TMS320C5515: CSL_USB_MSC_dmaExample例程下载到开发板上无法运行

您好，已经收到了您的案例，调查需要些时间，感谢您的耐心等待。

您好，

     对TMS320C5515支持有限。

     请参考链接帖子讨论的内容是否有帮助。

我按照这个方法试了一下，但我还是没有成功。我的代码如下：

void HWI_unused(void)
{
/* minimal ISR stub: return immediately */
asm(" NOP");
return;
}
void early_hardware_and_interrupt_init(void)
{
/* 1) Configure ICR (address 0x0001) and execute IDLE to make configuration take effect */
*(volatile ioport Uint16 *)0x0001 = 0x020E;
asm(" idle");

/* 2) Register HWI using BIOS API (Hwi_create). This preserves dispatcher behavior
* equivalent to useDispatcher=1 in the .tcf configuration.
*/
{

/* Use DSP/BIOS HWI API to plug handlers and set per-HWI attributes
* to match the .tcf configuration (ier0/ier1 masks).
*/
HWI_Attrs attrs;

/* INT5 (vector 5) : mmcsd0_isr, IER0 mask 0x0020 */
attrs = HWI_ATTRS;
attrs.ier0mask = 0x0020;
attrs.ier1mask = 0x0000;
HWI_dispatchPlug(5, (Fxn)mmcsd0_isr, &attrs);

/* INT7 (vector 7) : mmcsd0_isr, IER0 mask 0x0080 */
attrs = HWI_ATTRS;
attrs.ier0mask = 0x0080;
attrs.ier1mask = 0x0000;
HWI_dispatchPlug(7, (Fxn)mmcsd0_isr, &attrs);

/* INT8 (vector 8) : dma_isr, IER0 mask 0x0100 */
attrs = HWI_ATTRS;
attrs.ier0mask = 0x0100;
attrs.ier1mask = 0x0000;
HWI_dispatchPlug(8, (Fxn)dma_isr, &attrs);

/* INT9 (vector 9) : mmcsd0_isr, IER0 mask 0x0020 */
attrs = HWI_ATTRS;
attrs.ier0mask = 0x0020;
attrs.ier1mask = 0x0000;
HWI_dispatchPlug(9, (Fxn)mmcsd0_isr, &attrs);

/* INT12: unused stub (keep default attrs) */
attrs = HWI_ATTRS;
HWI_dispatchPlug(12, (Fxn)HWI_unused, &attrs);

/* INT20 (vector 20) : USB ISR, IER1 mask 0x0010 */
attrs = HWI_ATTRS;
attrs.ier0mask = 0x0000;
attrs.ier1mask = 0x0010;
HWI_dispatchPlug(20, (Fxn)USBisr, &attrs);

}
/* 3) Clear IFR groups (clear pending flags) */
CSL_CPU_REGS->IFR1 = 0x0;

/* 4) Enable required IER bits (example: enable USB CPU interrupt) */
CSL_FINST(CSL_CPU_REGS->IER1, CPU_IER1_RCV3, ENABLE);
CSL_FINST(CSL_CPU_REGS->IER1, CPU_IER1_XMT3, ENABLE);
CSL_FINST(CSL_CPU_REGS->IER1, CPU_IER1_USB, ENABLE);

/* Note: enable additional IER bits for MMC/SD/DMA if required.
* If using BIOS, consider using BIOS HWI_create instead of direct vector writes.
*/
}我把他们封装进了一个函数里，并在main.c的开头使用。
我对tcf文件做了一些更改：
1.删除掉了TSK_MUSBMainTask 和 TSK_MUSBMSCTask 任务创建，因为我想动态创建usb任务。

2.按照上述帖子中的更改方式，注释掉了中断的设置。因此结果如下：

main函数开头如下所示：。我还是没有成功，您能帮我看看该如何配置吗？

您好，    

    建议您测试一下 SPRC133 驱动程序或库 | 德州仪器 TI.com.cn最新版本中的示例。

e2echina.ti.com/.../evm5515-csl_usb_msc_dmaexample_out-bin 我按照整个链接中的帖子进行尝试，代码如下：

void early_hardware_and_interrupt_init(void)
{

/* 2) Register HWI using BIOS API (Hwi_create). This preserves dispatcher behavior
* equivalent to useDispatcher=1 in the .tcf configuration.
*/
{
// /* Use DSP/BIOS HWI API to plug handlers and set per-HWI attributes
// * to match the .tcf configuration (ier0/ier1 masks).
// */
HWI_Attrs attrs;
//
// /* INT5 (vector 5) : mmcsd0_isr, IER0 mask 0x0020 */
// attrs = HWI_ATTRS;
// attrs.ier0mask = 0x0020;
// attrs.ier1mask = 0x0000;
// HWI_dispatchPlug(5, (Fxn)mmcsd0_isr, &attrs);
//
// /* INT7 (vector 7) : mmcsd0_isr, IER0 mask 0x0080 */
// attrs = HWI_ATTRS;
// attrs.ier0mask = 0x0080;
// attrs.ier1mask = 0x0000;
// HWI_dispatchPlug(7, (Fxn)mmcsd0_isr, &attrs);
//
// /* INT8 (vector 8) : dma_isr, IER0 mask 0x0100 */

// HWI_dispatchPlug(9, (Fxn)mmcsd0_isr, &attrs);
//
// /* INT12: unused stub (keep default attrs) */
// attrs = HWI_ATTRS;
// HWI_dispatchPlug(12, (Fxn)HWI_unused, &attrs);
//
/* INT20 (vector 20) : USB ISR, IER1 mask 0x0010 */
attrs = HWI_ATTRS;
attrs.ier0mask = 0x0000;
attrs.ier1mask = 0x0010;
HWI_dispatchPlug(20, (Fxn)USBisr, &attrs);
/* Map MMCSD/PROG events to mmcsd0_isr */
IRQ_plug(PROG0_EVENT, mmcsd0_isr);
IRQ_plug(PROG1_EVENT, mmcsd0_isr);
IRQ_plug(PROG2_EVENT, mmcsd0_isr);

/* Map DMA event to dma_isr (if used) */
IRQ_plug(DMA_EVENT, dma_isr);

// /* Map USB event to USBisr */
// IRQ_plug(USB_EVENT, USBisr);

/* Clear any pending flags for these events (safe to do here) */
IRQ_clear(PROG0_EVENT);
IRQ_clear(PROG1_EVENT);
IRQ_clear(PROG2_EVENT);
IRQ_clear(DMA_EVENT);
// IRQ_clear(USB_EVENT);

}
// /* 3) Clear IFR groups (clear pending flags) */
// CSL_CPU_REGS->IFR1 = 0x0;

}
在CSL_Status configDmaforMmcSd(void)  函数中使能了dma。



main函数如下：



用hex55生成bin文件以及下载方式如下所示：

但是依然没有启动成功，

下载成功后，重新上电重启，代码无任何运行，指示灯也不灭。

另外 usb中断的使能方式不知道为啥不能用// IRQ_plug(USB_EVENT, USBisr);
// IRQ_clear(USB_EVENT);
// IRQ_enable(USB_EVENT); 这几个函数使能，我用他们使能debug调试无法启动usb，总是显示设备无法识别，只有用
HWI_Attrs attrs;
attrs = HWI_ATTRS;
attrs.ier0mask = 0x0000;
attrs.ier1mask = 0x0010;
HWI_dispatchPlug(20, (Fxn)USBisr, &attrs);这种方式，才能使pc识别usb并打开文件，这是什么原因？

可否有这方面的专家帮我解答一下问题？
