正常连接DSP后,下载程序时显示:
C28xx_CPU1: GEL Output:
Memory Map Initialization Complete
C28xx_CPU1: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.
C28xx_CPU1: File Loader: Verification failed: Values at address 0x80000@Program do not match Please verify target memory and memory map.
C28xx_CPU1: GEL: File: C:\Users\Administrator\Desktop\P5_CPU1_V116.87.out: a data verification error occurred, file load failed.
目前的情况是这样的,新加工的一批控制板,都是这个问题。若换成之前的控制板(BOM相同),同样的CCS程序和其他配置等完全相同,能够正常下载。
不清楚什么原因。

两款芯片只是晶圆厂和批次不同,芯片版本是相同的C版本
很抱歉,目前我们没有提供丝印查询服务
根据您的实验现象描述的话,应该是您芯片本身的问题,因为硬件是完全相同的
建议您将问题芯片连接uniflash试一下,看是否可以正常烧写
