|
* @brief APP 运行期 SPI 命令从机模块。
|
|
|
|
|
|
*
|
|
|
|
|
|
* 复用 BOOT 的 SpiOta 协议帧格式（SOF+TYPE+LEN+PAYLOAD+CRC）：
|
|
|
|
|
|
* - TYPE=0xB0 → 请求进入 Bootloader，回复 ACK 帧
|
|
|
|
|
|
* - TYPE=0x01/0x02/0x03（OTA 命令）→ 回复 WAIT 帧（不在 BOOT 模式）
|
|
|
|
|
|
* - 旧式单字节 0xB0 命令仍兼容
|
|
|
|
|
|
*
|
|
|
|
|
|
* 调试日志采用延迟输出：processCommand() 只写缓冲+置标志，
|
|
|
|
|
|
* poll() 中再 printf，避免在帧处理路径上耗时。
|

|

|
|
*
|
|
|
|
|
|
* 发送路径使用 DMA0_CH2 推 s_txBuf → SPI0_DATA，
|
|
|
|
|
|
* 与 BOOT 的 SpiOta 实现保持一致；接收仍用 RBNE 字节中断。
