   @stbenn the terminology used in flash devices can indeed be confusing. The 
term block is especially confusing, I would advice against using it (the same 
for page). The most clear definition I have found up to now are:
   * Erase-block: the smallest size to erase, this is sometimes also referred 
to as sector.
   * Write-block: the smallest size to write, this is used by bwrite,
   * Page: the largest size that can be written in one operation, typically for 
external flash that have a page buffer.
   
   The most important thing is not to interprète the block used in bwrite as 
being the same block used in erase.
