Enabling watchdog in A20 uboot


Recommended Posts

Hello All,

 

I have a requirement that we need to enable the watchdog in uboot and kernel.

 

For Kernel I was able to enable it using the config below and using a "watchdog" utility. 

CONFIG_WATCHDOG=y
CONFIG_WATCHDOG_CORE=y
# CONFIG_WATCHDOG_NOWAYOUT is not set

#
# Watchdog Device Drivers
#
# CONFIG_SOFT_WATCHDOG is not set
# CONFIG_GPIO_WATCHDOG is not set
# CONFIG_XILINX_WATCHDOG is not set
# CONFIG_CADENCE_WATCHDOG is not set
# CONFIG_DW_WATCHDOG is not set
CONFIG_SUNXI_WATCHDOG=y
# CONFIG_MAX63XX_WATCHDOG is not set
# CONFIG_BCM7038_WDT is not set
# CONFIG_MEN_A21_WDT is not set

Now i'm stuck how to implement it in uboot.

BTW, I'm using A20 board and a mainline uboot.

 

Hope anyone can help.

 

Thanks in advance.
