CC2642R-Q1: 脱机烧录出现芯片NG

Part Number: CC2642R-Q1
Other Parts Discussed in Thread: UNIFLASH, CC2541, CC2640

我们这边烧录环境为:  轩微脱机烧录器 +  芯片烧录座子 ,近期开始烧录 发现 有大概千分之五~百分之一 的烧录NG现象;

在Uniflash 上面分析烧录NG 芯片:

2021/10/26 上午10:22:53] [INFO] Cortex_M3_0: GEL Output: Memory Map Initialization Complete.
[2021/10/26 上午10:22:55] [ERROR] IcePick_C: Error connecting to the target: (Error -2131 @ 0x0) Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 9.4.0.00129)
烧录座子原理图如下图,  现在不知道哪里出现了问题 ;
