Arty A7 - Problem running working design from Rev. C

[tomf]

I just bought a second Arty A7-35T board which is a Rev. E board, my first one is a Rev C board. With this Rev C, I successfully generated a design which works fine though the board files are from Rev. E.

Now, I program the new board with the working binaries and if does not work. What can I try to make it work?

你好@TOMF，，，，

1.位文件加载吗？

2.什么类型的设计？IE。微型布莱克还是verilog/vhdl？

3.什么不起作用？IE。完成的LED未完成，USB UART桥未发送信息。

4. Are you able to run the Arty-A7-35T GPIO Demohere？

此致，，，，

Thank you for your help, Jon

1.位文件加载

2.它的微型闪电设计

3. The done LED is lit, neither UART nor Ethernet do work.

4. Flash运行的GPIO演示，也是链接的演示作品。

你好@TOMF，，，，

另一个选择是重新创建项目。这是一个较旧的教程that still works. This sets up a uart ethernet echo server project that should help you re-create your microblaze, uart,ethernet project

此致，

As my project is quite large by now and works on the Rev C hardware, is there no other way to troubleshoot it? Only the Rev E boards makes the problems though the board files are for Rev E...

@TOMF，，，，

我知道Arty A7 Rev的最大差异（@jpeyronmight correct me here) are the flash devices. (There are also different Artix-7 chips now too, so check which one you have.)

您的设计对闪光灯有什么作用吗？您检查过它的配置了吗？

@D@n，，，，

I had a SPI flash implemented in the design, but didnt use it in SDK yet. I tried the following things:

1.从微米到跨度的框图中的SPI块中更改了闪存类型

2.删除SPI块

None of these worked, I still get no response from UART or Ethernet. When I program the Rev. C board with the new bitstream and microblaze binary, it still works.

@TOMF，，，，

还有一些快速的尝试：您是否仔细检查了跳线设置？您是否删除了项目目录，然后为新董事会进行了重建？

否则，我们可能需要返回开始，以验证您可以将某些东西（任何东西）加载到板上：眨眼吗？

担

[tomf]

@D@n，，，，

我已经检查了跳线设置，也已将所有可能的情况放置。我一直安装了Rev E.0的董事会文件，尽管我正在使用Rev. C板，该董事会工作正常。我还需要重建吗？

我加载了示例jpeyron在此处发布，它起作用了。我通过从Flash中运行演示来确认UART的作用。当我在Bitstream上运行简单的Hello World应用程序时，它不起作用。在主循环的第一行中有一个断点显示，验证者从未达到它。当我手动暂停执行时，我会收到一条错误消息：

"Cannot suspend: TCF errror report:

命令：RunControl暂停“ JTAG-JSN-ARTY

[...]

Error text: Cannot stop MicroBlaze. Stalled on instruction fetch

Error code: 1"

@TOMF，，，，

Ok, if I've got this right, the MicroBlaze CPU is trying to start, it makes a request of some peripheral to get its first instruction, and it is unable to do so?

对我来说，这听起来像是一个闪光问题。请记住，闪存设备更改了。与之更改所需的许多配置。较旧的微米闪光灯需要更复杂的设置才能进入。地址之后和数据之前，有不同数量的虚拟周期。闪光灯并非从电源开始启动，也不会重置与较旧的闪光灯相同的重置。

Have you built anything into your design that you can use to query the board and see what's going on? It's typically thefirst thing I build into any of my designs... If you want to try我自己的一些方法，，，，we could take this off-line and work through it.

@TOMF，，，，

另一个快速问题：如果您以SPI X1模式而不是SPI X4（QSPI）模式加载设计，是否有任何改变？

Spansion Flash芯片中有一个内部位，需要在启用QSPI模式之前设置它，因此这可能会有所帮助。Xilinx论坛上的其他人也在努力失去这一点。

担

[tomf]

@D@n，，，，

I tried it with SPI x1 mode which did not work. However, I tried to load the bootloader and application on the flash from SDK. From flash it runs perfectly. I am just unable to run it directy from SDK.

[D@n]

@TOMF，，，，

好的，所以...闪光灯有效，董事会可以工作，但是SDK却没有吗？

这听起来像是SDK的一个文件之一仍然被困在以为您正在使用旧设计，并且根本没有更新。

因此，我要回到@jpeyron's advice and recommend that you rebuild the project, to clean out any undocumented values contained in any Vivado/SDK generated files.

担

[jpeyron]

你好@TOMF，，，，

您是否使用与创建项目相同的Vivado/SDK版本？

此致，

Jon

[tomf]

Yes, it is the same version (2019.1)

Finally solved the problem. It was so easy, but I didnt see it before. The launch button was set to run system debugger on bootloader instead of the firmware.
