The Bootrom uses an auto-baud detection mechanism or relies on a hardcoded frequency. If the desktop flashing tool transmits too fast or too slow, synchronization fails.

The flashing tool is pointing to the wrong hardware port.

If your STB firmware is deeply corrupted, the bootloader might be stuck in an infinite crash loop, completely ignoring the UART port. You can force the processor to fallback to the BootROM by temporarily shorting the data pins on the flash memory chip.
