XU4 will not boot - red light, no other activity

Unread post by flavor8 » Sat Nov 16, 2019 9:55 pm

Hello,

I just received an XU4, and it will not boot.

* I'm using the power adapter that comes with it
* Using EMMC, connected to the back of the board
-- Initially tried with the stock Ubuntu image that came flashed
-- Reflashed it with Ubuntu 16.04 downloaded from odroid.com
* Boot switch is set to EMMC
* Have also tried it with the SD EMMC reader, with boot switch set to SD

In all cases, the red light comes on when I connect power, but nothing else happens.

I don't have a USB-UART kit, but I did open the EMMC using the USB reader on my computer and could validate that the filesystem was browseable, at least. There was no updated logging in /var/log/syslog.

Any further suggestions?

Thanks

Thanks for the suggestion, but same issue persists after doing that.

Code: Select all

sudo dd if=./ubuntu-18.04.3-4.14-mate-odroid-xu4-20190929.img bs=512 count=$((`stat -c%s ./ubuntu-18.04.3-4.14-mate-odroid-xu4-20190929.img`/512)) | md5sum

Please flash the OS image(ubuntu-18.04.3-4.14-mate-odroid-xu4-20190929.img.xz) with Etcher. Don't extract the xz file.
Boot switch must be at "eMMC" and connect the eMMC to the bottom of the board.

If you have a spare micro-SD card, please try it to narrow down root causes.

I will, but it'll take a few days.

In the meantime: is the checksum from the card that I'm showing wrong? It matches the actual image. Why will Etcher make a difference?

The md5sum values are correct. But I don't know whether the dd destination node is a disk or a partition.
So I recommended Etcher.

I think you did as much as you could.
Please contact "odroid at hardkernel dot com" with a link of this post.
They will help your RMA process if you purchased the board from our web-store directly.
Otherwise, contact your local distributor/reseller.
Sorry for the inconvenience caused.

The XU4 is fine. Turns out that the eMMC module can't boot. I bought an SD card, imaged that, and can boot that.

Why would the eMMC be unable to boot (despite multiple attempts, with etcher and dd)?

Do you have an Orange eMMC? or the other one?

Yeah it's an orange one.

It has a red circular sticker on the chip with some kind of cartoon figure on it.

In that case, the eMMC connector or eMMC bus on the XU4 board might be damaged probably.
