i.MX53 QSB

[ckhmer1]

Hi All,
I have two i.MX53 QSB and i'd like to install archlinux on them.
I know that the USB Armony has a i.MX53 SOC on it, and archlinux support it.
Indeed I've successfully installed and booted that distribution on my QSB.
Unfortunately there are a lot of kernel modules missing.
For example, the wired network is not working. The two USB are not working.
The USB should be the following:
- ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
The Ethernet should use the g_ether and fec drivers.
I didn't try if SD card reader or GPU have the modules.
I'm wondering if there is a way to have all missing kernel modules for the QSB, in order to install and use archlinux (with update) on my QSB.
Thanks for helping.
Claudio

g_ether is there, as well as likely the FEC.

The display drivers are there for the iMX53, and that I know because I had to disable them with a blacklisk on the Armory.

Get a list together of anything you are truly missing, and provide us that in terms of kernel config options, and we'll see what we can find. The QSB should have a mainline DTB, so in that regards, everything should be cleanly described and all drivers should be present.

Hi,
thanks for your reply.
Using the ubuntu ditribution build using the instruction on https://eewiki.net/display/linuxonarm/i ... uick+Start, i've following output of the command lsmod

I've loaded the same modules on ArchLinux ARM harmory and lsmod gives me following:

Some missing modules are builtin.
I'm not able to use USB, ethernet, SD Card reader (and maybe other) using archlinux.

Using ubuntu, the lsusb command gives me following:
Bus 001 Device 004: ID 045e:0029 Microsoft Corp. IntelliMouse Optical
Bus 001 Device 003: ID 046d:c30f Logitech, Inc. Logicool HID-Compliant Keyboard (106 key)
Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

instead archlinux the output is empty.

I'm only able to connect via serial port.

If you need I can post the output of the dmesg command.
What I can check and do in order to make the QSB working?
Thanks

What kernel package, and what DTB are you using?

[ckhmer1]

Hi,
the kernel is "Linux version 4.3.0-2-ARCH (builduser@leming) (gcc version 5.2.0 (GCC) ) #1 SMP Wed Nov 18 21:42:39 MST 2015"

how to check the DTB version?
Thanks

Check your uboot environment and any script in use.

[ckhmer1]

Hi,
because I was running the distro for usbarmory "fdtfile=imx53-usbarmory.dtb" in u-boot because the u-boot is build for usbarmory.
I've downloaded the u-boot source code and build it for i.MX53loco.
Unfortunately I didn't find the u-boot archlinux patch and when the board try to boot i have following error:

U-Boot 2015.10 (Jan 06 2016 - 22:11:36 +0100)

Booting from net ...
BOOTP broadcast 1
BOOTP broadcast 2

I guess that the original u-boot is using boot and root partitions, instead archlinux use only one partition.

I've tryed to symlink the boot.scr and zImage files on the root and I get following errors:

U-Boot 2015.10 (Jan 06 2016 - 22:11:36 +0100)

Should I build a new zImage? Is so, how to do it?
How can I resolve this problems?
Thanks

The patches are in our github PKGBUILDs, and all configuration changes. You will need to make the necessary changes for it to work for the "loco"

[ckhmer1]

I'v serched on https://github.com/archlinuxarm/PKGBUILDs/. There are several packages for imx, but only the u-boot for usbarmory https://github.com/archlinuxarm/PKGBUIL ... ster/alarm.

Is there another repository where I can find the u-boot PKGBUILDs for i.MX53 LOCO board?

[WarheadsSE]

We do not have a specific package for the loco board, I don't know why you keep thinking we magically do.

Use the armory ones and rework the patch set, as I said.
