引脚接触检查通过!
ID: 0x EF 70 18 ......OK!
擦除 ...完成,  耗时...0.406 秒
解保护完成
写入FLASH ...完成,  耗时...72296ms
校验FLASH ...
错误! FLASH地址: 0x000000  缓冲区值: 0x1C  芯片数据: 0xFF
写入 ...失败


请教下这是被写保护了吧?这个芯片还有办法解除掉写保护吗?

    As a user,                   Learning new thing is challenging . In the case of this IC, i can see in version
12.60 of Xgecu software, and based in the image you post, that all 3 security registers LB1, LB2 or LB3, are set to 1,
then OTP (one time programming) seem activated and present in the IC.
AS i never worked with this one, but found that you have two entries a normal IC and an OTP version
version of the IC, that shows an 'ERASE OTP ' selection in the 'options' tab at bottom .
Reading the datasheet isn't conclusive for me if the OTP set can be fully reverted or not.

Hope it helps

完全被锁死了,不能改写的,买个新片替换
