Unbricking of VOXL2 is failing (build failure)

pettertei

Hi,

I lost my device after getting it to work for a while, and thought that the issue was that my device got bricked.

I was following your unbricking tutorial and ran into following error (not encountered in the previous unbricking threads 1, 2, 3, 4, 5, 6)

I think I got the Provisioning and Flash CDT done with some warnings (also weirdly the green text says that things succeeded even if things failed)

I have the QRB5165M version and I was using the Latest: VOXL 2 QDL Image 14.1a_1.7.8. I am usinf Ubuntu 22.04 and like said, the Starling 2 was working for a while and established a connection there, but then I lost it.

Any ideas why the flashing fails?

Hi @pettertei,

Can you run the following command inside the flat build folder?:

sudo qdl --debug --storage ufs --include . prog_firehose_ddr.elf rawprogram_unsparse0.xml rawprogram1.xml rawprogram2.xml rawprogram3.xml rawprogram4.xml rawprogram5.xml patch0.xml patch1.xml patch2.xml patch3.xml patch4.xml patch5.xml

This will flash the flat build manually and give a more verbose output as to why you're experiencing issues with the flat build flash

@Nathan-Raras said in Unbricking of VOXL2 is failing (build failure):

sudo qdl --debug --storage ufs --include . prog_firehose_ddr.elf rawprogram_unsparse0.xml rawprogram1.xml rawprogram2.xml rawprogram3.xml rawprogram4.xml rawprogram5.xml patch0.xml patch1.xml patch2.xml patch3.xml patch4.xml patch5.xml

Thanks for the reply @Nathan-Raras

It gives me the following error:

I/O warning : failed to load external entity "rawprogram_unsparse0.xml"
[PATCH] failed to parse rawprogram_unsparse0.xml
qdl: failed to detect file type of rawprogram_unsparse0.xml

I have the rawprogram_unsparse0.xml there in the ufs

And, I am using USB-C -> USB-A via USB-C hub to my Dell XPS 13 if that makes any difference?

And on my Ubuntu, the install_dependencies.sh did not install the qdl to /usr/local/bin, thus calling it from the "local" modules folder.

Nathan Raras

Hi @pettertei,

It's possible that there's an issue with the XML parser where it tried to open or failed to find the rawprogram_unsparse0.xml file.

Can you ensure libxml2 is installed by running:

dpkg -l | grep libxml2

If not present, run the following to install:

sudo apt install libxml2

pettertei

@Nathan-Raras It seems that the libxml2 is up-to-date

Hi @Nathan-Raras et al.

Do you have any ideas what could be going on, or is the only remaining option to send the device back to you for a "factory reset"?

@pettertei I'd recommend filing an RMA and we can debug the issue: https://www.modalai.com/pages/rma
