[参考译文] TMS320F28388D：如何读取/写入内部闪存？

Meili、

您是否已经尝试了 C2000Ware 中提供的闪存编程示例？

谢谢、此致、

当然、但我找到的所有示例都是针对外部存储器和 CPU1的。

我能知道内部存储器示例的位置吗？

我使用 C2000Ware_3_04_00_00。

能否使用'i2c_ex2_EEPROM"项目测试内部闪存写入？

我尝试过、但函数 I2C_isBusy 返回 ERROR_BUS_BUSY。(第23行~26)

//
// writeData - Function to send the data that is to be written to the EEPROM
//
uint16_t
writeData(struct I2CMsg *msg)
{
    uint16_t i;

    //
    // Wait until the STP bit is cleared from any previous master
    // communication. Clearing of this bit by the module is delayed until after
    // the SCD bit is set. If this bit is not checked prior to initiating a new
    // message, the I2C could get confused.
    //
    if(I2C_getStopConditionStatus(I2CA_BASE))
    {
        return(ERROR_STOP_NOT_READY);
    }

    //
    // Check if bus busy
    //
    if(I2C_isBusBusy(I2CA_BASE)) // <--An error occurs here!
    {
        return(ERROR_BUS_BUSY);
    }

    //
    // Setup number of bytes to send msgBuffer and address
    //
    I2C_setDataCount(I2CA_BASE, (msg->numBytes + 2));

    //
    // Setup data to send
    //
    I2C_putData(I2CA_BASE, msg->memoryHighAddr);
    I2C_putData(I2CA_BASE, msg->memoryLowAddr);

    for (i = 0; i < msg->numBytes; i++)
    {
        I2C_putData(I2CA_BASE, msg->msgBuffer[i]);
    }

    //
    // Send start as master transmitter
    //
    I2C_setConfig(I2CA_BASE, I2C_MASTER_SEND_MODE);
    I2C_sendStartCondition(I2CA_BASE);
    I2C_sendStopCondition(I2CA_BASE);

    return(SUCCESS);
}
