Hello, it's me again. This time I'm getting stuck while flash pure for BBB, I write img from puredsd.ru to my sd card. But when inserting to BBB, hold S2 and the userLED0 only flash 2 times, there is no way to light up all 4 LED. So anyone know what I'm wrong?
Thank so much!
Thank so much!
I think the manual is a bit outdated. The new BBB boards automatically go to your SD card for startup when it is inserted. So do not push S2, it will affect the startup negatively.
Important thing is the BBB is connected to LAN. It has to see an active UTP connection.
Then when after powering up and 10sec blinking, ALL LEDs go out, the BBB is running pure. Maybe that startup from SD card take a bit longer, I do not remember, but it should never last longer than 30sec. The only blinking that remains is green and orange from the UTP connector.
Then you can acces the pure software with the http://pure.local and flash the SD card contents to eMMC using the system tab in the web browser menu from the pure software.
