## Summary
The RTL8721Dx / RTL8720F ports packed the flashable application as
`app.bin`
and also dropped several intermediate images (per-core `*_image2_all.bin`,
`ota_all.bin`) plus `boot.bin` into the top-level build directory, and the
`make flash` target relied on a fixed image directory. This reworks that to
match the common NuttX convention and to be robust against flash-layout
changes:
- The packed application image is now named `nuttx.bin` and is the only
image
left in the top-level build directory (alongside the map files). The
prebuilt bootloader `boot.bin` stays in the board `prebuilt/` directory.
The
redundant per-core and OTA image copies are no longer copied to the top.
- `make flash` reads the boot and application flash offsets from the SDK
flash
(`CONFIG_FLASH_BOOT_OFFSET` / `CONFIG_FLASH_[APP_]OTA1_OFFSET`) and
writes
`boot.bin` and `nuttx.bin` each at its own offset, so a layout change is
tracked automatically and no offset is hardcoded.
- Board documentation updated accordingly.
## Impact
- Users: the flashable image is `nuttx.bin` (was `app.bin`); the top-level
build dir is cleaner. `make flash` is unchanged in usage
(`make flash AMEBA_PORT=/dev/ttyUSB0`).
- Build: affects only `boards/arm/rtl8721dx`, `boards/arm/rtl8720f` and
their
shared `arch/arm/src/{rtl8721dx,rtl8720f}` build glue. No other
arch/board.
- Hardware / runtime: no change to the firmware itself.
- Documentation: RTL8721Dx / RTL8720F board pages updated.
## Testing
**Build host:** Ubuntu 22.04 (x86_64, WSL2), GCC 11 for host tools; target
toolchain: Realtek `arm-none-eabi` asdk (auto-fetched).
**Targets:** `pke8721daf:nsh` (RTL8721Dx), `rtl8720f_evb:nsh` (RTL8720F).
Both boards built, flashed and booted (NSH + Wi-Fi STA).
Top-level artifacts after `make` (after change):
$ ls *.bin nuttx
nuttx nuttx.bin
$ ls boards/arm/rtl8721dx/pke8721daf/prebuilt/boot.bin
boards/arm/rtl8721dx/pke8721daf/prebuilt/boot.bin
`make flash` (offsets read from the generated layout):
FLASH: .../prebuilt/boot.bin @ 0x08000000
FLASH: .../nuttx.bin @ 0x08014000
Device boots to NSH and connects to Wi-Fi after flashing.
