It sounds like you’re encountering a low-level boot failure on an embedded system (likely a Rockchip or similar ARM-based SoC), where the mask ROM (BROM) is being disabled due to an eFuse configuration. The code 0x146 typically points to a security or fuse-related policy that prevents further booting.

6. When All Else Fails

  • Check vendor documentation: Search for “BROM error 0x146” + your SoC model in the vendor’s TRM (Technical Reference Manual).
  • Community help: Rockchip forums, Linux-rockchip mailing list, or Armbian forum users may have board-specific eFuse bypass methods (e.g., clock glitching – advanced, rarely possible).
  • Replace the board/chip: For mass-produced locked devices, the device is effectively bricked for unsigned code.

The 0x146 efuse is a hardware-level security lock. The best and most reliable solution is almost always the Test Point method. It physically overrides the security check, giving you full access to the chip for flashing, unlocking, or repair.
