Hi out there!
I've managed to build a quite complex system based on Tinker, using
1 Wire sensor, I2C-s, all of all UART's, and all of all remaining GPIO's... :-)
Unfortunately a long term test in a climate chamber have failed...
(although the core was just heated up to 70 degrees Celsius)
The need for a hardware watchdog then arise...
I've build new kernel using latest compile.sh with the HW watchdog checked resulting
Linux tinkerboard 4.4.110-rockchip #2 SMP Wed Jan 10 16:41:03 CET 2018 armv7l GNU/Linux
but there is no
/dev/watchdog
Not even in /proc/iomem at ff800000...
(it seems okay in dtb, as well as in /sys/devices/platform)
Now what?
Any help would be kindly appreciated,
SG
