Some devices that libsigrok can talk to, need a firmware to be uploaded. libsigrok comes with a set of rules to allow non-root users to upload those firmware blobs. Depending on how the system is configured, different set of rules are needed [0] (yes, it's documented on the fx2lafw page, not on the libsigrok one [1]). Basically: - 60-libsigrok.rules is always used; - 61-libsigrok-uaccess.rules is used when systemd-logind is used; - 61-libsigrok-plugdev.rules is used when systemd-logind is not used. For systems without udev, it is the responsibility of the user to implement proper access management if they need non-root to upload firmware files.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
