ATECC108 Chip stopped working after personalizing chip

[mutexlocker]

Hello,
I have successfully compiled EClet on my raspberry pi .
I have soldered ATECC108 to my own PCB and i don’t use any development board, after connecting i2c pins and 3.3v and GND to chip i was able to find the chip at address 60 using i2cdetect -y 1,then i ran sudo ./eclet state and got "Factory" as response. But after that all commands got stuck in terminal and nothing happens sudo ./eclet personalize and sudo ./eclet random returns nothing and also i2cdetect -y 1 command is not finding the chip anymore.I think its burned i have more chips i can test but i just want to know your opinion why the chip is not recognized anymore after running state command.
I can see in your PCB you have used 1uf cap between GND and Vcc do you think it has something to do with that ?

I've used it w/o the bypass cap before. It's good practice, but unless you have some really dirty power, you should be fine.

Try running it with the --verbose or -v flag--it should give you more details about what's going on at the i2c level.
