m:Robe 500 hangs on bootscreen

[cereal_killer]

I have a m:Robe 500 with OF version 1.03 and I followed the instructions on the wiki using the well tested method. When Rockbox launches it hangs on the boot screen:

Code: [Select]

Rockbox boot loader
Version r20941 :20942M-090516
ATA
disk
mount
Loading firmware
Lenght: E446C
Checksum: 578D8F5
Model name: m500
Loading rockbox.mrobe500
Sum: 578D8F5
Only a reset helps.
How can I start Rockbox?

What version of Rockbox are you running? The m:Robe is one of our more neglected targets, so it's quite possible that we've inadvertently broken it since whoever last tested it.

I downloaded a dev build some days ago: version 84624e14f8-200415

So you mean it is a problem of the Rockbox build not of the bootloader? I will try to reinstall and use a recent build.

I reinstalled everything from scratch using the latest dev build. Same result, but with slightly different text on the screen.

Code: [Select]

When I install the modified firmware using the Windows updater, the information on the screen of my PC says version 1.05, but when checking the version on the m:Robe it says 1.03. Is this intended?

My next step is to find out the latest working build. Can I do this with bisect? https://www.rockbox.org/wiki/UsingGit#How_do_I_bisect_using_git_63

Does anyone have a working build for this player and would share it with me? That would be nice.

You should definitely be able to bisect, but I think your first step should be figuring out whether the problem is in the bootloader itself or the rockbox image.

If it is the bootloader, then I am at my wit's end. But I thougt start with trying a build that is known to work.

I found the first commit that prevents rockbox booting on the m:Robe. Here ist the bisect output:

    Put -lfirmware in CORE_LIBS, to fix -thumb builds
   
    For unknown reasons, -thumb builds need -lfirmware after -lrbcodec (but
    still before -lunwarminder)i. Other builds are still happy if we do that.
    Including it via CORE_LIBS instead of explicitly achieves that.

I had a look at the diffs, but this is way over my head. How could this be fixed?

Because of speachys comment on IRC I tried builds before and after this commit to see if they were working or not working:
Revision 8bd992c works and revision 3e2b50e doesn't work.

It seems, that this might be related to the toolchain, see discussion on IRC
