Hi All, I'm trying to boot my C2 with a newly LE11 SD card. The boot works properly randomly. I've to insert the power supply more than 3/4 times before the system comes up. When the system does not boot the led stays red and to flashing blue light comes up, even in minutes. Every works properly when the system boots normally. The old LE9 boots properly every time. Any hint to solve this? Thanks in advance.

Share the UART output from the failed boots.

Thanks for your reply. Sorry for the stupid question but ... can you please suggest how can access the UART output? Is there a link with some instructions? Thanks for your help

You need to connect a USB > serial UART cable to the board. If you don't have one they are dirt cheap from Amazon.
https://wiki.odroid.com/odroid-c2/application_note/gpio/uart <= where to connect the cable board side. You also need a 'serial' app for your normal desktop/laptop computer OS .. there are lots of videos on YouTube for that.
The output will show whether the board boots at all, or boots and gets stuck somewhere.

Really thanks for your help. I'll get the cable and send the output as soon as possible. Thanks again for your help.
