Previous config had VESC_CAN_TX_GPIO=2 and DISP_BL_GPIO=2 — same pin,
making CAN permanently non-functional. Correct hardware layout (verified in
motor-test-firmware commit 8e66430): SN65HVD230 is on GPIO15/16, display
backlight on GPIO40, display reset on GPIO12.
Also adds IO_UART_TX/RX (GPIO17/18) for future ESP32 IO inter-board link.

The gc9a01 display SPI initialization causes a ~50mA current transient
that trips the brownout detector, causing a boot loop. The bd-66hx power
supply needs decoupling improvement; disabling brownout is the software
workaround until hardware is reworked.
Also discovered the previous sdkconfig was manually corrupted (wrong
partition table, USB JTAG console instead of UART, Memprot lock enabled).
Deleting sdkconfig and regenerating from sdkconfig.defaults restores the
correct OTA partition table, UART0 console, and proper rollback config.

Display was black because gc9a01_init() was never called — driver compiled
but never invoked. Init before vesc_can_init so SPI/register init completes
before TWAI claims GPIO2 (BL pin); TWAI idle=recessive=high keeps BL on.

Without this file, idf.py build fails after fullclean with 'Failed to resolve
component cJSON' because the component manager has no manifest to fetch from.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
CMakeLists.txt REQUIRES 'cJSON' fails on IDF v5.2 — component manager
installs it as 'espressif__cjson'. Update the require name to match.

gc9a01.c and gc9a01.h were never committed to main despite ota_display.c
depending on their display_fill_rect/draw_string/draw_arc functions.
Also:
- CMakeLists.txt: add gc9a01.c to SRCS
- config.h: restore DISP_* GPIO defs (DC=8 CS=9 SCK=10 MOSI=11 RST=14 BL=2)
for Waveshare ESP32-S3-Touch-LCD-1.28
- ota_display.c: fix snprintf buffer too small (verline[32]→[48]) which
GCC 13.2.0 rejects as -Werror=format-truncation
Confirmed builds clean and boots on bd-66hx hardware (mbpi5 /dev/ttyACM0).

Platform is no longer a self-balancing bot. Remove:
- TILT_CUTOFF_DEG (±25° tilt cutoff constant, was unused in ESP32-S3)
- BAL_TILT_FAULT state from bal_state_t enum (no code path generates it)
ESTOP and heartbeat watchdog are unchanged.

Extends the bd-66hx serial protocol with two new Orin→ESP32 commands:
CMD_OTA_CHECK (0x10): triggers gitea_ota_check_now(), responds with
TELEM_VERSION_INFO (0x84) for Balance and IO (current + available ver).
CMD_OTA_UPDATE (0x11): uint8 target (0=balance, 1=io, 2=both) — triggers
uart_ota_trigger() for IO or ota_self_trigger() for Balance.
NACK with ERR_OTA_BUSY or ERR_OTA_NO_UPDATE on failure.
New telemetry: TELEM_OTA_STATUS (0x83, target+state+progress+err),
TELEM_VERSION_INFO (0x84, target+current[16]+available[16]).
Wires OTA stack into app_main: ota_self_health_check on boot,
gitea_ota_init + ota_display_init after peripherals ready.
CMakeLists updated with all OTA component dependencies.

Adds ota_display_task (5 Hz) on GC9A01 240×240 round LCD:
- Idle: orange dot badge at top-right when update available, version text
- Progress: arc sweeping 0→360° around display perimeter with phase label
- States: Downloading/Verifying/Applying/Rebooting (Balance) and
Downloading/Sending/Done (IO via UART)
- Error: red arc + "FAILED RETRY?" prompt
Display primitives (fill_rect, draw_string, draw_arc) are stubs called
from the GC9A01 SPI driver layer (separate driver bead).

Balance side (uart_ota.c): downloads io-firmware.bin from Gitea to RAM,
computes SHA256, then streams to IO over UART1 (GPIO17/18, 460800 baud)
as OTA_BEGIN/OTA_DATA/OTA_END frames with CRC8 + per-chunk ACK/retry (×3).
IO side (uart_ota_recv.c): receives frames, writes to inactive OTA partition
via esp_ota_write, verifies SHA256 on OTA_END, sets boot partition, reboots.
IO board main.c + CMakeLists.txt scaffold included.

Downloads balance-firmware.bin from Gitea release URL to inactive OTA
partition, streams SHA256 verification via mbedTLS, sets boot partition
and reboots. Auto-rollback via CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE if
ota_self_health_check() not called within 30 s of boot. Progress 0-100%
in g_ota_self_progress for display task.

Adds gitea_ota_check_task on Balance board: fetches Gitea releases API
every 30 min and on boot, filters by esp32-balance/ and esp32-io/ tag
prefixes, compares semver against embedded FW version, stores update info
(version string, download URL, SHA256) in g_balance_update / g_io_update.
WiFi credentials read from NVS namespace "wifi"; falls back to compile-time
DEFAULT_WIFI_SSID/PASS if NVS is empty.

Add dual OTA partitions (ota_0/ota_1 × 1.75 MB each) and otadata to
both esp32s3/balance/ and esp32s3/io/ on 4 MB flash layouts.
Enable CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE and OTA HTTP on Balance.
Create esp32s3/io/ project scaffold with config.h pin assignments.

Replaces Orin↔ESP32-S3 BALANCE CAN comms (0x300-0x303 / 0x400-0x401)
with binary serial framing over CH343 USB-CDC at 460800 baud.
Protocol matches bd-wim1 (sl-perception) exactly:
Frame: [0xAA][LEN][TYPE][PAYLOAD][CRC8-SMBUS]
CRC covers LEN+TYPE+PAYLOAD, big-endian multi-byte fields.
Commands (Orin→ESP32): HEARTBEAT/DRIVE/ESTOP/ARM/PID
Telemetry (ESP32→Orin): TELEM_STATUS, TELEM_VESC_LEFT (ID 56),
TELEM_VESC_RIGHT (ID 68), ACK/NACK
VESC CAN TWAI kept for motor control; drive commands from Orin
forwarded to VESCs via SET_RPM. Hardware note: SN65HVD230
rewired from IO43/44 to IO2/IO1 to free IO43/44 for CH343.
