This often means the firmware is for a slightly different hardware revision (e.g., a different Wi-Fi chip like the XR829 vs. AW859A). allwinner a133 firmware work

Getting the DDR (DRAM) to initialize correctly is often the hardest part of porting firmware to a new board. The A133 is usually paired with LPDDR3 or LPDDR4. The firmware contains a binary blob—the DRAM parameters—that tells the memory controller how to talk to the RAM chips. If these timings are off, the device crashes instantly, often without a flicker on the screen. The A133 is usually paired with LPDDR3 or LPDDR4

or a Secondary Program Loader (SPL) into the internal SRAM. This stage is responsible for the most basic hardware setup, specifically initializing the DRAM (system memory) so that larger programs can be loaded.
