Lwip Ppp Over Serial Port

Broadcom Driver Windows 10 Netxtreme 57xx. Raw Message Hi guys, I'm really sorry but after 10 days spent with lwip stack, it's time to ask help. I'm working with a custom board based on stm32f103 and on ublox Leon-G100. My first attempt was to connect the board trough the serial with pc and use pppd to connect.

The test was successfully passed, I got with a speed test (console version) 8-14KBytes/s. The firmware was a simple pass-trough between two uarts.

Pcboardgprs After that I started to work with lwip to test with a small stack directly on board. I read that article and honestly after 5-6 hours of work I got the first result, the board was successfully connected to the apn, I got the ip,gateway and mask but after that, no more progress come:P Basically I initialize the modem and put it in data mode, then I call pd = pppOverSerialOpen(PPP_SERIAL_PORT, linkStatusCB, &connected); to link up the connection and it goes well. Attached the log, I apologize if it is rude.

If you need to change the debug mask let me know. The garbaged log probably means you are violating lwIP threading constraints.

I want to connect com1 to the SAM7X serial port. I also did a port of lwIP + ppp for FreeRTOS on a. In addition I improved the lwIP/FreeRTOS port and fixed.

You can notice that PPP negotiated up to a running session in your log, which is quite a good news. The pppos_input() function in lwIP 1.4.x is not thread safe, maybe that's the issue. You could try setting PPP_INPROC_MULTITHREADED but the name is misleading, that's only IRQ safe (i.e. Safe with one way preemption and different priority) but not thread safe. Or better, you could try lwIP 2.0.0 Beta1, where the PPP stack was fully reworked if not totally rewritten.
