Detection of Flash Erase Sector Size?

benstickrod — Fri, 10 Mar 2006 01:42:53 GMT

Is there any way to tell, in code, if the sector erase size of a part is 512 or 1024 bytes? I know of at least one part in the B family that has a 1024 sector erase size and I need my bootloader to be compatible with 512 or 1024 byte parts.

Thanks,

Ben

You mean like a 'flash ID byte"? I don't think there's a function for that.

But can't you ID the cpu? I thought that was unique to each configuration, or am I wrong...

I can ID the micro, but I would need a list of micros that have 1024 byte sector sizes. I was looking for something that I could use to tell what the size of the flash sector was without knowing what micro was being used.

Thanks,

Ben,

The only way to keep this sector size is to make a table, which is not very efficient. Best bet is to use #defines and configure the sector size in the pre-compile stage.
