#179170 - Small boot sectors at start or end of flash Responding to: ???'s previous message |
The size of the sectors.
A flash with uniform flash sectors have the same size for all flash sectors. A flash with boot sector design, have a number of smaller sectors at start or end of flash, depending on if the flash is intended for a processor that boots from address 0, or a processor that boots from the top addresses. An example - a flash with uniform sector sizes may have 128kB sector sizes. A flash with boot sectors, may have a number of 4kB sectors at one end, and then the rest of the sectors are large 128kB sectors. With some small sectors, you can write a tiny boot loader, or at least store the interrupt vectors and a jump to somewhere else in the flash. |
