If the flash chip itself is physically damaged, the bootrom cannot write to it.
The processor is stuck in the very early stage of booting.
Set the to "serialdown" and the Chip Type to "Others" (or your specific model). Perform the Power-On Sequence : If the flash chip itself is physically damaged,
: If using the HiTool software, ensure you have selected the exact chip model (e.g., HI3798MV100). Selecting the wrong chip profile triggers this exact bootrom loop.
: The system's immutable, factory-programmed internal boot sequence is throwing an exception. It cannot hand control over to the primary operating system or secondary bootloader (like U-Boot). Perform the Power-On Sequence : : If using
Users typically encounter this error in several specific situations:
Follow these steps in order to diagnose and fix the connection. 1. Verify the UART Hardware Wiring It cannot hand control over to the primary
BootROM is the first code executed by the CPU. In many STBs (especially Android TV or Google Cast devices), the BootROM includes a “wait for get” mode, where it listens over UART for a specific command or payload from a host PC. The error string suggests the BootROM expected a certain response (possibly the word “google”) but did not receive it.
Physical connection flaws cause the vast majority of serial bootloader drops.
