Hi,
I am transplanting pppd to C6A816x/AM389x DDR2 EVM board. But when I running pppd in the board ,pppd don't have garbled and stucking. I use two sdk(5.0.0.56 and 5.01.01.80), but still the same as the original.
When I used shell command (pppd call xxxx) to connect 3G, it would succeed to connect 3G, and ping g.cn was successful( ppp0 must is default route, if ppp0 wasn't default route, ping -I ppp0 g.cn would was unsuccessful).
After it had connected 3G,If ppp0 received or transmitted large data, kernel would receive or transmit data and application layer could not receive or transmit data(ex : ping could not receive or transmit data).
I had tried in other ARM board(ex: omap4430,S3C2440 etc).Other ARM board successful.
Regards,
