DSP2812解锁问题还有串口SCI烧写问题 跪求TI工程师解决

Other Parts Discussed in Thread: ISO3082

试用串口SCI烧写flash程序,没有成功,但是看到SDflash官网有如下说法SDFlash and Prog28x v1.65 update to support device unlock after reset. Prog28x includes source code. Replace your current CCSv4 or CCSv5 SDFlash directory with the update. The F28xx algorithms will enable unlocking as by setting the PMSTAddress field to non-zero value.意思是不是可以解锁我已经加密的DSP,

还有就是如何硬件设计才能实现485烧写程序,或者用USB转232(或者485)模块烧写程序,我板子上用的iso3082来实现485隔离通讯
