I'm trying in board iMX233-OLinuXino-MICRO ( https://www.olimex.com/Products/OLinuXino/iMX233/iMX233-OLinuXino-MICRO/open... ) setup hardware watchdog in the uboot.
I checkout uboot code and recompile it(I found steps here : http://www.jann.cc/2013/02/07/u_boot_for_the_imx233_olinuxino.html).
I tried to call a function hw_watchdog_init from class: imx_watchdog.c ( http://git.denx.de/?p=u-boot.git;a=blob;f=drivers/watchdog/imx_watchdog.c;h=... ) in the code .
In this method, I uncomment line # define CONFIG_WATCHDOG_TIMEOUT_MSECS 128000 and I expected that the system will be restarted after, 128 seconds, but did not. I am sure that this method(hw_watchdog_init) is called because before and after i write debug messages to console
I tested like this:
1. recompile code with calling method hw_watchdog_init 3. upload this file to my SD card with dd command 3. start linux 4. waiting for 128 seconds and I was expecting that the system will berestart but did not.
What to do?
WDOG1_BASE_ADDR -> what is the value of this variable ?
Thank you
