Together they uniquely identify a firmware binary and its intended hardware/market. Firmware updates are crucial for enhancing the performance,

Firmware updates are crucial for enhancing the performance, security, and functionality of devices. These updates can: a minimal bootstrap remains intact.

A: Yes, if you have physical access and the chip is not read-protected. Use an SPI programmer (like CH341A) to dump the flash. Then you can clone it to another board.

The bk suffix is particularly interesting. In firmware naming conventions, .bk typically indicates a recovery-capable build—meaning even if the primary flash fails, a minimal bootstrap remains intact. This suggests the manufacturer prioritized failsafe updates over raw speed.
