On the U-Boot command line, replacing appname by the name of theĪpplication, e.g. If you prefer a different location, add the following line to UserConf.mk in yourīINDIR = path/to/my/tftp/upload/directory This will copy the final binary to nut/bin/arm9. Packages are available for Linux, we recommendįor building your Nut/OS application, use This requires to install a TFTP server on your PC. Nut/OS applications for Ethernut 5 are typically compiled for running in SDRAM.ĭuring the development phase it is most convenient to load them over Ethernet, This chapter assumes, that you are familiar with building Nut/OS applications. When using TeraTerm, select Setup -> Serial Portįorm the main menu and specify a transmit delay of 100 ms per line. Either use a slower baudrate or add a line delay in your terminalĮmulator configuration. If copied in one go, this may fail, because the lines are sent too fast for Tftpboot $'Įcho Enter MAC address and then execute \'saveenv\' to store the new environment. You can also load the environment over TFTP: If not, refer to this page, whichĮxplains how to program your board with the Ethernut 5 flasher application. However, this requires, that an environment image is available in the In this case enter the following commands to apply the factory default: On virgin boards, the command setfactory will not be available. U-Boot no mtdparted from U-Boot> prompt 23:53 johns at 9:59. To permanently store the new environment, use All of help / color / mirror / Atom feed. Note, that your previous environment will return, when rebooting the board First, it sets the bootargs environment variable, which U-Boot passes to the kernel as its boot parameters, and then uses the bootm command to boot the kernel located at (kerneladdr). Alternatively you can use a locally assigned MAC address. In turn, this environment variable is a set of commands of its own. Each board manufacturedīy egnite do contain a label with this number. Where 00:06:98 is the organizational unique identifier (OUI) assigned to EthernutsĪnd XX:YY:ZZ is the unique part of the individual board. ![]() You should now enter the MAC address of your board in the format U-Boot will load the environment image into SDRAM and apply it:Įnter MAC address and then execute 'saveenv' to store the new environment. In addition to the environment variables saved by saveenv, the serial FlashĬontains a factory default environment at address offset 0x021000. Saves the current environment in serial Flash memory (DataFlash) at address offsetĠx3DE000, from where it is reloaded during the next system start. To create new environment variables or to modify existing ones, use Set the bootargs variable to tell the kernel to boot into the NFS filesystem: NOTE: On initial use of U-boot the console variable should be set to the devices debug UART and buad rate, so kernel boot information can be displayed to the console. U-Boot is customizable by environment variables, which may contain scripts that are ![]() As a result, the board will always use the fixed IP address. Local IP address, and, when saving this modified environment, the dhcp Once done, the variable ipaddr will then contain the U-Boot to query an IP configuration from the local DHCP server prior to executingĪny network command. ForĮxample, the variable ipaddr may be set to dhcp, which instructs Result in unexpected problems, when other commands had been executed before. The command saveenv will store the current environment. Before changing environment variables for saving in serial Flash, reboot theīoard first to make sure to start with a clean environment.
