cc3220sf 使用uniflash无法连接

Other Parts Discussed in Thread: UNIFLASH, CC2640R2F, CC3220SF

1. 在拿到手以后使用CCS导入例程并成功debug,但每次复位或断电以后代码都会刷回到out_of_box例程,(怀疑是代码未写入FLASH,仅在RAM中)

2. 在学习MQTT例程时需要烧写网络证书,我按照TI给的步骤使用uniflash进行烧写,但其无法连接,一直在打转(已经升级过uniflash 也已经断电重试)

3. 我更换了CC2640R2F连接uniflash,成功连接(排除电脑问题)

4. 我现在该怎么办?1的现象是不是证明开发板已经异常?还是说需要设置才能将代码烧写进flash?

谢谢各位!
