周边信息太少很难预估问题方向啊

W600 建议先用 V3.3 版本,底层 flash 驱动经测试发现,写入时中途掉电,还存在扇区数据全部丢失的问题,可能与 xip 的 cache 有关。所以 V4.0 可能暂时在 W600 片上 flash 上存在问题,后续我再跟原厂深入确认下吧。

是的,昨天测试W600时EasyFlash V4.0又出现了EF_ASSERT(0)
错误,经查是跳入了//TODO 扇区连续模式,或者写入长度没有写入完整
块里了,应该就是数据没写完。
V3.3经过12小时测试倒是没有问题。此外,另一块M4架构的芯片用V4.0进行同样的测试也没有问题。
W600的flash驱动确实有点问题。
到此结贴了,W600官方SDKv3.2.0下就用EasyFlash V3.3就行了。
