When facing an issue on a unique hardware configuration on the end user side it may prove useful to submit system logs to Dasharo team for diagnosis and possibly problem solution. This section describes how to dump various logs from a running system.
One may use Dasharo Tools Suite HCL report or fwdump-docker image to gather all the hardware configuration information from a running system. The usage of the tools should result in an archive containing various logs from the running system. Submit them via email to firstname.lastname@example.org or use Dasharo pastebin.
When already migrated to Dasharo, it is possible to retrieve firmware logs from
coreboot on a running system. A utility called
cbmem can be used for that
purpose. By obtaining the logs Dasharo team will be able to locate any issues
with the firmware. This method requires Secure Boot to be disabled.
