在配置UCB(user configured block)时,将CONFIRMATION的数据0x43211234错误地写在了偏移为0x01F4的地址上(实际地址应位于0x01F0)。目前的现象是,板子复位灯常亮,无法连接仿真器。有大佬遇到过这种问题吗?芯片锁死这种情况是不是一定要更换芯片才能解决了?

目前看来好像只能换芯片了,仔细研究了下手册里的SSW(startup software),发现UCB Orign和Copy都有问题的话确实会陷入开机启动死循环的状态....

用UDE再次刷写UCB,加载后跳出Programming对话框,进入DF_UCBS ,将enable勾上,点击Program All刷写,试一下。

谢老哥回答,现在用的是劳德巴赫T32和英飞凌的memtool,都连不上。只要是连上了就好说,刷个好用的UCB 就行啦~

如果里面有boot loader的话,可以试试用boot loader去更新UCB解锁
