: The "c31" prefix typically denotes a versioning scheme, a hardware platform identifier, or a specific cryptographic context. In many proprietary firmware distributions (e.g., from manufacturers like Broadcom, MediaTek, or Allwinner), "c31" might refer to:
: Disable secure boot via fuses (dangerous) or use the manufacturer's official signed images. c31bootbin verified
= a boot image for the TMS320C31 DSP that has passed structural integrity checks (header, checksum, address bounds, endianness). It ensures reliable power‑up program loading from an external EPROM or host. Verification is critical in embedded systems where no JTAG or debugger is available to recover from a bad boot image. : The "c31" prefix typically denotes a versioning
