Hi! just want to share the experience. I'm using Armbian in an environment that cannot access the internet. So, NTP becomes a big issue, and I have to setup my local NTP server using Chrony. Things should be simple, but it just didn't work out. I stuck with this problem for a few weeks until I realized I'm trying to setup Chrony NTP server on a virtual machine. Then, I found this one on stackoverflow. https://serverfault.com/questions/1062023/the-least-bad-settings-for-chrony-as-the-ntp-server-on-a-virtual-machine It suggests how to setup NTP server on virtual machine, but I didn't follow through as I solved my problem by setting up Chrony NTP server on a physical server instead. So, just want to share the experience in case anyone stuck with similar problems as mine.

I use NanoPi M1 (m1-map.properties). This MMIO property file is working with Orange Pi H3, but I think the pin arrangement on each SBC may differ. For example, the pin "203" is not present in OrangePi PC Plus.

Thanks for your answer. I just use GPIOD to do a simple test with Java UIO on Orange Pi PC Plus (both GPIOD and MMIO GPIO) and it is working well

Hi, First of all, I would like to say a big "Thank you!" for making this project. This project is very promising especially for its cross platform and performance. I'm trying to use Java UIO on Orange Pi PC Plus. Since this SBC is using the same CPU as NanoPi M1 (Allwinner H3). I think I could use NanoPi M1 "input file" to work with Orange Pi PC Plus. I could install and compile Java UIO on Orange Pi successfully. However, when I tried to run LedBlink demo, it didn't work out. So, I thought it didn't work because I use the wrong input file. So, I tried to read the code to find a way to specify the input file, but couldn't find any. So, I take a look at another source code (Gen.java) and see that it clearly has an argument to specify the input file. So, my question is very simple. How could I specify the input file in the demo program? Sorry if I'm asking a silly. I'm an experienced java programmer, but I'm quite new for low-level programming (e.g. GPIO) in java.
