DCA1000EVM: DCA1000 FPGA_RST亮红灯， 网口连不上。

使用Diamond Programmer重新烧入FPGA bit，问题依然无法解决。 请问能提供返修服务吗？

我的这个板子是在mouser上购买的， 估计TI不支持返修，比较遗憾。

电源适配器5V，3A。 同一个电源适配器在另外一个DCA1000 试了，没有问题。

这个板子比较贵， 坏了确实挺让人心疼的。

FPGA固件为C:/ti/mmwave_studio_03_00_00_14/mmWaveStudio/PlatformBinaries/DCA1000FPGA/DCA1000_FPGA_RECORD_V2.8_05JUL2019.bit版本，下载过程没有问题。

您好，已为您咨询工程师，这需要一些时间，谢谢！

好的， 如果能返修就更好了。

您好，以下是工程师的回复：

Thanks for the post. You may want to double check your switch positions against the user manual, in case you have moved them. (see Figure 16 specifically, which is different than what you have selected) The re-programming procedure is in this manual, too. https://www.ti.com/lit/ug/spruij4a/spruij4a.pdf

If you are still having issues and have reconnected the Ethernet cable, reconnected the RADAR EVM to the DCA, and double checked that your static IP is set up on your PC, etc. Please do provide some sharper images of your setup as well as any screen shots you can take of where the failure is occurring. 

我把问题描述整理到这个word文件中了， 请帮忙看看内容是否足够~

您好，以下是工程师的回复：

thanks for the document. Only difference i can see here is the choice on the SPI flash device. 

in the manual it says to choose this on (in the dropdown):  SPI-N25Q128A (page 25)

Can you try that out and double check your switch settings, as well, if you are changing them. 

Hi  Gary,

I use Diamond Programmer 3.11

there is no “SPI-N25Q128A” in the device list.   I think "N25Q128A" is equivelent to  “SPI-N25Q128A”~

您好，已跟进

您好，以下是工程师的回复：

In looking at the schematic, if the FPGA is being held in reset only FPGA and the switch SW7 are connected to control the red LED you have on - something physical may have happened to the FPGA on your board. Are you using in ESD safe or protected environment?

我们平常使用并没有特别注意ESD问题。能返修吗？ 在mouser上购买的， mouser不支持返修。这个板子挺贵的。
