# Offline checksum tool

This folder keeps the original XC6517 offline burn helper used only to calculate
the checksum segment for release file names.

Normal release flow:

1. Build the Keil project and generate `mdk\ble_peripheral.bin`.
2. Run `tools\make_release_bin.ps1` from the repository root.
3. The script copies `ble_peripheral.bin` to `download.bin`, runs
   `Xinc_mac_tool.exe`, extracts the checksum from the generated offline file
   name, then copies the real online burn file to `release\online`.

Do not use the generated offline BIN as the online burn file.
