[Buildroot] Build for Odroid-C2 not booting

[Gaha Bana]

hi ,
i installed fresh buildroot from git, and followed instructions to the
letter from
https://github.com/buildroot/buildroot/tree/master/board/hardkernel/odroidc2
Result burned to SD-Card and when i turn it on, nothing happens - bluelight
doesn't even blink just stays on meaning linux kernel hasn't really loaded
(stuck on u-boot?)
Could ANYone confirm it works for them ?

Notice that URL is not the official location of the Buildroot git tree,
just a mirror.

Do you get any serial output?

I don't have an odroid c2 myself, but very little has changed since the
config was added.

Dagg or Brian, can you confirm or help? Thanks.

hi Peter,
yes - it's just a link to 'instructions' ... here is what i did:


git clone git://git.buildroot.net/buildroot
cd buildroot

 make odroidc2_defconfig
 make menuconfig (leave with Esc-Esc and save the config)

 make


resulting sdcard.img found in output/images burnt to sd-card.


if anyone else can replicate it ... will take 15mins. at least i will
know problem must be in something else.


ps. i did try various SD cards , 2 different ways of writing to them
(linux and macos) etc etc to avoid usual suspects.

The default boot.ini shipped by Buildroot at
board/hardkernel/odroidc2/boot.ini contains:

# Default Console Device Setting
setenv condev "console=ttyS0,115200n8 console=tty0"   # on both

If you are monitoring the uart console only, can you try removing
console=tty0, leaving it only as:

# Default Console Device Setting
setenv condev "console=ttyS0,115200n8"

I have once noticed on my odroid-c2 that if I had this console "on
both", it didn't really work for the uart console.


Also, my odroid-c2 is unable to even load u-boot if I use old/slow SD
cards. I have to use the eMMC or a decently rated SD card for it to
work. The recommendation for Class 10 SD cards is something they even
mention in their wiki and product pages.

hi Erico,
not sure about boot.ini/UART thingy - i think C2 gets stuck on u-boot as i
never see kernel heartbeat blink the blue-LED and i dont have
UART/Serial/USB cable yet (placed the order for one). SD card is fine
(Sandisk Ultra, fresh, have tried with Armbian and Hardkernel's Ubuntu
images) and is new.
If i had the UART, i'd probably know where it gets stuck. If you do have C2
- can you try building / burning vanilla config (i made 0 modifications)
and see if it would boot on yours ? i doubt it.

tx !
