Watchdog Disable new SOC EDS Flow

[RobertGreen]

Hi,

We are upgrading our flow to the new Bootloader build instructions as given in  in https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10

With the previous flow, it was possible to disable the watchdog timer by Unchecking the option spl.boot.WATCHDOG_ENABLE when running the BSP-editor.

How is this done now in the new flow? We are not able to disable the HW_WATCHDOG when configuring U-boot before running the final make.

Any assistance would be appreciated.

Thanks

Hi Robert,

You can disable the watchdog from uboot using the new flow, the details in the github

https://github.com/altera-opensource/u-boot-socfpga

follow the build u-boot step in building bootloader

- Watchdog:

    CFG_SYS_WATCHDOG_FREQ

    Some platforms automatically call WATCHDOG_RESET()

    from the timer interrupt handler every

    CFG_SYS_WATCHDOG_FREQ interrupts. If not set by the

    board configuration file, a default of CONFIG_SYS_HZ/2

    (i.e. 500) is used. Setting CFG_SYS_WATCHDOG_FREQ

    to 0 disables calling WATCHDOG_RESET() from the timer

    interrupt.

You can use this step to disable the watchdog

Thank you,

Hi Aliff,

We decided to write to the CPU Watchdog reset registers in uboot to solve our issue, compiling with the CFG_SYS_WATCHDOG_FREQ set to 0 did not work as expected.

We can close this thread. Thank you for the assistance.
