I used the SDCardSaveJPEGTimelapse example program, but the images saved to the SD card are all 0KB.
It seems that Camera.getImage(CHANNEL, &img_addr, &img_len); cannot read the photos there.
I’m certain the CAMERA is functioning properly because it can perform object detection.
can’t find the reason at all…
Hi @Clay, i had tried on my side it seems to be working fine, however If the picture files shows 0kb then the pictures might have not properly moved/copied to the sd card. You may check on your sd card whether is working or remove and reinsert to AMB pro2. Thanks.
thank you for your reply.
The SD card is working fine, and I have monitored that img_len is always equal to 0, which is why I suspect there is an issue with Camera.getImage.

Hi @Clay,
Can I check what SDK version are you using? Also what are your options that you set on the Arduino IDE when you compile and upload the example? For example, camera option and is fast camera start enabled?
Thank you.
Thanks for your reply
I am using Arduino 2.3.3
board manager 4.0.8
and
setup is as follows:
I just compiled it again, and it seems to work now.
Reinstalling the board manager 4.0.8 fixed the issue.
Thank you all! @Kelvin_Huang @KaiFai_Y
