关于 option 字段
请问下,关于stm32 option bytesfile:///C:\Users\xu\AppData\Roaming\Tencent\Users\290507124\QQ\WinTemp\RichOle\)MGDN`8T6Y@TXF(%98@W17K.pngThe option bytes are used to write-protect the memory (with 4 KB granularity) and/or
readout-protect the whole memory with the following options:
– Level 0: no readout protection
– Level 1: memory readout protection, the Flash memory cannot be read from or
written to if either debug features are connected or boot in RAM is selected
– Level 2: chip readout protection, debug features (Cortex®-M0 serial wire) and
boot in RAM selection disabled
中,Level 1与Level 2 的区别。
Level 2 打开后,如果修改程序,flash还能擦除吗?
我没试过,不过听说Level2打开后,这个芯片就相当于固定了,没法再写程序了!!! MrJiu 发表于 2017-7-7 13:55
