Can't find IP address

[Purecade]

I tried to modify the static IP address of the Raspberry Pi. After the modification, I can still use it and find the IP address. However, after a week, I can no longer find the IP address and cannot log in with SSH. My two The modules are all like this: RevPi Core3 and RevPi Connect+, is there a way to solve them.

Steps to modify static IP address：
1、Input command：sudo nano /etc/dhcpcd.conf

2、Add content in dhcpcd.conf：
interface eth0
static ip_address=192.168.1.100/24
static routers=192.168.1.1
static domain_name_servers=192.168.1.1

Hello with interest I read your description of the problem.
I can understand the steps you have taken.
Probably you just forgot one letter
Shouldn't it say "interface eth0"?

Hello，This may be accidentally deleted when I took the screenshot, but I can be sure that I wrote "interface eth0"

Hello，
I know that resetting the system can solve the problem, but my project must have a static IP address. The same setting still causes me to find the IP address. I have tried to reset the system, but if I set a static IP address, I still cannot find the IP address.Do you know any other way, thanks you.

Hi Purecade,

which image version do you run (cat /etc/revpi/image-release)? Is there any error message in the logs after the connection is lost (reboot and check with jourctl -u dhcpcd)?

Hi Nicolai,
I run buster imager.I want to connect my RevPi Core 3,but I can't do SSH login.And my Mirco USB port is broken and I cannot reset the system.For my RecvPi Connect, I fixed the Ethernet port A, but I can't find the IP address for both interfaces. I am very troubled.

Hu Purecase,

so you basicaly have two problems:

I want to connect my RevPi Core 3,but I can't do SSH login.And my Mirco USB port is broken and I cannot reset the system

Does the local login via an attached HDMI monitor work?

For my RecvPi Connect, I fixed the Ethernet port A, but I can't find the IP address for both interfaces. I am very troubled.

What do you mean with "fixed the Ethernet port"? What did you try to configure the ip addresses (please share complete configuration file)?

Yeah,I try it.But I can’t enter the desktop, and I get stuck in the process of entering.It shows:[Failed]Failed to start File system Check on Root Device.

Sorry,Maybe my expression is inaccurate.I mean to set a static IP address.
