[MTk 7632n] BPI-R2 + Openwrt 18.06.1 = Only have 0kb available on filesystem

For Developers
#1

Hello.
I flash to boad OpenWrt 18.06.1, r7258-5eb055306f from https://downloads.openwrt.org/releases/18.06.1/targets/mediatek/mt7623/
and when I tried to install the package I got the error: Verify_pkg_installable: Only have 0kb available on filesystem /overlay, pkg nano needs 63
I assume that you need to increase the amount of free space in the firmware or include resize2fs in it by default.
But I can only test image and report.
Is it possible to solve the problem myself, or do I need to wait for the release of the update from the OpenWRT team?

For some people nano is bloadware, try out vi, its very good! Don't take me seriously! Nano is fine.
I wonder why mtk7623 should'nt use overlayfs..
Try out a older build..
MTK7623 or 7632?
BPI-R2 is 7623 so should be the correct image.

What old image can I try? And how can I find a person who understands how Openwrt is compiling and ready to spend a couple of hours to talk with me(I not understanding either programming or English) :grinning:

#4

Did you use the initramfs or squashfs version? I don't think the initramfs image will be able to store anything permanently. Did you put it on a completely empty storage device with no existing partitions?

#5

here are the different releases for download:

Direct link to 18.06.0 build for BPI-r2:
bpi-r2-18.06.0
for 18.06.1
18.06.1 sqashfs

I used the initramfs version. The device memory is divided as follows:

:/# fdisk -l /dev/mmcblk0
Disk /dev/mmcblk0: 7.3 GiB, 7818182656 bytes, 15269888 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xffffffff

Device         Boot  Start      End  Sectors  Size Id Type
/dev/mmcblk0p1        2048    12287    10240    5M 83 Linux
/dev/mmcblk0p2      135168 15269887 15134720  7.2G 83 Linux

other images contain a similar structure, when I view a hexview, I do not see the file system.
For example: The release of the x86 platform contains a file structure in a separate file https://downloads.openwrt.org/releases/18.06.1/targets/x86/generic/rootfs-ext4.img.gz

In the releases of LEDE compiled by the Chinese manufacturer, the file system is visible in the images.

#7

When you compile you can choose which images you like to generate at the end. Dig yourself through the menuconfig, you'll need the knowledge when you like to use openwrt seriously on such a device . Then you can configure the Image size and so many more
I would recomment to use squashfs with a overlay. you will be more fault tolerant with overlayfs.

#8

unfortunately , cross-compilation in buildroot is too difficult task for me

#9

Use the squashfs version. As you can see the flash disk does not get mounted when you use initramfs, and I don't know if there is an easy way to do it.

#10

If the squashfs version doesn't mount anything either you may be better off making your own image and select ext4. It's easy if you have Linux: https://openwrt.org/docs/guide-developer/quickstart-build-images
and not very difficult using Windows or another OS that supports Virtualbox: https://openwrt.org/docs/guide-user/additional-software/beginners-build-guide

From this study, I learned the difference between the versions of initramfs and squashfs.
Because first 2 megabytes is occupied preloader and Uboot, I flashed a squashfs corresponding shift:
dd if = openwrt-18.06.1-mediatek-mt7623-7623n-bananapi-bpi-r2-squashfs-sysupgrade.bin of = / dev / mmcblk0 bs = 1M seek = 2

I received the following error when loading:

[    1.510376] VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6
[    1.517797] Please append a correct "root=" boot option; here are the available partitions:

[    1.559827]  (driver?)
[    1.566562] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

if I'm not mistaken, the root-filesystem should be on the squashfs section. but neither in initramfs nor in squashfs contains the signature "hsqs" denoting the beginning of the squashfs section. So in both images does not exist the root-filesystem ? Is that enough to open the issue?

I would very much like to get a working image from the openwrt site to facilitate future updates and ensure the compatibility of the opkg repository

#12

I suspect the R2 isn't properly supported. Everything about the images seems very generic compared to the other banana pi releases. https://openwrt.org/toh/start?dataflt[Model*~]=banana&dataflt[Brand*~]=

@tonyich
I am compiling a ext4 version and send you a link for the dwonload!
Openwrt has the easiest Buildsystem i ever used .I recommend to use it! It is more difficult to compile your own linux kernel for debian or to install a debia from scratch with a minimal-iso!
Ill post the link soon !
It will be a 18.06.1 stable release if you want a master as well.,.
Done:
These files will be deleted in 7 days

Thank you very much for the help! But either I do something wrong, or the problem is a bit more complicated:

It seems to me that initramfs contains a minimal filesystem in itself, to run the kernel. And that the external file system is mounted, after boot kernel, need to fix / etc / fstab inside the initramfs.

Ok i did something wrong will compile a new one!!
I was kinda stupid not to read about the bpi-r2 first..
Do you boot from emmc flash chip? or micro sd?
i need to know in the openwrt buildroot is a script for generating the emmc image, i can create that. Could be still a problem without the bootlaoder. I see that bpi-r2 is not ported to openwrt, it is ported to lede. I never mess around with lede i sticked to openwrt, but i could port it to openwrt in a fork. ATM i have not the time to do so. I will generate a emmc flash image for you and go on with my labour. Sry for my english

#17

Thank you very much for your work! My English exist only through Google.
I'm loading from emmc. so as not to damage the loader, I'm skipping 2 MB

#18

So, here i am again..
I tried to understand the original bpi-r2- lede repository and tried to port their work to openwrt, kinda stupid what i did but i made two images hopefully working ones.


The images are with uboot..
I recomment to try the SD-Card version first, when you know how to write a new bootloader to the rpi-r2 emmc try the emmc one
gluck i realy dont know if this works..
You see they are both equal so there should be a difference i think. But give it a try they are both with preloader, uboot, kernel, rootfs...

i see a command prompt in your post pls enter printenv if possible and send me output..
perhaps entering boot is enough.. to boot

from http://forum.banana-pi.org/t/topic/3878/42

1. Copy EMMC image to a running system which is on SD card
2. Program EMMC image to User Data Area of EMMC: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0
3. Unlock EMMC boot0 block: echo 0 > /sys/block/mmcblk0boot0/force_ro
4. Program preloader to EMMC boot0 block:
     dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0boot0 bs=1M count=1
5. Change the Partition configurion of EMMC is 48h: reboot the system which is running SD, and enter the U-boot command line, run command
    emmc pconf 48
6. Power off, remove SD card, and then power on R2 board.
