Hello,
I have done search regarding the title however I could not find any information that answers my questions.
I am looking at enabling the Watchdog Timer for my Freescale iMX6 Solo (VAR-SOM-MX6). I have read the reference manual which outlines the following steps for Watchdog initialisation:
70.6 InitializationThe following sequence should be performed for WDOG initialization.
• PDE bit of Watchdog Miscellaneous Control Register (WDOG_WMCR) should be cleared to disable the power down counter.
• WT field of Watchdog Control Register (WDOG_WCR) should be programmed for sufficient timeout value.
• WDOG should be enabled by setting WDE bit of Watchdog Control Register (WDOG_WCR) so that the timeout counter loads the WT field value of Watchdog Control Register (WDOG_WCR) and starts counting.
From: http://www.nxp.com/assets/documents/data/en/reference-manuals/IMX6SDLRM.pdf
I noticed in the U-Boot files (/drivers/watchdog/imx_watchdog.c) there is no support for the Watchdog Miscellaneous Control Register (WDOG_WMCR) which is the first step of the sequence for initialising the Watchdog.
If there were any resources or guides upon this process that would be greatly appreciated.
Regards,
Brendan
