Hi Michal The *linux* cadence_wdt driver for the watchdog enables the clock that controls its behaviour. However this is not done in the U-boot driver; I dont think it is safe to assume that the clock will be active. do you know why is the driver making that assumption? and how to enable the clock?
Also, I am not sure it is either safe to assume that the WDT IP will be enabled; IMO during probe we should do something like this (otherwise the AXI bus will complain and fault the boot) static int cdns_wdt_probe(struct udevice *dev) { - debug("%s: Probing wdt%u\n", __func__, dev_seq(dev)); + u32 rst = 0; + + /* release WDT from reset */ + rst = readl(0xFD1A0100) & ~BIT(15); + writel(rst, 0xFD1A0100); + + debug("%s: Probing wdt%u)\n", __func__, dev_seq(dev)); return 0; } thanks Jorge
