BB-9 Camera can not turn on (無法攝像) (3/4) 1:無法進入拍攝模式,此為camera無法通過I2C信號被CPU正常識別造成,此不良主要查供電/reset/CLK/PWD是否正常 1. Camera shooting model is not accessible. The main cause is camera cannot be identified by CPU via I2C, need to check power supply for camera. 2:拍攝黑屏/油畫:此現象為手機進入拍攝模式后,但無法讀取景物,此類不良主要是camera無法通過DATA路徑將信號傳給CPU正常處理造成,此類不良主要檢查camera的DATA。 2. Photos are blurry/black when shooting, camera is not able to capture scenery after entering shooting model. The main cause is camera cannot pass signal to CPU to process via Data path. Need to check camera DATA path.
