cairo.Error: input string not valid UTF-8

[vick]

I am working on bootchart.png.

When I use command "bootchart bootchart.tgz", it shows up this error:

Thanks for help.

Hi Vick,

Interesting. I you attach your "bootchart.tgz" then I'll have a look.

Best,
Anders

[Riccardo Magliocchetti (riccardo)]

vick, do you have a reference to what the nvs parameter is supposed to contain?

[vick (cvcv62075)]

Hi Riccardo,

Which file have nvs parameter?

Thanks.

[Riccardo Magliocchetti (riccardo)]

Vick, it's a parameter you are passing to your kernel. If you open the tarball you can see it in the file named header.

[vick (cvcv62075)]

Hi Riccardo,

I am working on embedded system, so I can only see the nvs parameter by tarball ?

[Riccardo Magliocchetti (riccardo)]

It's the stuff you are presumably passing to the kernel from the bootloader. cat /proc/cmdline from the tegra board will show you what i'm talking about.

[vick (cvcv62075)]

It shows up
nvs=����������������������������������������������������������������������������;��������������������������������������������������������������������;��������������������������������������������;������������������������

Anders, i think i'm ending up with something like this in bootchart2, what do you think?

[Anders Norgaard (anders-norgaard)]

Looks sensible.

Best,
Anders

Hi Riccardo,

My source code didn't match your patch, how can I use this patch ?

Now, I still have this bug, please give me some help!

Thanks!

[Riccardo Magliocchetti (riccardo)]

Vick, somebody from ubuntu should change the patch to apply or fix it in another way.

[vick (cvcv62075)]

My ubuntu version is 11.04.

So the reason is caused by ubuntu system ? not the source(bootchart.tgz)
created by the embedded system ?
