Kernel cannot find firmware for serdes

Ari Poutanen
Expert 1140 points

Hi,

I cannot get the Kernel to find the firmware for the serdes and dsps. Soon after that the kernel panics, so I think the error has something to do with it.The boot displays the following:

I have now tried several tricks, but haven't so far succeeded in making the kernel to load the firmware bin files.

My board is a custom K2L board. The best I have tried so far:

1. I built a UBI file system image using the K2L rootfs from the MCSDK images "as a template".

2. I added all the firmware binaries the "k2-fw-initrd.cpio.gz" into /lib/firmware in my UBI file system file and checked that "ks2_gbe_serdes.bin" was included there.

3. I built a ubifs file by using the commands mkfs.ubifs and ubinize. The output ubi file contains the following volumes:

boot

uImage.bin

skern.bin

k2l.dtb

rootfs

all the ordinary Linux files + /lib/firmware

4. I flashed that file system into NAND

Mounting it in the u-boot succeeds with the commands

ubi part ubifs

ubifsmount rootfs

I can see files in the file system by using the command "ubifsls". Also the firmware bin files are in /lib/firmware. See the console log above, it is shown also there.

But...when booting the kernel it still does not find the firmware files.

I load the kerlen image and device tree into place with CCS and then boot the kernel by giving the commands:

setenv bootargs ${bootargs} earlyprintk

install_mon 0x0c140000

bootm 0x88000000 - 0x87000000

The kernel starts to boot like in the log above but then gives the error about the serdes firmware and panics.

I prefer booting the kernel from DDR3 for now, because that way I get the boot log on my terminal. If I let it boot from the UBI file system it prints nothing although I use the exactly same uImage binary in both cases. I don't know why.

One more strange thing is that when I run this same kernel in K2H EVM board I complains nothing about the serdes firmware

Questions:

1. How should I tell kernel where to load the firmware?

2. Is it possible at all the boot the kernel like I try to do it now: By mounting the UBI file system with the u-boot and then manually booting with "bootm" command, or is it necessary to boot all the way from UBI only? At lease the bootm command does not seem to provide any link to the file system for the kernel.

Best regards,

Ari

    Seems, you have not loaded the "k2-fw-initrd.cpio.gz" file.
    Can you please try to use the default u-boot env and prebuilt images ?

    Hi, an update to my last post:

    There was an HW mistake with my DDR3. Now, after fixing it, the DDR3 memory seems bemore stable and the kernel boots longer, but panics now in a different point. This time I let it auto-boot completely from the UBI fs. See the log below. The firmware binaries are still not found but it seems be not big a problem. There is some problem with the UBI. The kernel complains it be read-only. Also there is problem in mounting the ubi0:rootfs. Probably I need to check my environment variables in the u-boot regarding to the UBI boot. I put them into the end of this post for checking if you can spot some mistake in them.

    Questions:

    - Where should the k2s_gbe_serdes.bin and the dsp firmware binaries be located in the UBI file system?

    - Does the kernel configuration (eg. with "make menuconfig") need some special setting for using the firmware?

    - How important are those firmwares after all? Can I just ignore them?

    - I have volumes "boot" and "rootfs" in my UBI fs partiotion "ubifs". It seems attaching the mtd2 now fails. Have I created the UBI fs somehow wrong?

    - Any ideas what might be wrong with the NAND (read-only and cannot mount mtd2)?

    - After loading device tree, boot monitor and kernel from the "boot" volume, should I mount rootfs before running the kernel from the u-boot, since in the "boot" volume I have only 3 binary files: device tree, boot monitor and kernel?

    Best regards,

    Ari

    Hi,
    yes I know the loading has failed. The question is how do I load it into the system so that the kernel finds it? Where it must be located in the UBI fs, in the "boot" or "rootfs" and if there is some additional trick like a configuration setting of the kernel build to make it work.

    And no, I cannot use the prebuilt u-boot and kernel images because this is a custom K2L board with a different HW. There are different DDR3 memory timing settings and the Marvell network phy driver is replaced with TIs PD 83867.

    Best regards, Ari
