我有一个 S32K144 设备,其中程序分区命令 (PGMPART) 用于分配 keysize = 1 到 20 的 CSEc。
但是没有安装 MASTER_ECU_KEY。这意味着没有执行 CMD_LOAD_KEY。 之后使用 JLink 调试器和 Erase 命令发出批量擦除 现在调试器无法连接并显示以下内容: 剧透 (Highlight to read)SEGGER J-Link Commander V7.80d (Compiled Oct 4 2022 16:40:45) DLL version V7.80d, compiled Oct 4 2022 16:40:22 Connecting to J-Link via USB...O.K.
