Raspberry Issue

I’ve tried to make the bootable SD, I’ve connected the arduino, turned the power on,
The red led stays stable and the green led flashing, in arduino the led stays blinking. But I coudn’t find the wifi farmbot-xxx, in one minute the system resets it selves.

Could anyone help

Did you follow the instructions here to put FarmBot OS onto the SD card?

Yes, now Tried another card and works great, the fist one was one 4gb normas and now i get one 8gb xd faster, I’ve made the same things.
I don’t know if it is because the size the model or the card ( old card) .
Thanks for the attention
