Part Number: BEAGLEBK

Hello,

For Beagle Bone Black, when I try to include the the watch dog timer feature in SPL through u-boot menuconfig

"Device Driver>Watch Dog Timer Support>Enable Driver Model for Watchdog timer driver in SPL"

The below build error is generated.

-----------------------------------

arch/arm/mach-omap2/built-in.o: In function `spl_board_init':
/home/workpc/uboot/code/u-boot-2020.04-rc2/build-am335x_evm/../arch/arm/mach-omap2/boot-common.c:211: undefined reference to `hw_watchdog_init'
make[2]: *** [spl/u-boot-spl] Error 1
make[1]: *** [spl/u-boot-spl] Error 2
make: *** [sub-make] Error 2

-----------------------------------

Does u-boot SPL for Beaglebone Black support Watch Dog Timer or not??

Regards,

Adarsh

Hello,

U-Boot Version:2020.04-rc2

Target Board:Beaglebone Black RevC

In the u-boot code for Beaglebone Black ,could you please elaborate on the menu-config option "Disable reset Watchdog" at

---------------------------------------------------------

Device Drivers> Watchdog Timer Support

----------------------------------------------------------

From the help given with this option,

" Disable reset watchdog, which can let WATCHDOG_RESET invalid, so that the watchdog will not be fed in u-boot."

I could not understand its purpose.

Was also trying to see if the other option "Enable U-boot Watchdog reset" along the same menuconfig path ,has anything to do with this?

Regards,

Adarsh

Adarsh,

I just tried the current upstream U-Boot and can confirm watchdog functionality already works in SPL with no further doing required on your end. When I update the code as follows...

diff --git a/common/spl/spl.c b/common/spl/spl.c
index 932e6ab98a..b82de9c14c 100644
--- a/common/spl/spl.c
+++ b/common/spl/spl.c
@@ -675,6 +675,11 @@ void board_init_r(gd_t *dummy1, ulong dummy2)
 
        bootcount_inc();
 
+       printf("%s: Entering forever loop to allow WDT to trigger in SPL...\n",
+              __func__);
+       volatile int halt_flag = 1;
+       while (halt_flag);

        memset(&spl_image, '\0', sizeof(spl_image));
 #ifdef CONFIG_SYS_SPL_ARGS_ADDR
        spl_image.arg = (void *)CONFIG_SYS_SPL_ARGS_ADDR;

...and build using the am335x_evm_defconfig and then boot/run U-Boot on a BeagleBone Black without any further changes I get this result of the device resetting itself every minute...

There are some particularities about the current state of upstream U-Boot that you should be aware of however:

In general various U-Boot drivers are being migrated to "Driver Model" (DM), which usually implies that device tree (DTS) is used for configuration/setup purposes
The SPL build based on the am335x_evm_defconfig currently does not use DTS for space reasons (to keep SPL small and to be able to support many board variants/features), however there are some non-TI AM335x defconfigs that do
Hence CONFIG_SPL_WDT (DM-based Watchog support in SPL) is currently not applicable to am335x_evm_defconfig-based builds
am335x_evm_defconfig-based builds instead use non-DM watchdog code for SPL, and use DM/DT based watchdog code only for U-Boot (proper)
If you look at the driver code located at drivers/watchdog/omap_wdt.c you see that there is essentially two sets of functions in there, whether CONFIG_WDT/CONFIG_SPL_WDT is enabled or not

See if you can re-create what I demonstrated and let me know in case there are any further concerns with this functionality.
