Write u-boot binary from RAM to FLASH memory. bootm - boot application image from memory go - start application at address addr loop - infinite loop on address range exit - exit script Download commands. Download u-boot binary into Habanero's RAM. The Linux kernel is booted and configured to use NFS as the root file system resident on the NFS server. The FPGA configuration file, device tree, and kernel image are downloaded from the server using TFTP in u-boot. Reboot Habanero and press ESC when prompted to enter bootloader then press a few times to clear console buffer.Ħ. U-boot is loaded on the target hardware (SoCKit in this example). Set 192.168.1.254 IP address on your tftp server's ethernet interface.Ĥ. Binary file name can be different as shown in video.ģ. The Linux kernel, device tree, and potentially the FPGA configuration file are all loaded from the server using TFTP. This process uses bootloader software such and U-Boot and a Linux host setup to act as the TFTP and NFS server. Copy u-boot binary to the tftp directory. If there is an Ethernet interface available, this can be done by booting over network using TFTP and NFS. Keep in mind that warranty does not cover Jalapeno module if it is damaged due to user's fault.Ģ. The tftp U-Boot command is used to transfer files to the system. The entire process can be run using u-boot command line or scripts. U-Boot Explained This section will explain how the process works and what is the theory applied behind this procedure. U-boot is loaded on the target hardware (SoCKit in this example). DHCP Server: To assign an IP address to the codec so that it can communicate on LAN. Starting from BSP 5.1.0 U-Boot leverages Distroboot capabilities for network boot. ATTENTION! Bootloader upgrade is a risky operation and should not be performed unless absolutely necessary! If anything goes wrongĭuring this process (power shortage, mistype, etc.) the board will be BRICKED (broken). TFTP Server: To store the package file from which the codec can download the file.
