I'm also working on a cross platform desktop UI client, using Avalonia (tested on Win11 and Linux). It's in a separate repository located here: https://github.com/jpmikkers/Avalonia-TFTPClient

tftpclient's Issues

Access Violation

I have successfully used this client for transferring a bin file to a device.
But when I tried for another model, from the same vendor, I got Access Violation.

TFTPClient.Upload(New IPEndPoint(IPAddress.Parse("192.168.0.21"), 69), System.IO.Directory.GetCurrentDirectory() & "\" & path, "/tmp/temp/fw_1200.bin")

Why am I getting this error? it maybe something with the server?
