刚和TI的技术支持联系,我这个型号的芯片不支持获取版本号命令,听起来有点不可思议,她的回复“I check our user guide and find out G2553 V2.x BSLs doesn’t support get BSL version command.”
我的问题解决了,430G2553还真有个坑啊,因为有密码保护的问题,所以我写数据到flash一直不成功,发送RX_PASSWORD 命令来验证密码,发现不论是什么密码都返回0x90,好坑啊,最后发MASS_ERASE命令整体擦除,把密码置为32个0xFF,然后验证密码,再执行数据写入命令,OK,终于返回0x90了
哥们,你的checksum计算的错了,你试试我这个命令,也是mass erase,和你的命令比,只有checksum不一样,0x80 0x18 0x04 0x04 0x00 0x00 0x06 0xA5 0x7D 0x46
