Issues Booting from SD

jcst18 · Unread post by **jcst18** » Wed Sep 11, 2019 1:52 pm

Hi, I've been having difficulties using the SD slot on my N2. I was attempting to update Petitboot but the files were never recognized off the SD in both upgrade and recovery mode. I tried to boot Ubuntu off the SD card set to MMC but that doesn't work either (nothing to provide off the UART logs.. blue light doesn't even come on). I'm pretty sure there's a hardware issue, which would be pretty unfortunate. Any help would be appreciated.

Boot Ubuntu from eMMC without SD card.
After booting, plug an SD card and capture "dmesg" output and post it here to find a root cause.

If you can get the shell from Petitboot, please do run the command and share the output while your SD card is attached.

# ls -l /dev/mmcblk*

Update: I formatted the card and flashed Ubuntu minimal again.. those errors disappeared from output but it still can't boot off of SD.

Weirdly Petitboot is now finally recognizing both OS on the eMMC.. absolutely no idea how that happened or how it was related to the SD because it never worked before.

EDIT: Nope.. gone from Petitboot again. Not even sure how to recreate what happened. Also, new log once I've booted into Ubuntu:

I am not sure if it's a hardware issue or not, what I am seeing from the logs is that your uSD is recognized but detached after many errors. What's the vendor or model of you uSD? It probably works on PC flawlessly, right?

The SD card slot/interface look okay at least. So it seems not to be a hardware issue probably.

Did you change the boot mode slide-switch and remove the eMMC?
Do you have any other SD card for testing?
Could you see any UART message something like this?

This is actually the second micro SD card I'm using. The first one had problems as well but it turned out to be a knockoff. This one is a Samsung EVO Select, just purchased and works perfectly on my PC.
I did change the boot switch and the UART displays:

The card seems to be detected but SoC couldn't read boot blobs probably.

Did you flash ubuntu-18.04.3-4.9-minimal-odroid-n2-20190806.img.xz image with Etcher?

Yeah, that's what I used.

Sorry for my late response.

<1> If there is a bootable SDcard in the slot, I could see this message.

Code: Select all

G12B:BL:6e7c85:7898ac;FEAT:E0F83180:2000;POC:F;RCY:0;EMMC:800;NAND:81;SD?:0;SD:0;READ:0;0.
bl2_stage_init 0x01

<2> If don't plug a card, I met this one.

Code: Select all

SD?:20000;

<3> If I plug a non-bootable SD card, I can see this one.

Code: Select all

SD?:0;SD:0;READ:0;CHK:1F;USB:8;

Can you compare the messages once again?

Your previous message seemed that the SoC couldn't detect the card insertion due to uncertain hardware problem.
In that case, 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.
