Hi,
I am new to Indi and am running it on an OdroidXU4 (ARM based, running Ubuntu 18.04.2 LTS armv7l -32-bit). I just cannot get the QHY5 (old one abd pre-dates QHY5II).

When i run dmesg i get

Can anyone help?

I have the same problem too
www.indilib.org/forum/ccds-dslrs/4975-qh...r-working.html#37448
no idea what happened, it worked fine (for an old QHY5...) before.

I just emailed QHY to look into this.

Hi,
Having read many posts and tried many things the one that worked was to make a change to the udev rules files. On my system the files are

/lib/udev/rules.d/85-qhyccd.rules

/etc/udev/rules.d/85-qhy.rules

Look for the line below and make sure you have the QHY5LOADER.HEX bit on the end.

ATTRS{idVendor}=="1618", ATTRS{idProduct}=="0901", RUN+="/sbin/fxload -t fx2 -I /lib/firmware/qhy/QHY5.HEX -D $env{DEVNAME} -s /lib/firmware/qhy/QHY5LOADER.HEX"

This worked for me.

That udev rule fixed it, I used the one I had in my backup folder and copied it to /etc/udev/rules.d
and issued the following command:
# udevadm control --reload-rules && udevadm trigger
