有块开发板烧写了固件，希望读回存档，请问有方法吗？PhoenixSuit似乎只有单向的烧写能力。

sample_region 范例报错，同一张板sample_virvi2venc2muxer都可以运行。另外每次运行以后TF卡就变readonly

回复: sample_vi2venc2muxer 在V851S上崩溃发布在 V853系列-AI视觉
@strugglingprogrammer 还是不行。换V853使用tina-v853-docker SDK编译也是一样的，是不是tina-open的源码库上加mpp模块的不是官网建议的？

大佬好啊，这个gdb提供的信息不太够啊，我从V851s换V853了，为了避免内存不足。但是还是一样的效果。开发板用的100ask的
