Raspberry Pi 3 - Segmentation fault wih ASI20

microastro

Hi,

Need some help guys.

System info:

-Raspberry Pi 3

-Raspbian GNU/Linux 8 (Jessie) - 2016-09-23

-SDK ASI_linux_mac_SDK_V0.4.0929 and ASI_linux_mac_SDK_V0.3.0727

-ASI20MC

Problem:

-Starting an exposure with ASIStartExposure some times aborts the program with the "Segmentation fault" error or ASIGetExpStatus just keeps returning ASI_EXP_WORKING and them the program hangs, ASIGetDataAfterExp never even gets called.

Consideration:

-With either SDK (4.0929 and 3.0727) the camera is recognized, I can open the camera, list its attributes, set its properties.

- I have taken in consideration the need to call ASIInitCamera depending on the SDK version.

- I have tried with other programs (oaCapture, Lin-guider, ASI demos, etc) and the result is the same "Segmentation fault" error or the program just hangs after an exposure/capture is initiated.

- I have used every version of libASICamera2.so that is available.

- I have set max_usb_current=1 in /boot/config.txt to allow more Amps on the USB ports

So, what the heck i'm doing wrong ? Any other reports of the same problem on the Pi 3 ?

Best regards,

Well ... someone at ZWO should read the USB specifications !!

BULK TRANSFERS:

- 512 bytes for high-speed endpoints

- 8, 16, 32, or 64 bytes for full-speed endpoints

- low-speed bulk endpoints are not allowed at all

Thanks for wasting my time troubleshooting YOUR MISTAKES ! : :

some device is very strictly on the 512 byte but some does

you can use our upgrade tool to flash the compatible firmware

then the endpoint will be 512 bytes

PS: it's a very good project!
