AWR1443: AWR1443 Chip does not work

Hi,

I bought some AWR1443 chips, but they don't work on my own PCB. I used 6 pieces of AWR1443 chips, five of which can download code using Uniflash, but the system did not work, as shown in Fig. 1. The download codes is:

C:\ti\mmwave_industrial_toolbox_4_7_0\labs\vital_signs\14xx_vital_signs\pjt\Prebuilt_binaries\xwr14xx_vitalSigns_lab_mss.bin，

the other chip cannot download the code, as shown in Figure 2.

About a month ago, I also bought some 1443 chips from another company, and they worked fine on the same PCB.

Are there any quality problems with those chips?

如果可以的话，做一下交叉实验，看一下是不是芯片本身的问题。如果是芯片的问题，从TI授权代理商那里购买的话，请联系您的购买渠道。如果是从TI网上购买的，请提供订单号，需要转给相关部门处理。
