Building a kernel 3.12-rc2 for the imx23-olinuxino
« on: September 26, 2013, 07:38:43 AM »
Repository https://github.com/koliqi/imx23-olinuxino is updated with new branch 3.12-rc2.
Instructions for how to clone branch and build kernel are at http://g-lab.ca/building-a-kernel-3-12-rc2-for-the-imx23-olinuxino/

This build brings patches to support i2c for imx23-olinuxino board's and also audio driver for i.MX23 SoC. You can use those patches also to build kernel 3.12-rc2 to boot with u-boot loader. In this case, instructions to build kernel are at http://g-lab.ca/u-boot-bootloader-for-imx23-olinuxino-board/

there is weird problem with the USB in Kernel 3.x
imx233-OLinuXino-MINI-WIFI with Kernel 3.xx when USB devices is plug on SOME boards the USB gives error -71 and stops working

same boards which do not work with 3.X kernel work fine when boot with Kernel 2.6.x

any idea what may be wrong?

Since that occurs only on imx233-OLinuXino-MINI-WIFI, I am willing to blame RTL81xx driver. We did lot of tests with imx233-OLinuXino-MINI-WIFI and kernel 3.7.1. and everything was OK.  After 3.7.1, wifi driver has been changed.
Please check any "nonworking" board with kernel 3.7.1 and compare result with 3.11.x / 3.12.x.
You can find 3.7.1 image at https://www.dropbox.com/s/rfnmzdbcu21pfgf/sd_mmc_bootstream.raw.

OK, work on imx233 nano, i use u-boot.

But why i have 49 m of free ram, i haven't a 64 m system ?  is for all kernel....  where is my RAM ?

Hello, Fadil,

Did you try to use rtl8188cu patch with 3.12?

I have also the feeling that USB is broken in 3.12-rc2 but works in 3.12-rc1. At least none of my USB WiFi adapters works in 3.12-rc2 but they are working in 3.12-rc1.


Did you try to use rtl8188cu patch with 3.12?
Why not use the driver that comes with 3.12:
Code: [Select]
Device Drivers  --->
      [*] Network device support  --->
        [*]   Wireless LAN  --->
          <*>   Realtek rtlwifi family of devices (NEW)  --->
              --- Realtek rtlwifi family of devices
              <*>   Realtek RTL8192CU/RTL8188CU USB Wireless Network Adapter
              [ ]   Debugging output for rtlwifi driver family

And i2c seems to be broken too:
Code: [Select]
Device Drivers  --->
    <*> I2C support  --->
      --- I2C support
      <*>   I2C device interface
            I2C Hardware Bus support  --->

              <*> GPIO-based bitbanging I2C
              <*> Freescale i.MX28 I2C interface

Why not use the driver that comes with 3.12:

This one doesn't work well with rtl8188CUS chip, at least in kernel 3.11.

Did you try to use rtl8188cu patch with 3.12?
Evgeny,

I did patch for rtl8188cu for build 3.7.1 and worked well. That patch was directly from RTL web site and I did only work needed to be incorporated on new kernel. Later I read somewhere that build in driver work well and I didn't push further that variant.

Quote
I have also the feeling that USB is broken in 3.12-rc2 but works in 3.12-rc1.
Christian,
I see at https://www.kernel.org/diff/diffview.cgi?file=/pub/linux/kernel/v3.x/testing/patch-3.12-rc2.xz  some minor changes on mxs USB driver ( /drivers/usb/phy/phy-mxs-usb.c) but I don't consider those changes to be source of problem.

About i2c. My patch adding i2c support on imx23-olinuxino board and doesn't affect work of i2c driver. There are 3 new patches from Marek Vasut for i2c (distinguish imx23/28 and PIO rework). I didn't incorporate them here because they are still  on i2c mail list waiting for some rework. As soon they get on linux-next, I will incorporate them on build for 3.12-rc2.

About rtl8188cu. My feeling is build in driver is source of problem. Because of that suggested to Olimex to "check any "nonworking" board with kernel 3.7.1 and compare result with 3.11.x / 3.12.x."
If that work on 3.7.1, I am willing to bring again driver from RTL's website  on new build 3.12-rc2

Hi Fadil, do you mean http://www.spinics.net/lists/linux-i2c/msg12844.html:
[PATCH RESEND 1/3] i2c: mxs: distinguish i.MX23 and i.MX28 based I2C controller
[PATCH V2 2/3] i2c: mxs: Rework the PIO mode operation
[PATCH RESEND 3/3] i2c: mxs: Fix PIO mode on i.MX23

I was hoping that i2c would finally work out of the box. I can see that MXS_I2C_V1, MXS_I2C_V2 gets added there to distinguish between i.MX23 and i.MX28. This looks similar to a older patch from Nii https://www.olimex.com/forum/index.php?topic=283.msg2872#msg2872. Hopefully this solves all the i2c problems. I will try to add it line by line.

And sorry I've compiled 3.12-rc2 again and USB is working, can't reproduce my problem, I must have done a stupid mistake somewhere.

Hi Christian,

Yes, I had in mind those patches. Nii did great job at that time but looks hi didn't push on i2c list. Please come back with results if you get together those patches.

Sorry for misinform you. I've just checked the rtlwifi driver, it actually works with 3.12-rc2.
It works only with antenna though, that's why I initially thought it doesn't.
rtl8188cu driver allow me to connect to the network even without antenna.

I've seen somewhere on the internet the statement that rtl8188cu performs better than rtlwifi in terms of signal power or so. I'm not sure whether it's true or not since working without antenna at all is somewhat unusual scenario.

Re: Building a kernel 3.12-rc2 for the imx23-olinuxino

Okay, actually I now just got it to boot successfully by checking over the config and enabling Control Group support.

I'm extremely grateful once again, because I now seem to have an audio driver that behaves far better than in the kernel I tried that's discussed here: https://www.olimex.com/forum/index.php?topic=704.0.
