The verification mechanism described is not theoretical. It is deployed in:
On a BR23 chip that runs a full Linux system (e.g., some advanced soundboxes), enabling Verified Boot prevents unauthorised or corrupted firmware from being executed. A message like br23uboot100 verified could indicate that the bootloader has completed its signature verification and successfully handed control to the next stage.
If you want to check a signature manually from the command line, U-Boot includes a built-in test that can be used to simulate and verify the entire signing process. You can use the fdt command to inspect the device tree and check that the public key was embedded correctly. br23uboot100 verified
Knowing the device (e.g., a car head unit, an IoT device, or a specific control module) will help me find the exact "verified" post or documentation you need.
For developers using the JieLi SDK (e.g., ac695n_soundbox_sdk ), the UBOOT1.00 mode is essential for testing new builds. The SDK provides a batch script download.bat that invokes isd_download.exe with the correct parameters. You can edit this script to change flash layout or enable debugging options.
Stripping out unneeded legacy drivers and utilizing highly optimized compiler flags allows the verified bootloader to pass control to the operating system in milliseconds, a vital requirement for critical systems. : Hold the Power button for 10–20 seconds

When any of these verification steps fail—or when the chip’s internal bootloader is erased or corrupted—the device may drop directly into mode. This is a fallback state where the chip awaits a new firmware image over USB. From the user’s perspective, it appears as a non‑functional brick, but in reality the chip is waiting for a proper flash operation.
