we are using dp83640 connected whit arm3357. linux 3.2 run on the board. I edit the /net/phy/dp83640.c by adding printk in each function. but after I use testptp.c
in \Documentation\ptp\ and run it. the ptp devices can be found and I can run testptp. But there is no output information in dp83640.c.
the printk consol level has been edit to 7 so the screen can capture any information of printk.
