QSPI加载器在CubeProgrammer中读取函数失败是何原因

问答对人有帮助，内容完整，我也想知道答案 0 你好。我用 W25Q64 为 STM32F746NEH6 开发了一个定制板。我为这个闪存芯片制作了一个驱动程序。一切（如读取、写入、擦除、内存映射模式...）工作正常... 但是在制作 stldr 文件后我得到了这个错误：这是我的引出线：读取函数是否导致此错误？但是loader不需要这个功能。我测试了内存映射模式功能......它工作正常......在其他代码中使用它后，外部闪存作为内部闪存工作： uint8_t CSP_QSPI_EnableMemoryMappedMode(void) { QSPI_CommandTypeDef sCommand = {0}; QSPI_MemoryMappedTypeDef sMemMappedCfg; /* basic configuration / sCommand.InstructionMode = QSPI_INSTRUCTION_1_LINE; // 1 line mode Send instruction * / sCommand.AddressSize = QSPI_ADDRESS_24_BITS; // * 24 Bit address * / sCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE; // * No interverter byte * / sCommand.DdrMode = QSPI_DDR_MODE_DISABLE; // * W25Q64JV does not support DDR * / sCommand.DdrHoldHalfCycle = QSPI_DDR_HHC_ANALOG_DELAY; // * DDR mode, data output delay * / sCommand.SIOOMode = QSPI_SIOO_INST_EVERY_CMD; // * Each transmission must send instructions * / // * Read data * / sCommand.Instruction = QUAD_OUT_FAST_READ_CMD; // * Read status command * / sCommand.AddressMode = QSPI_ADDRESS_1_LINE; // * 1 Line address * / sCommand.DataMode = QSPI_DATA_4_LINES; // * 1 wire data * / sCommand.DummyCycles = 8; // * 8 cycles * / //MemoryMapped settings sMemMappedCfg.TimeOutActivation = QSPI_TIMEOUT_COUNTER_DISABLE; sMemMappedCfg.TimeOutPeriod = 0; if (HAL_QSPI_MemoryMapped(&hqspi, &sCommand, &sMemMappedCfg) != HAL_OK) { return HAL_ERROR; } /* basic configuration / sCommand.InstructionMode = QSPI_INSTRUCTION_1_LINE; // 1 line mode Send instruction * / sCommand.AddressSize = QSPI_ADDRESS_24_BITS; // * 24 Bit address * / sCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_4_LINES; // * 4 Line interverter byte * / sCommand.AlternateBytesSize = QSPI_ALTERNATE_BYTES_8_BITS; // * 1 Byte alternate * / sCommand.AlternateBytes = 0xFF; // * should be 0xFx * / sCommand.DdrMode = QSPI_DDR_MODE_DISABLE; // * W25Q64JV does not support DDR * / sCommand.DdrHoldHalfCycle = QSPI_DDR_HHC_ANALOG_DELAY; // * DDR mode, data output delay * / sCommand.SIOOMode = QSPI_SIOO_INST_EVERY_CMD; // * Each transmission must send instructions * / // * Read data * / sCommand.Instruction = QUAD_INOUT_FAST_READ_CMD; // * Read status command * / sCommand.AddressMode = QSPI_ADDRESS_4_LINES; // * 4 Line address address * / sCommand.DataMode = QSPI_DATA_4_LINES; // * 1 wire data * / sCommand.DummyCycles = 4; // * 4 cycles * / //MemoryMapped settings sMemMappedCfg.TimeOutActivation = QSPI_TIMEOUT_COUNTER_DISABLE; sMemMappedCfg.TimeOutPeriod = 0; if (HAL_QSPI_MemoryMapped(&hqspi, &sCommand, &sMemMappedCfg) != HAL_OK) { return HAL_ERROR; } } 所以...有什么问题？谁能帮助我吗？ 0

答案对人有帮助，有参考价值 0 我评论了内存映射函数的第一部分，在第二部分中使用了 2 个虚拟周期而不是备用 0xff 字节： uint8_t CSP_QSPI_EnableMemoryMappedMode(void) { QSPI_CommandTypeDef sCommand = {0}; QSPI_MemoryMappedTypeDef sMemMappedCfg; // /* basic configuration / // sCommand.InstructionMode = QSPI_INSTRUCTION_1_LINE; // 1 line mode Send instruction * / // sCommand.AddressSize = QSPI_ADDRESS_24_BITS; // * 24 Bit address * / // sCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE; // * No interverter byte * / // sCommand.DdrMode = QSPI_DDR_MODE_DISABLE; // * W25Q64JV does not support DDR * / // sCommand.DdrHoldHalfCycle = QSPI_DDR_HHC_ANALOG_DELAY; // * DDR mode, data output delay * / // sCommand.SIOOMode = QSPI_SIOO_INST_EVERY_CMD; // * Each transmission must send instructions * / // // // * Read data * / // sCommand.Instruction = 0x6B; // * Read status command * / // sCommand.AddressMode = QSPI_ADDRESS_1_LINE; // * 1 Line address * / // sCommand.DataMode = QSPI_DATA_4_LINES; // * 1 wire data * / // sCommand.DummyCycles = 8; // * 8 cycles * / // // //MemoryMapped settings // sMemMappedCfg.TimeOutActivation = QSPI_TIMEOUT_COUNTER_DISABLE; // sMemMappedCfg.TimeOutPeriod = 0; // // if (HAL_QSPI_MemoryMapped(&hqspi, &sCommand, &sMemMappedCfg) != HAL_OK) { // return HAL_ERROR; // } /* basic configuration / sCommand.InstructionMode = QSPI_INSTRUCTION_1_LINE; // 1 line mode Send instruction * / sCommand.AddressSize = QSPI_ADDRESS_24_BITS; // * 24 Bit address * / sCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE; // * 4 Line interverter byte * / //sCommand.AlternateBytesSize = QSPI_ALTERNATE_BYTES_8_BITS; // * 1 Byte alternate * / //sCommand.AlternateBytes = 0xFF; // * should be 0xFx * / sCommand.DdrMode = QSPI_DDR_MODE_DISABLE; // * W25Q64JV does not support DDR * / sCommand.DdrHoldHalfCycle = QSPI_DDR_HHC_ANALOG_DELAY; // * DDR mode, data output delay * / sCommand.SIOOMode = QSPI_SIOO_INST_EVERY_CMD; // * Each transmission must send instructions * / // * Read data * / sCommand.Instruction = 0xEB; // * Read status command * / sCommand.AddressMode = QSPI_ADDRESS_4_LINES; // * 4 Line address address * / sCommand.DataMode = QSPI_DATA_4_LINES; // * 1 wire data * / sCommand.DummyCycles = 6; // * 4 cycles * / //MemoryMapped settings sMemMappedCfg.TimeOutActivation = QSPI_TIMEOUT_COUNTER_DISABLE; sMemMappedCfg.TimeOutPeriod = 0; if (HAL_QSPI_MemoryMapped(&hqspi, &sCommand, &sMemMappedCfg) != HAL_OK) { return HAL_ERROR; } return HAL_OK; } 然后评论了 CSP_QUADSPI_Init 函数中的配置 func 部分......终于成功了！在配置中，我将 QE 位设置为“高”（对于 jv 系列，它默认为高）并将 DRV0/DRV1 设置为“00”……但实际上这是问题的原因！
