Hi all,
I am struggingling the lwIP + PPP. My system OS is ucOS likes. My hardware
do not have LAN interface. PPP is use for GPRS module
1. For multi thread environement
u32_t sys_arch_protect()
void sys_arch_unprotect(u32_t pval)
Should the protect implement by the lock?
In the sys_arch.txt.
It said
* the API is used to disable task swtich
* the API could be implement by disable ISR.
I am a little confused about it. I study the code, and only find the code
is used for ++, --, so I think in multi task environeemnt, the lock
implement is enough. Am I right?
2. What is the suggestion task priority?
PPP task priority > TCP/IP task priorty.
My system preemptive system, so what is suggest task priorty?
