RamDisk and wifi network driver
Hello.
So I have wifi working on my board TI AM335x with the TI/QNX driver. I have followed all instructions and it is all
working.
The thing I'm doing (and I think this is wrong) is that I startup the "io-pkt-v4-hc -dasix" running and then I start
some of my applications. These applications setup listening ports on the loopback device.
When I startup the ramdisk and then startup the new io-pkt-v4-hc -dti127x-am335x driver my loopback interface is created
new.
netstat shows me none of my listening ports on the loopback interface.
I'm not sure what the pros/cons are of starting up all my apps in a ramdisk. My understanding of a ramdisk is a bit
shaky. I've read all the docs I can find on it. My understanding is that the ramdisk is only affecting the file system
and not the amount of system ram I have available for running my applications. Obviously the ram used for the ramdisk
is consummed but the rest of it should be there.
Is this correct?
Needless to say, I would think that the loopback device would stay consistent throughout the system. But I'm finding
that not to be true.
When I start up an application in the ramdisk world, I can't connect to the apps that were started before I created the
ramdisk.
Can anyone point me to docs that describe how this works? The devb-ram driver doc doesn't seem to touch on networking
and drivers that are loaded in the existing system. Or maybe I just missed it.
Thanks in advance.
