From fb047a6a54ffd872a4059d04a3f2a8b59ae9ab29 Mon Sep 17 00:00:00 2001 From: Carl-Daniel Hailfinger Date: Fri, 16 May 2008 21:11:53 +0000 Subject: I looked at the datasheet and erase_sector_39sf020() is totally and completely wrong. It was a straight cut'n'paste from SST 28SF040 code and the person doing the cut'n'paste didn't even bother to check the data sheet. The SST 39SF020 is completely incompatible with the 28SF040. No need for replacement. According to the data sheet, standard JEDEC commands will work and we have those commands in the tree already.
