Petalinux in Cora z7 not finding RTC

Question

Hello everyone!

I'm trying to install Petalinux on a Cora Z7-10 I followed all the steps described here: github.com/Digilent/Petalinux-Cora-Z7-10 but when I try to boot it I get this message:

hwclock: can't open '/dev/misc/rtc': no such file or directory

after this, I can't write anything in Minicom.

As in my folder /dev didn't have the misc folder, following some advice that I found on the net I created the folder and first tried to soft-link /dev/rtc0 and then hard-link it also but none of those worked, I still get the same error.

Did anyone go through the same issue or has any idea to solve it?

Thanks you very much in advance.

Hello @gmodia

Please try picocom: $ sudo picocom -b 115200 /dev/ttyUSB1

Note: this will work only after the device is powered on and the device /dev/ttyUSB1 is provided by your machine kernel. You could watch when that happens in a second terminal window by issuing: dmesg -w

Hi @gmodia,

Welcome to the digilent forums!

I moved your thread to a sub-section where more experienced embedded linux engineers look.

best regards,

Jon
