
sure if it is that what I want or need.
What I was thinking was to use this call:
stm32_phyread(CONFIG_STM32F4_PHYADDR,MII_MSR,&phyval);
Then make the check:
if ((phyval & MII_MSR_LINKSTATUS) != 0) {
==> change the net driver flag that indicates if the network interface
is up or not;
}
Then in the application, I continue to check regularly the netlib_getifstatus().
Is there any way, or is it feasible, to have something like that? How
should I proceed?
Best regards,
Flavio
