TESTING: M3 / M7 / M8 ✅ verified 2026-06-14

Hardware bring-up of the Hosyond panel, FT5426 touch, and local
screens are all confirmed working on the Waveshare ESP32-P4-ETH.

Also retire the resolved hardware unknowns (DSI pin count, I²C pins,
BOOT button) — they're answered in the body now.

M4 / M5 / M6 still need ethernet + a curl-driven run to flip.

+Hardware unknowns — resolved:
 
-1. **DSI FPC pin count on the Waveshare board.** Research found 2-lane MIPI-DSI confirmed; pin count not verified. Open the schematic PDF and count.
-2. **I²C jumper destinations.** `display.c` defaults `PIN_I2C_SDA=7`, `PIN_I2C_SCL=8` — matches Waveshare's BSP convention for their bundled panel kit but not specifically verified for this board. Confirm against schematic; adjust `display.c` if wrong.
-3. **BOOT button GPIO.** ESP32-P4's strap pin (GPIO 35) is owned by RMII TXD1 at runtime, so the on-board user/BOOT button must be on a different GPIO. `button.c` currently uses `PIN_BOOT_BUTTON = 0` as a placeholder. Confirm from schematic; if wrong, the button silently never fires but the rest of M8 still works.
+1. **DSI FPC pin count on the Waveshare board.** ✅ 22-pin DSI on board; bridge to the panel's 15-pin Pi FPC via a 15→22 adapter cable.
+2. **I²C jumper destinations.** ✅ `PIN_I2C_SDA=7`, `PIN_I2C_SCL=8` confirmed by ATTINY ack at 0x45 + FT5426 ack at 0x38.
+3. **BOOT button GPIO.** ✅ No usable GPIO — ESP32-P4 GPIO 35 strap pin is owned by EMAC TXD1 at runtime; no separate user button is wired on the Waveshare ESP32-P4-ETH. Both BOOT behaviours moved onto touch long-press (≥1.5 s → identity overlay) and very-long-press (≥5 s → factory reset).
 4. **Flash size silkscreen.** `sdkconfig.defaults` declares 16 MB. If your SKU shipped with 32 MB the build still works but you waste half the flash.
