The update to firmware version (F30104) has introduced a critical regression that causes the LR1121 to enter an unrecoverable "Logic Lock" state during initialization. This is not a hardware failure or a wiring issue; it is a fundamental flaw in how the firmware manages its internal state machine upon reset.
The firmware has changed the internal validation sequence required to exit the bootloader and enter "Standby" mode. In previous versions , the chip followed a "safe-to-talk" protocol that allowed the host MCU to establish SPI communication immediately after a reset. However, the f30104 update has introduced a strict internal gate that prevents the chip from transitioning to a responsive state.
