Figure 13-2. Remap Action after Download Completion
The DataFlash Boot program searches for a valid application in the SPI DataFlash memory. If a
valid application is found, this application is loaded into internal SRAM and executed by branch-
ing at address 0x0000_0000 after remap. This application may be the application code or a
second-level bootloader.
All the calls to functions are PC relative and do not use absolute addresses.
The DataFlash Boot software looks for a valid application by analyzing the first 28 bytes corre-
sponding to the ARM exception vectors. These bytes must implement ARM instructions for
either branch or load PC with PC relative addressing.
The sixth vector, at offset 0x14, contains the size of the image to download. The user must
replace this vector with his own vector (see
