ASI 178MM Inconsistent image btw ARM driver and INTEL driver

patrick-81

Hello all,

I come back with my problem of different image width between a driver made to work on ARM device running LINUX and an INTEL device running also LINUX.

I don't understand why not to exploit all the sensor on ARM device (this is new ??) and why INTEL drivers are not aligned on ARM ones. This might involve errors and introduce a lot more work to do to rebuild all pre-processing reference images libraries even maintain 2 different libraries.

Will you converge to a unique format ?

I hope.

With open source code user could compile the code to given arch. With closed source it's up to the vendor to build and maintain all of the archs that users may need. ARM is less popular so it's not surprising it gets less attention.

sorry, can you tell us detail about your problem？

@riklaunim

As it is not possible to have the hand on the SDK it is not possible to compile the code to align ARM device with INTEL devices.

And I am not sure that it is a less attention to those devices. I hope this is a much more unfortunate choice. I hope it will be fixed some day. Meanwhile I will try to be aware and use bypasses.

Hello Sam,

My problem is the following one:

The sensor on the 178MM is a 3096x2080 pixels size.

With the linux drivers used with INDI/EKOS/KSTARS on INTEL platform the displayed resolution is the right one 3096x2080.

With the drivers for ARM device (ODROID-XU4) the displayed resolution is 3072x2080. If I try to push the width to 3096, I can't. A message is diplayed telling that 3072 is the max value (like this value is hard coded).

The result is that the previous work done on INTEL device (darks, flats, etc..) are not consistent with the picture taken in remote with the 178MM connected to a ARM device. The following result is that pre-processing crashes when trying to use pictures with different resolutions.

Hi, please try this version, I think this issue have been fixed.

Hello Yang,

Can you tell me how to use this file ?

Have I to recompile all indi lib and driver ?

Thank you

Best regards

Hello Yang,

I have copied library and headers to the folder used by indi, adding the filterwheel static library.

I re-compiled the driver. And... all works fine. The image is full frame @ 3096x2080 taken from the remote ARM device.

Hope you will transfer quickly the mod to Jasem for an integration in indi.

Thank you for the help.

Best regards.
