[ROM][LineageOS 17.1][Android 10.0][voodik] for the ODROID-C4

[joerg]

No, I have not flashed the dtbs. And yes, I used voodik's defconfig and enabled the DS1307.

[mad_ady]

I'll check my build environment (probably on monday) and report back.

[joerg]

Yes @mad_ady, normally it is not needed to replace the modules if the kernel version stays the same.
As I installed some weeks ago Alpha-v0.4, this branch test5 should be the correct one. I will make some more tests, but to replace the kernel modules I have to totally dismount my C4 to get the emmc .

[edit]
I have compared the logs and this is the first bad message with my kernel:

Yes. Lot of modules, like mali, media omx and also wifi drivers not included in kernel tree. This modules building separate in Android build process.

[joerg]

OK, but what is the solution then? This modules that are built in Android build process should also be compatible to the kernel I am building. As I see in Kernel-Version, your version is 4.9.113 #2 Thu Nov 12 18:57:54 WITA 2020.
As I was wondering before, if I use different toolchain, or if I compile the kernel out of Android tree, can this be the thing why it is not working?
This is how I compiled:

Code: Select all

export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-
export PATH=/home/joerg/Development/odroid_n2/toolchain/gcc-linaro-6.3.1-2017.02-x86_64_aarch64-linux-gnu/bin/:$PATH
make odroidc4_android_defconfig
make -j12

And I tried also the toolchain gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu
Toolchains gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux and lineage/prebuilts/clang/host/linux-x86/clang-r383902b are failing.

[mad_ady]

I think my last kernel compile (about a month and a half ago) was done with this toolchain: gcc-linaro-6.3.1-2017.02-x86_64_aarch64-linux-gnu.
The dtb flashing steps here are no longer correct: https://magazine.odroid.com/article/run ... r-android/, but otherwise the steps are about the same. I used voodik's fork, with this branch: lineage-16.0_odroidg12_64_test4 (BUT NOTE - this was for an N2, not C4!)

BTW.
Did you change config ? or dtbs only ?
if you enable some drivers in config yes kernel should be flashed, if only dtb modification you can flash only dtbs partition.
Maybe I can help you and build kernel for you? I can provide you boot.img and /vendor/lib/modules folder. just replace modules flash kernel and after do any modifications with dtb and flash dtb only...

[joerg]

I have replaced the kernel compiled with this toolchain when it was Alpha-v0.1. It was working.
I check if I am on the right branch:

Cleaning the kernel source and compiling again. The same.
If it results that we cannot replace the kernel, it would be meaning that we need to ask @voodik if he provides a new update. But it is not what I want, to charge others with my whishes.

[joerg]

As I need my C4 now in the car and no one seems to trying out, if the kernel can be replaced, I have now compiled ds1307 as loadable kernel module and placed it in /vendor/lib/modules.
This is basically working, but not so optimal as inbuilt module.

I need to load the module from /vendor/etc/init/hw/init.odroidc4.rc with insmod /vendor/lib/modules/rtc-ds1307.ko in trigger section on boot.

First:

Code: Select all

[    1.476908] hctosys: unable to open rtc device (rtc0)

The module is loaded to late.

Then:

Code: Select all

[    5.885400] rtc_ds1307: disagrees about version of symbol dev_warn
[    5.885422] rtc_ds1307: disagrees about version of symbol _dev_info
[    5.885440] rtc_ds1307: disagrees about version of symbol dev_err

The kernel modules need to be compiled against Module.symvers. But it's only a warning, the module loads.
Obviously the reason why Android don't boot with the custom kernel?
Need to learn how to compile correct.

Next:
Made a custom dtb overlay for DS3231, modified the makefile and compiled it.
But to unpack the dtbs partition and repack with the additional dtbo does not work.
The dtbs.img created with mkfs.cramfs is about 50% shrinked, means compressed.

It seems that it is not compatible, obviously when u-boot tries to load it.
Android build system has other method to compile it.

Finally:
I added the necessary part into boot.ini:

Code: Select all

fdt addr ${dtb_mem_addr}
fdt mknode i2c0 rtc@68
fdt set i2c0/rtc@68 compatible "maxim,ds3231"
fdt set i2c0/rtc@68 reg "<0x68>"
fdt set i2c0/rtc@68 status "okay"
fdt set /rtc status "disable"
booti ${loadaddr} - ${dtb_mem_addr}

It seems that fdt addr ${dtb_mem_addr} must be given again after dtbo reading.
This line fdt set /rtc status "disable" is to disable the virtual rtc module.

[mad_ady]

The difference in dtb size is that the original dtbo partition is 128k in size and you read it with dd. There's some free space after it.
You can try zeroing kernel and dtbo before flashing them, though that wasn't necessary for me on the n2.
And run file on the kernel/dtb and compare output with the originals.

[joerg]

@mad_ady: Merry Christmas and also to all other.
Then it is interesting why it does not boot when I flash it. I do nothing else as unpack it and add a small dtbo and pack it with mkfs.cramfs again. I flashed it by dd to dtbs partition. To try it with fastboot I have to disassemble the C4 again. I will see if I do, or if the solution I found works so far.

[mad_ady]

Try to mount cramfs without unpacking it. I don't remember, but the fuse driver might be smart enough to repack the cramfs for you.

Hey everyone!
I'm using this OS on a C4 I've given my inlaws that live in a different town.
It has an Odroid Wifi 5 module attached (not 5A).
I've installed one of the original releases and updated it twice (not the last update yet though), but I have two problems that weren't present before the updates.
1. WIFI doesn't automatically reconnect on boot. Once wifi disconnects, it doesn't automatically reconnect again. The AP isn't hidden and can connect manually. Not sure how to force it to scan or connect automatically.
2. I'm using Openvpn for Android to connect automatically when there is a network connection back home (for troubleshooting). It used to connect, but no longer connects automatically after the updates, although it's set to do it. It connects manually, though.

Any suggestions on what to try to troubleshoot next time I'm there? Should I try to wipe cache from recovery? Collect some logs?
Can't do much remotely, my inlaws haven't managed to turn on wifi themselves
Thanks!

Is your module directly connected to USB 3.0 port ?

[mad_ady]

No, it's through a 1m usb extender and it's connected to the usb-otg port in order not to interfere with the usb hdd that is connected to a usb3 port. Also, it's about 1m away, for better reception. I'll try to move it closer and switch ports if you think it will make any difference,
