[Avila] GW2348-4 with corrupt Flash, cannot erase

[Chris Lang]

Brian,

Is this problem only when you are trying to erase this specific block, or is at other locations in the flash? 

I would be suprised if it had something to do with the expansion bus timings as these timing issues would typically show themselves upon reading/programming not erasing.

Also, why are you trying to erase just a portion of the rootfs partition? What happens if you just execute "fis erase rootfs"? 
Where you ever able to execute "fis init -f"?

  I have a GW2348-4 that I've been using for development and testing for a couple weeks, and I am no longer able to entirely erase Flash.  It is running the original RedBoot 2.04 that came with it (never jtagged), and I just can't erase the block at 0x50d60000 without the call hanging (using fis delete, erase or init -f, and trying unlock beforehand).  Like I said, its only a couple weeks old, so I don't think there's any way I'm running into worn out blocks.  It seems like my best bet is to get my hands on a jtagger and try RedBoot 2.02, before Flash accesses were "optimized".  I'm just wondering if anyone else has seen this and has any suggestions.
