Access Violation

[eltigre4jc]

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?

Hi,
If you copy-paste the exception + stack-trace that occurred, that'll show if the error happened on the client or server.

Right, this is TFTP error code 2, sent by the server. It means you don't have write permissions in the directory you're trying to upload to.
