📝 Walkthrough

Walkthrough

The flasher updates stub firmware metadata and encoded payloads for multiple ESP32 variants. It adds ESP32-H4 and ESP32-P4 rev1 definitions, updates ESP32-S3 NAND plugin data, and routes older ESP32-P4 revisions to the new rev1 stub.

Poem

A rabbit checks the stubs at dawn
New bytes hop where old ones yawn
H4 joins the flashing trail
P4 rev1 sets its sail
NAND maps receive their tune
Every chip gets code anew
