ADI import error
KrishnaBalasubramanian opened this issue · comments
I have a raspberry pi (4B) with standard pi os. I trying to use it with CN0554.
I had recently installed libiio from source . Everything went fine:
$iio_info
iio_info version: 1.0 (git tag:27276d04)
Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64
installed pylibiio using pip (0.25)
installed pyadi-iio using pip. (0.0.16)
However, when I import adi, I get the following error:
/lib/arm-linux-gnueabihf/libiio.so.1: undefined symbol: iio_get_backends_count
I understand, from searches that the issue could be related to versions. Could you please advise how I should proceed ?
thanking you in advance
You need to install a released/tagged version of libiio. Latest is v0.25. libiio version 1.0 is from the main branch and is unstable.
Thank you so much for your swift response. That really worked.
However, still unable to get the CN0554 listed in the iio_info. Could you please correct my understanding as presented below:
- If I have Kuiper Linux, then most things are already set and pyadi should work.
- However, I have a standard RPi os. So, I need to build the ADI kernel according to https://wiki.analog.com/resources/tools-software/linux-build/generic/raspberrypi, before include dtoverlay in the config.txt.
I have some errors building the ADI kernel. And I know it will be huge learning for me as I havnt done anything like this before. So, I ask my question:
Do I really need to build the kernel and replace my kernel7I.img ? or can I just copy the .dtsi file into my /boot and just include the dtoverlay ?
Thanking you in advance.

Kuiper is outside the support for this forum. I would start https://wiki.analog.com/resources/eval/user-guides/circuits-from-the-lab/cn0554#software_setup . If you have further questions please post them here: https://ez.analog.com/reference-designs/
