Error in opening firmware binary file for i.mx6 solo wandboard

[lonsn]

Hi,

I have an i.mx6 solo wandboard and I am testing the video decode function.

Kernel is 3.0.35 from wandboard and rootfs is rootfs.tar.bz2 from freescale L3.0.35_3.0.0_121207_images_MX6.tar.gz.

I failed for following test and seems error in opening vpu firmware binary.

But actually I have firmware file:

root@freescale /$ ls -l /lib/firmware/vpu/

From vpu/vpu_util.c:

I see that it get wrong cpu info, for wandboard solo:

Processor       : ARMv7 Processor rev 10 (v7l)

processor       : 0

BogoMIPS        : 790.52

Features        : swp half fastmult vfp edsp neon vfpv3

CPU implementer : 0x41

CPU architecture: 7

CPU variant     : 0x2

CPU part        : 0xc09

CPU revision    : 10

Hardware        : Wandboard

Revision        : 62011

Serial          : 0000000000000000

So the CPU id is 0x62, but in vpu_util.c, it only detect 0x63(imx6q) and 0x61(imx6dl).

What's the problem? Is it a vpu lib error or kernel error?

[lonsn]

It's because the CPU id is 0x62 in mainline u-boot, but in vpu lib, it still detects 0x63 or 0x61.

[fabio_estevam]

Can you try a quick test: in the Wandboard board file, please name it "Freescale Wandboard".

I saw some cases that the VPU plugins was looking for a hardcoded "Freescale" string. I though this issue was already fixed, but if not, let me know.

Also, please try to use the latest BSP for the mx6solo.

[lonsn]

I have done the test, Since VPU plugins look for the board revision number from /proc/cpuinfo and it only accepts 0x63,0x61. After I change the system_rev to 0x61011 in the kernel, VPU decode is OK now.

[fabio_estevam]

Thanks for testing. Which U-boot version do you use for Wandboard?

I added support for this one:

git.denx.de Git - u-boot/u-boot-imx.git/commitdiff

and the original one is this:

u-boot (2009.08): Add support for Wandboard-Dual ·  954c7b1 · Freescale/meta-fsl-arm-extra · GitHub

Do they differ in the returned value for the board revision?

Please let me know so that I can fix it.

[lonsn]

I have used the first one.

git.denx.de Git - u-boot/u-boot-imx.git/commitdiff.

I didn't test the u-boot(2009.8) version.

But for the default u-boot image provided from wandboard website, the hardware revision in proc/cpuinfo is OK.

[fabio_estevam]

Could you please apply this patch http://pastebin.com/JHdY2nkD ?

Please let me know if it fixes the VPU issue on the Wandboard.

Thanks,

Fabio Estevam

Ok, I tested on my Wandboard solo and now I see that it returns 0x61011 with this patch applied:

http://marc.info/?l=u-boot&m=136430248207678&q=raw

I sent it to the U-boot list. Hopefully it will work for you as well.

[lonsn]

Yes, I have tested your patch. It works. Thanks a lot.

[fabio_estevam]

Ok, I understand the problem now.

Will submit a patch tomorrow to fix it.

Thanks,

Fabio Estevam
