vCOM | N8VB vCOM Virtual Serial Port Driver creates pairs

I checked your code and tried in my ip camera. It is giving the same error. Then I just changed the reading line in loop with:

My coworker helped me figure out how to make it work! I think that the /= operator is created in the vnir scope, but not ported over to the entity I'm working on. By writing :use work.vnir."/="; at the beginning of the file it compiles, so the full entity looks like so:

Let's try to understand what the compiler is telling you here. At the end loop it was expecting an end if. That means that you are actually inside another if when you try to close your loop. The next error is just a consequence of the first.

Why is that so?

Let's check where the starts of the blocks in question could possibly be. At the end if above the end loop, you are obviously closing one if successfully, yet you are still inside another one, according to the compiler. You think you close the if(X(1)='1' and X(0)='0') then, but obviously you don't, otherwise we wouldn't have that error.

Is there another if between that one and the end if? Yes! It is in this line: else if(X(1)='0' and X(0)='1') then.

You obviously thought that this counts as part of the original if, but the compiler thinks otherwise, so that's the point where you would google else if vhdl. You would then find that the correct syntax is actually elsif, because otherwise you do else plus a new, separate if inside of the else, which is what happened here.

To visualize what happened, by using the indentation that would match what the compiler sees right now:

I figured out my problem. It has to do with the way I released the serial port. If you try to close a serial port when it doesn't exist anymore (ie, i already rebooted my device off of that VCOM), it'll throw an error. If you don't catch the error, it'll stick around in the registry until the program ends.

For posterity, here's what I did:

The problem was setting the external ip on my port forward to my public ip. What ip it was set to, it was only scanning for my ip, which let to only my computer being able to connect to it. I set the external ip to 0.0.0.0, making the port open to all ips.

You have two separate issues:

• DNS server configuration;
• NGINX web server configuration.

To solve issue with DNS you should follow one from two ways :

1. use Google Domains only:
   • configure necessary DNS records at Google Domains side by following documentation Resource records;
   • remove your zone from Google Cloud DNS.
2. switch to Google Cloud DNS:
   • create managed zone for your domain;
   • set custom DNS servers (same as NS records you can see at the previous step in created managed zone) for your domain.

After that you should wait for 24-48 hours for DNS propagation. You can check status of DNS online with services like dnsmap.io or mxtoolbox.com. If everything was configured correctly, you'll be able to see your application via http://domain.name and/or http://www.domain.name.

To solve issue with SSL you should follow instructions from these articles How To Secure a Containerized Node.js Application with Nginx, Let's Encrypt, and Docker Compose and Nginx and Let’s Encrypt with Docker in Less Than 5 Minutes to solve issue with SSL.

Because 'image can only be used on a scalar type, the compiler has no way of knowing that pkg_t can only be a scalar. Hence 'image cannot be used directly. Again with to_string, the compiler has no idea where to get it from, so cannot be used.

The only way to do this will be to pass in a to_string(p : pkg_t) function as a generic. If you add the <> value, the compiler will search for function signature that matches the function when the package is instantiated:

To pass multiple arguments contained in a single variable to a command, expand the variable using {*}:

You need to check if ExecuteScalar returns NULL.
