SDK的flash_demo擦写正常，下面是demo中擦写执行代码
- uint32_t FlashCommandSequence (PFLASH_SSD_CONFIG pSSDConfig )
- {
- uint32_t ret; /* return code variable */
- uint32_t temp; /* temporary variable */
- /* clear CCIF to launch command */
- temp = pSSDConfig->ftfxRegBase + FTFx_SSD_FSTAT_OFFSET;
- REG_BIT_SET(temp, FTFx_SSD_FSTAT_CCIF);
- /* wait for completion of this command */
- temp = pSSDConfig->ftfxRegBase + FTFx_SSD_FSTAT_OFFSET;
- while(0x0U == (REG_BIT_GET(temp, FTFx_SSD_FSTAT_CCIF)))
- {
- /* wait till CCIF bit is set */
- /* serve callback function if counter reaches limitation */
- if(NULL_CALLBACK != pSSDConfig->CallBack)
- {
- (pSSDConfig->CallBack)();
- }
- }
- temp = pSSDConfig->ftfxRegBase + FTFx_SSD_FSTAT_OFFSET;
- ret = ((uint32_t)(REG_READ(temp)) & FTFx_SSD_FSTAT_ERROR_BITS);
- return(ret);
- }
REG_BIT_SET(temp, FTFx_SSD_FSTAT_CCIF);这句话执行完擦写操作就生效了
我把demo里的代码移植到我的code中去，flash相关的寄存器值一样子的，只是运行完这句话并不会完成擦写操作。
有没有其他原因使flash无法擦写？
