win create failing at mcopy #poky #raspberrypi

[-- Attachment #1: Type: text/plain, Size: 5310 bytes --]

I am getting a Codepage 850 error from mcopy when using meta-raspberrypi with the openbmc layers.

What is strange is I had no problems for months, set aside my project, came back and had the failure. The only thing that can be different is my command line actions, or the code pulled from repositories has changed, which in my understanding can't happen.

Before I give details, note that if I use /usr/bin/mtools on the vfat, it succeeds. It is only the mtools from the build that are a problem. Therefore, I concluded that the vfat itself is ok, and the problem is with the tools. Also note I tried older/newer versions of mtools, going back to .18, which is what the base linux OS has and works. But the results are the same. From this I conclude it is not a bug in mtools per se.

There is another thread on this with the context of two docker images, and the result was some missing mtools files. However, I don't have the knowledge of poky and mtools and could not use that hint to actually solve the problem. So if there is something missing in a layer, conf, etc, I need somewhat complete pointers, examples, or learning resources to succeed. Just saying a file is missing is not going to get me far, because I am not a yocto expert yet.

I will break down the info into some categories, and hopefully someone can point me in the right direction:

* SOURCE

-- DETAILS --

SOURCE

openbmc tag 2.8 or 2.9
Adding some layers for device tree and driver patches, but nothing that effects the image

ENVIORNMENT

Ubuntu 14, 16, 18, 20, all have the same results
I use these commands to set the environment and build:

* scripts/install-buildtools
* . poky/buildtools/environment-setup-x86_64-pokysdk-linux
* . oe-init-build-env
* bitbake obmc-phosphor-image

Note that if I build core-image-base I don't have problems. It is in the context of openbmc layers that I have problems. The question may have to be asked on the obmc list, but if so, perhaps someone can help me frame the post to best advantage.

CONF

local.conf has these pertinent settings:

require conf/machine/include/obmc-bsp-common.inc

IMAGE_FSTYPES = "tar.bz2 ext3 wic.bz2 wic.bmap"

The second line prevented obmc image layers from making images incorrectly, as images are normally for ASPEED, not Raspberry Pi. And this worked for months and has not been changed.

MANUAL WIC CREATE RESULTS

I ran wic create manually and get the same result:

I have a little more info on this and a more specific question.

I copied the mtools code and hooked it into the layer so I could put in debug statements.

The problem occurs in charsetConv.c in the function cp_open, when it tries to do an iconv_open using “CP850”, which fails.

I ran “iconv —list” to see what it can convert, and CP850 is not listed.

To prove this is the problem, I hardcoded the iconv_open with “ASCII” and bit bake can go all the way through and “wic create” works properly.

So I ran iconv —version and saw it was “GNU libc 2.31” so I poked around those layers.

Best I can guess is this line from the mtools layer should tell the libc to provide CP850 via this line:

RDEPENDS_${PN}_libc-glibc = "glibc-gconv-ibm850”

Except that that is for runtime, and this is build time.

So I am not sure how glibc decides what converters are used. Is it just a set of defaults? Is there a layer somewhere defining them I could not find?

It seems that somewhere along the way, mtools changed its default to use 850, and it is not compatible anymore.

The solution is probably to tell glibc to provide CP850.

Does anyone know how to do that?

Which version of Yocto Project are you using? Are you using buildtools-tarball 
or uninative in your build?

I suspect you need a newer buildtools-tarball version which includes CP850.

In particular, the CP850 requirement was removed recently:

http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=aaef86ad03d0d7904e42056c5a3e93a960e04ede

I remembered a dependency being added:

http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=268ea5544d204ca35d7709104382bad16705434b

but that was a while ago in 2012 so it seems unlikely you'd be missing the dependency.

The dependency was added to uninative in 2015:

http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=d8d4ce720e5c5823d00c2000d182e0f409240138

I run poky/scripts/install-buildtools with no command line options.

It contains these defaults:

DEFAULT_INSTALL_DIR = os.path.join(os.path.split(scripts_path)[0],'buildtools')
DEFAULT_BASE_URL = 'http://downloads.yoctoproject.org/releases/yocto'
DEFAULT_RELEASE = 'yocto-3.2_M3'
DEFAULT_INSTALLER_VERSION = '3.1+snapshot'
DEFAULT_BUILDDATE = '20200923'

I see I can use command line options to use a different release if you have guidance on what to use.
