**Stage 1: Setup**
1. Generate a 256-bit HMAC secret key to use for JTAG re-enable.
2. Write the key to an eFuse block with key purpose HMAC_DOWN_ALL (5) or HMAC_DOWN_JTAG (6). This can be done using the ``esp_efuse_write_key()`` function in the firmware or using ``espefuse.py`` from the host.
2. Write the key to an eFuse block with key purpose HMAC_DOWN_ALL (5) or HMAC_DOWN_JTAG (6). This can be done using the ``esp_efuse_write_key()`` function in the firmware or using ``idf.py efuse-burn-key`` from the host.
3. Configure the eFuse key block to be read-protected using the ``esp_efuse_set_read_protect()``, so that software cannot read back the value.
4. Burn the ``soft JTAG disable`` bit/bits on {IDF_TARGET_NAME}. This will permanently disable JTAG unless the correct key value is provided by the software.
