电路板在测试的过程中,发现如下问题:
1、当电路板上,boot电路的拨码开关打到从FLASH启动程序模式时(GPIO72和GPIO84都拉高),通过XDS200给板子下载程序,总是报下图的错误。(但是,当boot电路在72和84都拉高的时候,使用100V3仿真器下载,是可以成功下载的)

2、当我将GPIO72拉高,GPIO84拉低时,通过XDS200下载程序到电路板,是成功的(但是,偶尔也会出现以下两种情况,第一种是low-power模式,第二种是先报Error -6311的错误,但是可以将程序下载进电路板中)


3、当把程序烧写到电路板中,单步运行的时候,出现下面的两种报错,打断单步运行。
第一种报错:
C28xx_CPU1: Error: (Error -1044 @ 0x0) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 9.2.0.00002)
C28xx_CPU1: Error: (Error -1135 @ 0x82B3F) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 9.2.0.00002)
C28xx_CPU1: Unable to determine target status after 20 attempts
C28xx_CPU1: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
第二种报错:

思考了和修改了许久,一直没办法解决。
特来请教,谢谢!
期待您的回复!
