8.7.3.3 Linux Execution with U-Boot Autostarted on Power-On
ARC AXS103 boards have built-in SPI-flash storage that you can use to host auto-started
applications such as bootloaders.
The batch file
axs_comm_progam_uboot.bat
flashes
u-boot_axs103.bin
into SPI
flash. Before running
axs_comm_progam_uboot.bat
close any hyperterminals (such as
PuTTY) and debugger windows that are using the USB data port of the AXS Software
Development Platform.
