Compal board numbers follow the LA pattern with project code and P suffix printed on the PCB, alongside a revision marking. The size matches a 64 Mbit SPI flash. Use an SPI programmer to restore corrupted firmware, verifying the board number first and saving the existing chip contents before erasing and writing.
