I need to enable the watchdog,but I don't confirm which timer is used for watchdog,

what is the base address to config the register?

how can I config watchdog timer?

when I write data to watchdog regiser with base address 0x4ae14000,

when call to

HW_WR_FIELD32(
baseAddr + WD_TIMER_WDSC,
WD_TIMER_WDSC_SOFTRESET,
WD_TIMER_WDSC_SOFTRESET_RESETCMD);

it is crashed.

in my application code,I have use a timer for interrupt.

my PDK version is pdk_am335x_1_0_13

Hi,

I suggest you study the Startware WD Timer example which I shared with you here: https://e2e.ti.com/support/processors/f/791/t/882097

Here is the output log of this example when executing on BBB:

StarterWare WDT CPU Reset Application!!
BOARDInit status [0x0]
SoC : [AM335X]
Core : [A8]
Board Detected : [BEAGLEBONEBLACK]
Base Board Revision : [UNKNOWN]
Daughter Card Revision: [UNKNOWN]

Total WDT instances present = 2
The instance address is 44e35000
Program Reset!Input ENTER key at least once in every 4 seconds to avoid a further reset.

The base address of WDT1 is also shown in the AM335x TRM (spruh73p.pdf), Table 2-2. L4_WKUP Peripheral Memory Map.

Frank
