 Posted: Sat Feb 18, 2017 7:19 pm Post subject: Banana Pi M2-Ultra with Gentoo - u-boot misunderstood |
 |
|
Hi, I've managed to run Gentoo on mentioned SBC.
I'm following this document:
https://drive.google.com/file/d/0B_YnvHgh2rwjenBWVE1fTDVFVjg/view
With many inspiration from here:
https://wiki.gentoo.org/wiki/Banana_Pi_the_Gentoo_Way
My steps so far:
1) toolchain
| Code: | crossdev -S -P -v EXTRA_ECONF="-march=armv7-a -mfpu=neon-vfpv4 -ffast-math" -t armv7a-hardfloat-linux-gnueabi
emerge -av u-boot-tools |
2) bpi-tools + kernel
| Code: | $ mkdir bananapiM2U
cd bananapiM2U/
mkdir tools
cd tools/
git clone https://github.com/BPI-SINOVOIP/bpi-tools.git
sudo cp bpi-* /usr/bin/ |
| Code: | git clone https://github.com/BPI-SINOVOIP/BPI-M2U-bsp.git
cd BPI-M2U-bsp/ |
3) upgrade bpi-tools
4) build all
| Code: | ./configure BPI_M2U_1080P
nano -w Makefile
CROSS_COMPILE=armv7a-hardfloat-linux-gnueabi-
./build.sh
1 |
5) prepare SD card
| Code: | fdisk /dev/sdx
-150MB FAT32
-rest Linux
sudo mkfs.vfat -n BPI-BOOT -F 32 /dev/sdx1
sudo mkfs.ext4 -L BPI-ROOT /dev/sdx2 |
6) | Code: | | sudo bpi-bootsel BPI_M2U_1080P.img.gz /dev/sdx |
output:
| Code: | Warning: Try to write to BOOTDISK /dev/sdx
umount device: /dev/sdx
##########################
# Burning the bootloader #
##########################
sudo gunzip -c BPI_M2U_1080P.img.gz | dd of=/dev/sdx bs=1024 seek=8
102392+0 records read
102392+0 records wrote
104849408 bytes (105 MB, 100 MiB) copy, 28,2654 s, 3,7 MB/s
OK!! You can remove the BOOTDISK /dev/sdx now!! |
And there is the misunderstood - When I remove SD card and push it back I can't mount sdx1 - there is no filesystem.
Am I doing something wrong? Could someone show me the right way?
Thanks in advance |

DeIM,
As it stands, thats horribly hackish and I can see why it may not work.
You use fdisk to make partitions and filesystems on the partitions.
Then you dd something into the boot partition by skipping the first 8k of whatever is there.
| Code: | | sudo gunzip -c BPI_M2U_1080P.img.gz | dd of=/dev/sdx bs=1024 seek=8 |
That 8k shouid contain your partition table (it does, you made it) but if your partition table and the one in the image need not be aligned, you won't be able to find the tilesystem to mount.
Decompress BPI_M2U_1080P.img.gz then loop mount the resulting file. Th should be a filesystem in a file.
Copy the entire content to the mounted /dev/sdx1 (SDCard partiton 1.)
Now the partition table alignments don't matter as you are working with files, not raw disk blocks.

A perfect example why a wiki needs QA. And this guy really did not understand how it works.
Not needed in the first place regardless what is done later.
When you "initalize" "correctly" a "block device" there should be no need for that! |

Nice board, even if it is not really related to the original bananaPI .....
Did you tested the SATA port? Apparently is speed limited ....
Also automatic irqbalancing is not working also on allwinner SoC, but you can manually assign IRQs to different CPUs, it makes a difference...

There may be the source of problem:
| Code: | file *.img
BPI_M2U_1080P.img: data
sudo fdisk -l *.img
Disk BPI_M2U_1080P.img: 100 MiB, 104849408 bytes, 204784 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
sudo mount -o ro,loop BPI_M2U_1080P.img /mnt/dvd/
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so. |
This output is the same for built image and for official from github:
https://github.com/BPI-SINOVOIP/BPI-files/blob/master/SD/100MB/BPI_M2U_1080P.img.gz |

It seems to be my fault 
First partition didn't start at 204800 which is the end of first 100MB for uboot.
Thank everyone who replied. |

OK, it's booting now.
There is dmesg from first boot:

This is my first BPI, so anybody with tips is welcome 
Looking forward to test SATA and SD speeds... |

I am curious about performance, you know for my next board ......
According to sunxi wiki read speed of the A40 should be capped at ~200 MB/s and write speed ~45MB/s, irqbalancing helps to squeeze a few of MB/s more
I use this script, adapt it to your /proc/interrupts, the sata driver on your board should be called ahci
| Code: | #!/bin/sh
for i in $(gawk -F":" '/emmc/ {print $1}' </proc/interrupts); do echo 2 >/proc/irq/$i/smp_affinity; done
for i in $(gawk -F":" '/dwc_otg/ {print $1}' </proc/interrupts); do echo 4 >/proc/irq/$i/smp_affinity; done
for i in $(gawk -F":" '/eth0/ {print $1}' </proc/interrupts); do echo 8 >/proc/irq/$i/smp_affinity; done

| Is it possible to have F2FS on SD as rootfs? I didn't find much information about it only that u-boot doesn't support it, but if I have built it in kernel? |

| Yes. U-boot likely doesn't support loading a kernel from F2FS, you could chain a kernel which has F2FS from a VFAT or ext2/4 /boot. |

Something needs to load U-Boot too.

Hi, I'm back with this device. I need to get it as stable as possible - problem seems to be with USB.
Significant problem is, when I connect two USB disks to powered hub - it very soon makes error, disconnects and it's far from stability.
I thaught it's problem of specific drive so I leave one that seem stable on powered hub and it seemd to run well, but it makes errors also but with lower interval.
When I connect cable from USB hub (same power, same disks) to computer, disks works well.
Is there a way how to determine the source of problems? I have tried different cables also. Problems seem with BPI only.
typical kernel messages:
| Code: | Oct 7 12:06:00 bpi1 kernel: hub 1-1:1.0: cannot reset port 4 (err = -110)
Oct 7 12:06:05 bpi1 kernel: hub 1-1:1.0: Cannot enable port 4. Maybe the USB cable is bad?
Oct 7 12:06:06 bpi1 kernel: hub 1-1:1.0: cannot disable port 4 (err = -110)
Oct 7 12:06:25 bpi1 kernel: sd 1:0:0:0: Device offlined - not ready after error recovery
Oct 7 12:06:25 bpi1 kernel: sd 1:0:0:0: [sdb] Unhandled error code
