My customer found a problem in ping test. Does it look familiar to anyone?
Toolchain: bfin-uclinux-gcc - gcc version 4.3.5 (ADI-2012R2-RC2)
Kernel: Linux xj 3.5.7-ADI-2012R2 #16 Fri Dec 5 13:09:25 CST 2014 blackfin GNU/Linux
Using BF609 EZ-kit, boot into uClinux with IP address set to 192.168.31.168. The Ez-kit then pings to another machine with IP address (192.168.31.254) in LAN. There were 2 fails (ping not working) in 170 attempts.
This problem also happens on their customized board, DSP being BF607 and Ethernet PHY being Realtek RTL8201EL-VC-GR.
