Subject: [U-Boot] [PATCH v2 0/2] x530: Enable watchdog
Date: Sat, 16 Feb 2019 09:51:29 +1300 [thread overview]
Message-ID: <20190215205131.22443-1-judge.packham@gmail.com> (raw)
We've seen some issues with the x530 under extreme conditions where the
DDR gets into a bad state. Generally this results in an application
crash followed by a lock-up in u-boot.
Enabling the watchdog prevents the lock up and will let the DDR training
have another go. Sometimes this recovers but even a reboot loop is
better than a complete lockup.
Changes in v2:
- update commit message
