Print Page - unexpected bootloader mode

Title: unexpected bootloader mode
Post by: ricar on August 01, 2016, 01:07:39 PM

Hi,
I have a problem with A20 Olinuxino LIME board.
The device I have been using is A20-Olinuxino LIME board, with Debian GNU/Linux 7.6 (wheezy) image booted from NAND.
After a reboot the device automatically entered in bootloader mode (#sun7i). This behavior is unexpected. There is a method to automtically boot the device when it enter in this mode?

Thanks

Which bootloader is it in?

In case uboot, RTFM or try h :)

In certain scenarios, when serial console or usb hid devices are attached and key pressed is detected or "detected", booting can break into u-boot prompt.

Is this the case?

What do you mean for detected or "detected"? In my case serial usb cable is attached but I haven't pressed any key.

I have seen a bad serial cables (bad ground?) that were breaking u-boot without any key pressed. Just try without.
