Booting Linux kernel from networkīecause u-boot can’t handle NFS (actually, u-boot can, but not really well supported), we need to use TFTP (Trivial File Transfer Protocol) for this. To achieve this goal, 2 different steps are needed “ booting Linux kernel from network”, and “ mounting root filesystem from network”. If SD card is broken, you just have to recover quite a few boot related files. But if, you configure u-boot once, the device can download all other things (hardware bitstream, device tree blob, kernel and rootfs) from network, it will save your work significantly. Step 3 needs “physical access” to the device, and this is really painful. Generate boot file, and put everything onto SD card.

Compile the kernel again with new device drivers.Change hardware design, and generate new hardware bitstream and dtb.If you are using this device, this might happen Zedboard has SoC (System on Chip), which has FPGA. This is really useful if you are using devices like Zedboard.

U-boot is capable of connecting to network, and be able to download various files from network. But true reason for that is, to boot other nodes from network.

We are using GNOME on Ubuntu in these steps. However, most or all systems have a disk management application similar to the one we are using below, so you should be able to follow along. These steps are going to vary depending on which distro and desktop environment you are using. Check the fdisk -l output to verify changes that you make. Repeat the steps as necessary if you need to toggle another disk partition’s bootable flag on or off.

Finally, issue the w command to write the changes you have just made.
