F28M35H52C: f021 flash擦除问题

Part Number: F28M35H52C
Other Parts Discussed in Thread: CONTROLSUITE

大家好:

    问个Flash擦除有关的问题。

    我做了段M3核程序prog.bin(C2000没有启动),程序功能是擦除所有flash,然后通过网络重新下载prog.bin,然后后重新烧回flash。现在遇到以下问题:

  1.连接仿真器(xds560v2)运行程序,然后下载,擦除,重新写入都正常完成(通过memory browser观察),完成后的数据也导出来与prog.bin比对过,没有区别。然后在CCS 6.2 DEBUG界面下用reset和restart按钮进行复位,重复下载重新烧写功能失败,打断点发现Fapi_issueAsyncCommandWithAddress运行返回成功,但是对应的区域并未擦除成功。

2.下载程序后直接断电拔仿真器运行,芯片也是擦除失败。怀疑也是Fapi_issueAsyncCommandWithAddress执行问题。

请问大家是否遇到过
