[PATCH] add support for flash writes not starting at offset 0 #12

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I'm doing some fancy image generation and flashing; effectively using three 
firmware images (a "bootloader" and two "firmware" images) that need to be 
flashed (and more importantly, erased) independently.  

The attached patch adds support for specifying a page offset into the flash, 
for reads, erases, and writes.  

The patch also fixes an off-by-one error in the erase function -- the byte 
after the erase command is "number of pages -1" ie a value of 12 means that 13 
pages will be erased. (see pg 21 of ST's AN3155 "USART Protocol used in the 
STM32 bootloader" rev 2)
