I'm at the moment of using libiio for a Zedboard project that uses AD4020. I'm using 2019_R2 meta-adi now, just to be on the safe side based on my previous questions on 2020.1. I did my research on some questions here in the forum and in libiio wiki articles. I have some questions though.
1. How do I update the libiio version in my 2019_R2 meta-adi Zedboard setup? Right now it's v0.21, but I would like to upgrade it to v0.23 (which is the latest). The reason is that v0.21 does not include serial as one of its supported backends (based on iio_info) while v0.23 supports it. Is there have to be changes in the meta-adi recipes for this? I've already checked this link (https://wiki.analog.com/resources/tools-software/linux-software/embedded_arm_images) and I'm not sure if those SD images are applicable to my ad4020 zedboard application.
2. How to set up and start the serial backend in v0.23 libiio? I also need to connect to the serial UART (uart0 preferably since uart1 is the console). I'm not sure if I missed anything about serial backend setup in your libiio wiki pages, if I did so please point it out.
