Part Number:LAUNCHXL-F280049COther Parts Discussed in Thread:UNIFLASH
Error connecting to the target:
(Error -1015 @ 0x0)
Device is not responding to the request. Device may be locked, or the debug probe connection may be unreliable. Unlock the device if possible (e.g. use wait in reset mode, and power-cycle the board). If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 9.3.0.00058)
这是板子被锁了吗?

Error connecting to the target:(Error -1041 @ 0x0)The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation.(Emulation package 9.3.0.00058)
有时候还会出现这个问题
,
Susan Yang:
This can be caused by several sources of errors: a problem in the FTDI chip, bad I/O pins on the debug probe, issues on the circuit between the FTDI chip and the JTAG header, or a problem with the target device.
您是官网购买的板子?可以先换一根线试试
或者可以使用该开发板上的仿真器烧录其他芯片、开发板看是否正常
或者使用其他板子或独立仿真器烧录该开发板的芯片试试,看是否正常

user6492660:
你好,我的开发板是从代理商买的,这个是板载仿真器,我不明白您是什么意思,我的仿真器连接测试如下

Susan Yang:
请确认是否使用的下面的配置
,
Susan Yang:
“仿真器连接测试是可以的,就是程序烧不进去”
请问您是CCS烧录还是uniflash烧录?
烧不进去的话,请问具体错误是什么?
,
user6492660:
是CCS烧录,本来程序是可以正常运行的,突然有一次不知道什么原因,出现以下错误,之后就一直这样了
,
Susan Yang:
如错误消息中所建议,请使用“Wait in reset mode”(或Wait BOOT)为设备加电,如果问题与“LOCK”有关,您应该能够连接到JTAG。
连接后,请使用 CCS 内存监视窗口检查 Flash 中密码位置的值(地址请参考 TRM)。如果您看到所有内容都为 0x0,则设备确实处于锁定状态。
,
user6492660:
你好,依然是在下载过程中出现上面的错误提示,看不CCS内存监视窗口
,
user6492660:
你好,我刚刚测了硬件,发现VVD是1.9V供电,这个是哪里错误?正常是1.2V吧
,
Susan Yang:
您使用了 wait boot模式进行测试?是否可以成功连接uniflash来查看内存?
user6492660 说:发现VVD是1.9V供电,这个是哪里错误?正常是1.2V吧
是的,正常是1.2V
,
user6492660:
您上面的两种方式均尝试失败,我估计是因为VVD 1.9V的原因,现在还没想为什么会有这个问题
,
Susan Yang:
根据您的描述,硬件上出现问题的概率比较大。是否可以成功连接uniflash来查看内存?
,
user6492660:
不能连接成功,如果是硬件问题,您觉得大概率会是哪一部分的原因
,
Susan Yang:
那在电脑的设备管理器中是否有显示?
,
user6492660:
有的
,
Susan Yang:
不能连接成功uniflash的错误提示是什么?我今天拿板子看一下
,
user6492660:
错误提示如下,我记得开发板之前烧录程序时,LED2是不会一直亮的,现在会了,还有用手触摸U6芯片引脚时,LED4和LED5也会突然发亮
,
Susan Yang:
user6492660 说:LED2是不会一直亮的,
是的,LED2不会一直亮
user6492660 说:还有用手触摸U6芯片引脚时,LED4和LED5也会突然发亮
我的开发板上也是这样的
请参考下面的链接来操作
https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/489852/c28xx-error-connecting-to-the-target-error–1015-0x0/1768334#1768334
若还是不能成功的话,请您使用外部仿真器来连接一下该launchpad看是否可以成功连接
,
user6492660:
本来LED2是不会亮的,但是一旦debug就会一直亮
,
Susan Yang:
请问您现在情况怎样了?
,
user6492660:
还是没想到问题的原因,我暂时也没测试
,
Susan Yang:
好的,还是等您测试后我们再讨论
