The firmware programs NXP LPC1549 micro-controller on GL300c RC Main board. Earlier GL300 models had NXP LPC1765 instead, which has separate m1400 firmware.
TODO
There are multiple versions, always unencrypted.

All the published versions are without encryption.
The unencrypted firmware is a memory image of ARM binary. During startup, it is being loaded into memory at address 0x0a000 (unverified) and executed by a loader. Such memory images are usually prepared by first linking the file with all libraries, and then using objcopy -O binary to get the final file without ELF header. The ELF header can be re-created if the address and boundaries of sections are known.
No analysis of the booting procedure were performed.
The image is based on FreeRTOS.
No signatures of common libraries were found in the code.
