请教下, 利用在 V7 里面的 u盘历程升级hal库或者 usb库后,貌似识别不到u盘,有谁遇到过吗 ?
v7 里面的 usb 库版本是:
* @version V3.2.2
* @date 07-July-2015
hal 库版本:
/**
* @brief STM32H7xx HAL Driver version number V1.3.0
*/
#define __STM32H7xx_HAL_VERSION_MAIN (0x01) /*!< [31:24] main version */
#define __STM32H7xx_HAL_VERSION_SUB1 (0x03) /*!< [23:16] sub1 version */
#define __STM32H7xx_HAL_VERSION_SUB2 (0x00) /*!< [15:8] sub2 version */
#define __STM32H7xx_HAL_VERSION_RC (0x00) /*!< [7:0] release candidate */
#define __STM32H7xx_HAL_VERSION ((__STM32H7xx_HAL_VERSION_MAIN << 24)\
|(__STM32H7xx_HAL_VERSION_SUB1 << 16)\
|(__STM32H7xx_HAL_VERSION_SUB2 << 8 )\
|(__STM32H7xx_HAL_VERSION_RC))
这个 v1.3.0 hal 驱动库版本升级到 v1.5.0, usb 库保持不变的话, 读写u盘都正常,
但是 把上述任一 一个库 版本升级 就都不行了, 比如把
hal 升级到 1.6.0 或者
usb 库升级到 /**

再或者 hal 库与 usb 都同时升级,结果都不行 ??????????
应用部分都保持不变, 程序编译都是没有发生任何警告与错误提示
