TMS320F28377D: 使用XDS560V2仿真器在Debug时调用FlashAPI程序会在无规律的某一次写入中跑飞 离线运行正常

您好，我们已收到您的问题并升级到英文论坛寻求帮助，如有答复将尽快回复您。谢谢！

您好，

和您确认下，您是说，您目前无法使用 xds560v2来擦除闪存的 N 扇区？ 但能够使用 xds100v3成功擦除扇区？

此外，该程序在没有连接 JTAG 调试探针时工作良好？ 

不是使用xds560擦除是通过程序调用flashapi对内部flash进行读写 但此时debug使用的仿真器是xds560 在外部发sci命令此时下位机程序调用flashapi进行读写的过程中会有很大几率在某一次调用中报错 但当我使用xds100v3进行同样操作时却不会出现报错 下位机程序是运行在BCDEF中 并没有运行在N区

调试状态是通过xds560进行debug 通过串口发送命令给dsp 然后dsp调用flashapi进行数据的擦除和写入 连接仿真器的目的是查看数据是否被正确的写入 但在这个过程中的某一次 ccs就会报错 dsp会直接复位 但在此之前数据都被正确的写入 同样的操作步骤 使用仿真器变为xds100v3进行debug时却不会出现报错复位的情况 此程序离线运行正常

我就没太弄得明白

我们跟进给工程师了，有答复的话尽快给到您。

您好，

那么目前的情况是，在您的程序中有一些内容，以便 F28377D 在通过 SCI 接收到特定命令时执行闪存擦除？

请问您是如何使用闪存 API 的？ 能否分享下该部分代码？（如有不便请联系我，我会通过邮件与您取得联系）

有点长。。.

好的，已跟进给工程师。

您好，

xds100v3和 XDS560V2使用的是单独的软件来生成发送到器件的位。 该问题可能是由 XDS560V2软件中的某些问题引起的，是一个非常具体且很难找到的bug。

对您来说该问题是否很紧迫？还是说可以使用没有该问题的xds100v3继续推进您的项目？

不是非常紧迫 可以继续使用xds100v3继续调试 但是下载的速度较慢 当时采购xda560就是为了调试能够更加快速 如果可以的话希望还是能帮忙找找解决方案 谢谢！

好的明白，我们反馈给工程师看下，应该会在下周工作日给到您答复。
