This is not actually a bug report (and certainly not a crash error!). For questions like these, send a mail to the lwip-users list.

Hello everybody,

I use LWIP 2.1.2 on a STM32 and would like to use SLIP_RX_FROM_ISR. To do that I set SLIP_RX_FROM_ISR to 1 and SYS_LIGHTWEIGHT_PROT to 1. Now I can use slipif_received_byte() from my serial rx interrupt and slipif_process_rxqueue() in the main to get the data out of the buffer.

However, when I set SYS_LIGHTWEIGHT_PROT to 1 i get the error:

"identifier sys_prot_t is undefined", thus I have defined it with: typedef unsigned int sys_prot_t.

But now I get the error message:

"identifier old_level is undefined"

Did anybody had the same problem? Can anybody help? Any ideas?

I really appreciate any help.
