Subject: reset / watchdog on an imx7d soc
Date: Tue, 23 Jun 2020 15:45:38 +0200 (CEST) [thread overview]
Message-ID: <925732743.424285.1592919941556@mail.vodafone.de> (raw)
Hi,
I'm having problems with the reset command on an imx7d soc.
As far as I understand it, to reboot barebox on an imx7 the 'reset' command
invokes the watchdog1, forcing it to do its job:
in drivers/watchdog/imxwd.c:
static void imx21_soc_reset(struct imx_wd *priv)
...
val |= IMX21_WDOG_WCR_WDA; /* do not assert ext-reset */
imxwd_write(priv, IMX21_WDOG_WCR, val);
...
What I see is that shortly after the imxwd_write() call the soc hangs but it
doesn't reboot.
Can anyone confirm that the current barebox is able to restart an imx7 soc without
using external signals ?
Do I need to enable / configure some other soc controller ?
Currently I just enable the wdog1 in my device tree:
...
&wdog1 {
status = "okay";
};
...
giorgio
