Hello, months ago I made a lcd cape for beglebone A3 and it was great and the bone was booting very fast.
Now i bought two new beaglebone and i see are revision A5, one works as expected but the other one when i put the sdcard (the new one or the old one from revision A3, it doesn’t matter) and power the bone it lits the ethernet orange light and it stays there one minute or so, then it starts to boot normally.
I suppose there must a defective in the boot pins or in the sd memory connector pins.
Anyone can send me some light?
Is this with or without your LCD board attached?

Thx for answering Gerald,
I have found the defect in the beaglebone, it was a bad 100k resistor in a sysboot line that was altering the boot mode, i soldered a new one from a burned beaglebone i had and everything is ok now.
It’s been a challenge, those resistors are really tiny and it was also hard to desolder that leadless tin.

Yep. They are small and lead free solder is a pain.
