Although the post was written for Ubuntu, the same idea can be applied to all systems. So, here is our problem. You set up a https://icesquare.com/wordpress/solvedtftp-error-code-2-access-violation/ TFTP server. It starts fine. You upload a file, it gives no error. Now, you try to download a file, it throws you an error: tftp> get myfile.jpg Error code 2: Access violation If you google the error message, Error code 2: Access violation on the web, you've probably noticed many solutions, some of them are very creative, such as running a touch command to create the file before downloading it etc. Before you try those solutions, ask yourself this question first: Do you want to touch 100 files before you download 100 files? Anyway. I am not sure what cause the TFTP gives the error message: Error code 2: Access violation. However I never experienced this error in my system before with my configurations and settings. Therefore, I am going to share you my configurations for your reference. My TFTP Configuration: service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = var/lib/tftpboot -s disable = no } There are couple things you need to pay attention. First, my TFTP root directory is /var/lib/tftpboot, and in my

I have not tried tftpput on u-boot. From the command help it appears address and size must be supplied by the command line. I would try that. I don't know where RAM is on your platform so I can't give a valid example command line but it should look something like: tftpput 80000000 10 ---- Old answer, may still be useful if the above does not help If it were me I would run wireshark on the tftp server to see what is happening. If you can't do that you can use a hub (not a switch) on the device and plug a pc into the same hub to run wireshark. (hubs are hard to find these days. If you don't have one from "the old days" this probably won't work for you.) You don't mention what tftp server you are running. Is it Linux based? The often used ones are dnsmasq and tftpd-hpa. I have used both with
pool of using diskless Ubuntu. Basically the client computer downloads the necessary files from the Ubuntu server every time during the boot. To keep things simple and easy, Ubuntu does that by using TFTP. So the first step is to set up a TFTP server on the server. For those who haven’t heard of TFTP, it is similar to FTP, except that it has no security feature, and the function is extremely limited. Anyway, here is how to set up a TFTP server on Ubuntu 11.10: Installing TFTP sounds easy. However, I’ve heard that many people experienced many issues during the installation, such as Error code 2: Access violation issue. That’s why I create this tutorial. If you follow exact the same steps, you will not experience any problem. First, let’s install all the necessary packages: sudo apt-get install xinetd tftpd tftp -y Next, we need to create a configuration file: sudo nano /etc/xinetd.d/tftp Put the following content into the file. service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = var/lib/tftpboot -s disable = no } In the server_args, I have var/lib/tftpboot, which represents the location of the tftp root, i.e., /var/lib/tftpboot. Notice that I skip the root /. Now let’s change the ownership of the directory: sudo mkdir /var/lib/tftpboot sudo chown -R nobody:nobody /var/lib/tftpboot sudo chmod -R 777 /var/lib/tftpboot and start the TFTP service: sudo service xinetd stop sudo service xinetd start Verify the TFTP is running correctly or not: netstat -na | grep LIST | grep 69 You should see something like this: tcp 0 0 0.0.0.0:69 0.0.0.0:* LISTEN Test: Upload a file to TFTP Server Now let’s test the TFTP server by logging into the server first: tftp localhost and upload a file: tftp> put myfile.jpg Sent 56733279 bytes in 5.7 seconds Quit: q Make sure that file has been uploaded: ls -l /var/lib/tftpboot Test: Download a file f
