on 2 occasions I saw people struggling with missing os_intr_lock and os_intr_unlock when migrating to
SDK 1.1.0. (May be interesting for @scargill, inspired by @tve)

In SDK 0.9.5 both were #defines to some ets functions which reside in rom:

Code: Select allinclude-sdk-0.9.5/osapi.h:#define os_intr_lock ets_intr_lock
include-sdk-0.9.5/osapi.h:#define os_intr_unlock ets_intr_unlock


Code: Select allld/eagle.rom.addr.v6.ld:PROVIDE ( ets_intr_lock = 0x40000f74 );
ld/eagle.rom.addr.v6.ld:PROVIDE ( ets_intr_unlock = 0x40000f80 );


So when code references os_intr_lock it really used ets_intr_lock.

In SDK 1.1.0 those defines where removed.

Add to that poor programming style using no prototypes that goes undetected and linker
tries to resolve a function called os_intr_lock which does not exist.

Solution:
Either add defines to your code or change code to use the ets_* functions directly.

And please encourage people to use prototypes!

Hope that helps,
Cal

And indeed, the lack of prototypes is horrible.

Wat does this function actually do?

Disable and enable all maskable interrupts (including debug interrupt) in the CPU respectively.
