Odroid-N2 on archlinux cannot boot on using linux-next on sd_card / emmc

Hi Niel,

I am not able to boot using sdcard / emmc module with
*linux-next-20190624* kernel on my Odroid-N2
when I want to boot using archlinux distro.

FYI Sdcard is (Sandisk 32 Class 10)

I am using the u-boot [0]
[0] https://github.com/superna9999/u-boot/tree/u-boot/topic/odroid-n2

I have check the sdcard is detected at the u-boot prompt but booting
linux kernel it fails.
Here is the logs of the u-boot.
[1] https://pastebin.com/wA9fAVJ0

Here is the boot log for linux-next-20190624

[2] https://pastebin.com/ajRkNR0e

I feel this crash is because of SD card is not initialized.

I tried to reconfigure the dts with following patch after looking into
schematics.

odroidn2_sdcard.patch

Can you give me some hint on how to resolve this issue ?

Best Regards
-Anand

Yes it's expected, the missing clocks were only merged today (cf
[GIT PULL] clk: meson: update for v5.3) and will appear in the next linux-next.

Thanks for this input, I will check this with the latest linux-next.
And then check my changes are valid.

I think the clk change have being merged into linux-next-20190626
but still I am not able to get this pass the detect of *sd_card* or *eMMC*

Here are the log: https://pastebin.com/Sw0wA4nM

Any input for me to look into this?

Best Regards
-Anand

Probably more FYI than useful input, but at least in kernelCI, odroid-n2
started booting succesffuly as of today next-20190626:

Thanks for your input, I am able to boot my Odroid-N2 using eMMC.
But still I am struggling to get this booted using microSD card.

Right now it not stable, cannot get any thing to work or test

Re: Odroid-N2 on archlinux cannot boot on using linux-next on sd_card / emmc

[Anand Moon]

Hi Neil,

[Ship]

Sorry for not following on my query on not able to boot from microSD
card on Odroid N2.
I have been trying various changes in *meson-g12b-odroid-n2.dts* most
of them related
to linking the power to tflash_vdd and tf_io nodes.

From the schematics it seems
tflash_vdd (TFLASH_VDD_EN)   vin-supply = <&vddao_3v3>;
tf_io (TF_3V3N_1V8_EN)           vin-supply = <&vcc_5v>;

but it seen some thing core is missing in Initialization of tf_io.

Below regulator_summary confirm my finding ft_io not linked to any
main regulator.

[root@alarm ~]# cat /sys/kernel/debug/regulator/regulator_summary

Also I could not figure out how Hardkernel (Amlogic) source code
initialize the power for regulator.
If you could share some input I will then try to debug this future.
