<p><b>New page</b></p><div>I have an issue with the RTC clock and can’t find a solution.<br />
I tried to install a brand new OS from the official Raspbian Buster Lite, and did a clean install of the x728.sh script from github.<br />
The error code at startup of raspberry is:<br />
<br />
[ 22.027235] rc.local[621]: hwckock: ioctl(RTC_RD_TIME) to /dev/rtc0 to read the time failed: Invalid argument<br />
[FAILED] Failed to start /etc/rc.local Compatibility<br />
See ‘systemctl status rc-local.service’ for details.<br />
<br />
I think the problem goes around “hwclock”. <br />
Even if I try to “hwclock -r” the result is:<br />
hwckock: ioctl(RTC_RD_TIME) to /dev/rtc0 to read the time failed: Invalid argument<br />
<br />
How can i solve it?<!-- migrated from Comments; original IP: 87.19.206.239 --></div>87.19.206.239
