Why does the material stm32f205rey6 have no ST logo. Do the following 7522 and 8032 refer to Datecode? If it represents the date, wha

生产几K套时�?�现大部分 datedote 7522 和 8032 使用了ST-link 或J-link 使用SWD方�?�?能烧录连接 ，开始以为是SWD功能被�?用了，试了�?�?和 boot0拉高�?��?行,使用Jtag方�?也�?行。带用ST logo�?�?�的�?�是OK的，请问这两�?方�?什么�?�?��?�？还是什么特殊烧录设置�?�？

During the test, it was found that most datedote 7522 and 8032 used st link or j-link, and they could not burn the connection by using SWD mode. At first, I thought that the SWD function was disabled. After trying reset and boot0 pull up, they couldn't do it, nor could they use JTAG mode. What is the difference between the two ways? Or any special burn settings

Only bottom right parts looks genuine. Expect clones or even fakes.

Hi all the components are genuine . It's just a different place of production
