Cubox-I 4 with Legacy an Mainline Kernel is not booting by using PARTUUID or UUID in boot.cmd

February 22, 2017, 1:20 pm

Hello,

 

i was using my cubox-i 4 pro since two years now. Last time (last week) i have used a armbian legacy debian version from whatever, after my hdd corrupted (i have a backup) i tried to setup the system again with a new ssd and the newer version of armbian but i have a few problems.

 

First i flashed the mainline 4.9.7 dd-image on my sd card with rufus. That one is not booting. I can see in a seriel session that the uboot is starting after the line booting the kernel nothing happens any more. In my router i can not see any ip from dhcp is given out to the system and it does not do anything more.

 

After that i have tried the legacy 3.14.79 what when i flashed it to the sd card did boot. After that i tried to insert the partuuid of my sd card because i want to use it with my ssd over esata and two more usb hdd as sw-raid1 where i do not want to have any problems in booting situations. I have tried to to exchange the variable in boot.cmd defaultly declared with "/dev/mmcblk0p01" with "PARTUUID={PUUID}" what did not do the job. The system wasn't anymore booting with this setting. After that i tried using the uuid of the mmc by declaring the variable in the boot.cmd wit "UUID={UUID}" (all the time i wrote the ids which i wrote here in brackets natively in the string, with double checking if i had some spelling mistakes). I did as well all the time recompile the boot.cmd with the defined line at the end of the boot.cmd.

 

After trying to exchange the content of the variable i tried to exchange the variable in the bootargs string natively with the content of the two version of the variable definition what as well did not do the job to boot my cubox.

 

So now i'm asking, what am i doing wrong? I'm just searching for a solution to us the uuid or the partuuid of a hdd or sdd to boot my system so in the future no conflicts at boot appears with the further usage of more hdd's connected via usb to the box.

 

Hopefully my description is understable and some one can help me.

H3 SPI with DMA using kernel 4.10.0

February 22, 2017, 6:31 pm

Using the dev build of Armbian for the OrangePi One, does the SPI driver in the mainline kernel support DMA?

According to the mainline status page the work on SPI is done, and DMA has been supported since 4.2

 

I have enabled the spi interface in the device tree and my driver initialises properly with the master.  But in my kernel driver I attempt to allocate some memory with dma_alloc_coherent and it fails.  The driver works fine with the legacy kernel and with alternative hardware (raspberry pi). 

 

Is there some additional configuration needed or does anyone have any pointers to information on this that I look at?

OrangePi Plus/plus2 kernel 4.10

Hi,

 

Following the guide https://docs.armbian.com/Developer-Guide_Build-Preparation/  I compiled a kernel 4.10 and I get:

 

[*]  Only appears one CPU.

                          CPU1, CPU2, CPU3 show disabled as lshw result.   Anybody know how to enable the other cores?

 

[*] In kernel config I enabled staging drivers for sun8i crypto engine. It seems that 

                          after loading the module,  cat /proc/crypto does't appears to be using the crypto engine. 

                          openssl speed seems to be the same than legacy kernel.

                          In dtb I can see that there is some stuff about crypto with status: disabled

                          Anyone can help in getting the crypto engine enabled?

 

 

 

[*]  wifi: The iface wlan0 doesn't exists in kernel 4.10. but after compiling 

                        git clone https://github.com/jwrdegoede/rtl8189ES_linux.gitfrom from http://linux-sunxi.org/Wifi

                        the wlan0 appears and I am able to scan wifi... but there is a error when trying to associate with WPA-PSK CCMP 

                        so no wireless connection.

                        Anyone can point how to make it work?

 

 

Greetings

USB-touchscreen doesn't work with Cubietruck 3.4.113.

The touchscreen well works with versions 4.9.xxx, but doesn't work with 3.4.xxx.
I connected the monitor 1920*1080 and a touchscreen to Cubietruck.
Cubietruck smartly works in video browse mode, but the mouse and the keypad aren't always convenient for control.
Especially at night, too loud clicks. 
I pasted a touchscreen on the monitor.
It works with versions 4.xxx, but video doesn't work. And with versions 3.xxx on the contrary.
What I should make that the touchscreen worked with version 3.4.113?

Hello,

 

My project does not allow me to use SD card to boot and run my application. I can use SD card as drive to save my data.

 

Is there any alternative way to do so ?

 

Has anyone built a micro rootfs for O-Pi-ZERO NOR Flash ?

 

Does anyone have an idea of the MINIMUM SIZE that is required to do so, if 2MB is too less ?

 

Thanks

Hi!

I want to write SPI slave custom driver for H3. For this I need to cut off existing SPI Master driver. I did this during configuring Armbian 3.4.112 in image build process. But then I make apt update/upgrade and apt installs new image 3.4.113 with SPI master driver enabled. How could I prevent this?

USB Devices on 5.25 doesn't work well

Hello I have a little problem with the usb devices, i use usb camera and if u plug the power supply to the OPI Lite board (5.25) it recognize the camera but it doesn't work well (stream with like 8-10 fps), after a software reboot, the device go to other Bus and the camera work fine with 15-30 fps stream.
 
Before reboot, exact on first power of the board:
 
Bus 006 Device 002: ID 058f:3822 Alcor Micro Corp.
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
 
 
 
After reboot:
 
Bus 003 Device 002: ID 058f:3822 Alcor Micro Corp.
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
 
 
I try to remove and after that load again uvcvideo driver, but nothing happened, i tried some scripts to restart the usb ports but the result was 0, only if i unplug and plug the camera again or reboot solve the problem. Also i tried with different power supplies and nothing changed. Currently we use chargers from the Orange Pi manufacture so this is the best power supply i guess.
 
 
Any ideas how can i configure the camera to be on Bus 3 and tha wifi dongle to be on Bus 2 or some other solution to the problem?

Here's how I tested communication with UART. I wired up the pins (RX <--> TX) as per the pinout at http://linux-sunxi.org/Xunlong_Orange_Pi_Zero#Locating_the_UARTI would then do,

[Odroid C2] filesystem corrupted after boot from emmc

February 24, 2017, 1:11 pm
$

I created a new image for my Odroid C2 with the most current version of Armbian 5.26. Configuration was pretty much standard, except BOOTSIZE=0 and ROOTFS_TYPE=ext4. The image works fine, if dumped to a sdcard. When dumping it to an emmc card, the system boots up, but 'find / > /dev/null' leads to a filesystem error:

 

[   52.799920] EXT4-fs error (device mmcblk0p1): htree_dirblock_to_tree:913: inode #41001: block 12032: comm find: bad entry in directory: rec_len % 4 != 0 - offset=0(0), inode=8213, rec_len=4097, name_len=0
[   52.812862] EXT4-fs (mmcblk0p1): Remounting filesystem read-only

 

Behavior is deterministic - I tried with two different boards and two different emmc cards. I also checked, that the filesystem is initially ok on the emmc.

 

I tracked the problem down to the Amlogic mmc driver in linux kernel 3.14.y. During kernel boot, the function aml_sd_emmc_execute_tuning in drivers/amlogic/mmc/aml_sd_emmc.c is invoked. pdata->need_cali == 1 and aml_sd_emmc_execute_tuning_index is called. At the end, this function writes to the emmc: mmc_write_internal(mmc->card, record_blk, 1, write_buf).

The first two bytes of the written data are 0x2015, 0x1001 - which perfectly corresponds to the inode and rec_len from the error message above.

The position where the data is written at is calculated in emmc_partitions.c (function get_reserve_partition_off) and depends on several constants. The position evaluates to block #98304, which is somewhere in the root partition of the disk. Since in my image, this block is used by a directory inode, the filesystem gets corrupted.

 

On an image with a 64MB boot partition and an ext4 root partition, the write operation goes to the boot partition. It does not seem to have a negative impact on the consistency of the filesystem - at least not in my case.

 

I could imagine different solutions of the problem:

(1) set OFFSET=64 -> write operation will go to the unused space before boot / root partition

(2) change constants in linux kernel -> write operation will go to a different block on emmc (i cannot guess potential side effects of this)

(3) change partition layout on emmc by changing calculation in debootstrap-ng.sh

 

 

Best regards,

Michael
