[U-Boot-Users] Watchdog timer reset

Hey folks,

Just wondering, does u-boot support periodical reset of watchdog timer ? If not, I suppose I have to disable the watchdog when I enter uboot in interactive mode, and probably enable it when I exit u-boot.

How does people normally do this ?

Just out of curiosity, (assuming u-boot does not do something like above), can we do something similar to below code?

-=-=-=-=-=-=-=-=-=-=-=-=-=-= signal(SIGALRM, runme);

function runme(void) { printf("hi\n"); alarm(10); } -=-=-=-=-=-=-=-=-=-=-=-=-=-=

Cheers,
