Assuming that you have GnuBee PC1 without any upgraded firmware nor installed linux distribution you have two choices using the built-in webserver or using a USB-stick.
The GnuBee PC 1 has a 32MB soldered on Flash-chip. It contains 6 parts. Their names (u-boot, u-boot-env, factory,firmware,kernel,rootfs,rootfs_data) should be self-explanatory.
Upgrading the firmware as documented here, will replace the content of the firmware,kernel,rootfs and rootfs_data.
All the firmware discussed here, have the following common characteristics:
- The mount a read/write overlay partition, where changes are preserverd over reoboots. This allows you to add more packages, download scripts, change password, etc.
- By default there is no root password.
- After the startup you may access the device ** either with a USB-to-UART cable as

Download a firmware (Check whether there are newer files present). Depending on what you want to achieve you choose:

Copy firmware to USB-Stick (MS-DOS format)
Use a USB-stick with a MSDOS partition table and a vfat or fat partition. Copy the downloaded file and rename it to gnubee.bin. Unmount the USB-stick.
Flash the firmware
Place your USB-stick into any of the 3 USB connectors. Reboot the GnuBee via a SW command or by pressing twice the red power on/off button.
While loading the new firmware the LEDs will give an indication or reading/writing. Lower LED fast blink = read, slow blink = write, solid = done. (This may take several minutes.) When the upper LED changes from off to on solid it’s time to remove the USB Stick and reboot into the new firmware.
