<p><b>New page</b></p><div>I seem to be getting errors in "PiKVM - RTC-based hardware watchdog"<br />
The error: "Permission denied: '/sys/class/rtc/rtc0/wakealarm'"<br />
<br />
And sure enough, that path does not exist in "/sys/class/rtc/rtc0"<br />
<br />
I tried changing the line in /boot/config.txt to:<br />
"dtoverlay=i2c-rtc,ds1307,wakeup-source"<br />
<br />
However that did not resolve the error for me.<br />
<br />
I saw another post mention this setting:<br />
"dtoverlay=i2c-rtc-gpio,ds3231,i2c_gpio_sda=17,i2c_gpio_scl=27,wakeup-source"<br />
<br />
I did not try it, since I'm not sure which pins the X630-A3 is connecting to the RPI4 GPIO for the RTC chip. (and messing with I2C blindly is a bad idea)<br />
<br />
Can you please let me know if there is a solution to setting/fixing up the alarm/wakeup feature of the DS1307?<!-- migrated from Comments; original IP: 94.252.62.6 --></div>94.252.62.6
