aop — AOP coprocessor
Non-maskable interrupt raised by the Always-On Processor (the part of the SoC that is always powered). iFixit and REWA most often associate it with the power button flex or the front camera / sensors assembly.
iPhone
Power button flex or front camera assembly
Non-maskable interrupt raised by the Always-On Processor (the part of the SoC that is always powered). iFixit and REWA most often associate it with the power button flex or the front camera / sensors assembly.
First check
Boot with the front camera disconnected, then with a known-good power flex; inspect the connectors (corrosion).
On iPhone SE (2nd generation)
Ambient light sensor, rear microphone (noise cancellation), power flex (7 Plus) or Touch ID flex
Generic Always-On Processor panic. REWA cites the light sensor, the noise-cancelling microphone near the rear camera, the power flex (iPhone 7 Plus) and the fingerprint flex as suspects; read the rest of the message to narrow it down.
First check
Read the text following “AOP PANIC” (Bosch, No pulse…); failing that, test by disconnecting the listed flexes one by one.
iPhone
Sensor connected to the AOP coprocessor (part not determined)
Panic of the always-on coprocessor (AOP), which handles the sensors while the screen is off (motion, proximity, light, microphones). The message matches no documented variant: the exact part cannot be deduced from this log alone. The most cited causes are a connected sensor (proximity, Face ID, microphones), the Taptic Engine or, more rarely, the coprocessor itself (logic board, often after corrosion).
First check
Compare several logs: if the same text returns, note the word after “pulse” or “PANIC”.
