You will need to add additional properties to the dts. Please find an
-example at, arch/nios2/dts/3c120_devboard.dts.
+example at, arch/nios2/dts/10m50_devboard.dts.
1. Add "stdout-path=..." property with your serial path to the chosen
node, like this,
chosen {
- stdout-path = &jtag_uart;
+ stdout-path = &uart_0;
};
2. If you use SPI/EPCS or I2C, you will need to add aliases to number
};
Next, you will need a default config file. You may start with
-nios2-generic_defconfig, modify the options and save it.
+10m50_defconfig, modify the options and save it.
-$ make nios2-generic_defconfig
+$ make 10m50_defconfig
$ make menuconfig
$ make savedefconfig
$ cp defconfig configs/mysystem_defconfig
binary. This is handy for development, eg, using gdb or nios2-download.
The last thing, legacy board header file describes those config options
-not covered in Kconfig yet. You may copy it from nios2-generic.h.

-$ cp include/configs/nios2-generic.h include/configs/mysystem.h
+$ cp include/configs/10m50_devboard.h include/configs/mysystem.h
Please change the SDRAM base and size to match your board. The base
should be cached virtual address, for Nios II with MMU it is 0xCxxx_xxxx
to 0xDxxx_xxxx.
-#define CONFIG_SYS_SDRAM_BASE 0xD0000000
+#define CONFIG_SYS_SDRAM_BASE 0xc8000000
#define CONFIG_SYS_SDRAM_SIZE 0x08000000
You will need to change the environment variables location and setting,
