U-BOOT:
I want to modify the default environment variable in U-BOOT. The following info are about the hardware:
ARM: at91rm9200
platform: at91rm9200dk
U-BOOT: CFG_ENV_IS_IN_DATAFLASH
I modifed /include/configs/at91rm9200dk.h and add the following lines after "#define CONFIG_BAUDRATE 115200":
#define CONFIG_ETHADDR 12.24.96.78.91.11
#define CONFIG_IPADDR 172.19.71.10
#define CONFIG_SERVERIP 172.19.71.40
#define CONFIG_BOOTCMD = tftp 20008000 zImage; tftp 21000000 Ramdisk.gz; go 20008000
the first three commands work well, but the last command is not in the environment. I use printenv command to show the current
environment:
U-Boot> printenv
bootdelay=3
baudrate=115200
ethaddr=12.24.96.78.91.11
ipaddr=172.19.71.10
serverip=172.19.71.40
stdin=serial
stdout=serial
stderr=serial
There is not bootcmd command. How can I implement this function? ( just add bootcmd before compile u-boot)
best regards
