I Am trying to get the Watchdog to generate a warm reset on my HPS Baremetal Application.
My Setup:
Cyclone V custom board
Boot setup; BootRom -> Preloader -> HPS baremetal
Preloader and HPS loaded from QSPI Flash
Preloader in On Chip RAM and HPS in SDRAM
I use the following code to trigger the warm reset from the watchdog:
ALT_STATUS_CODE status = ALT_E_SUCCESS;
//status |= alt_wdog_int_clear(ALT_WDOG0);
//set to 90 second watchdog timer
if (status == ALT_E_SUCCESS) {status = alt_wdog_counter_set(ALT_WDOG1, 0);
if (status == ALT_E_SUCCESS) {status = alt_wdog_response_mode_set(ALT_WDOG1, ALT_WDOG_WARM_RESET ); }
if (status == ALT_E_SUCCESS) {status = alt_wdog_start(ALT_WDOG1); }
I can see the watchdog count down, then the HPS goes into Hung/Reset state, but does not recover or boot again.
Does anyone know what I am doing wrong. Should the warm reset not trigger the HPS to reload from the application Entry point?

Hi,
May I know the Quartus version that you are using?
How did you compile the preloader? Is it using the bsp-editor?
Regarding the reset issue, could you check below documentation since you are using Cyclone V SoC and QSPI to boot if the issue that you are seeing related, and that you may try the solutions mentioned:

Good day EBERLAZARE_I_In
Thank you for your quick response. I went through the document you provided and was able to resolve my issue. The QSPI needs to be reset before the watchdog triggers - else the HPS cannot boot.
Thank you
