Example
boot.bin file check
Figure 11-5. B Opcode
Unconditional instruction: 0xE for bits 31 to 28
Load PC with PC relative addressing instruction:
The sixth vector, at offset 0x14, contains the size of the image to download. The user must
replace this vector with his/her own vector. This information is described below.
Figure 11-6. Structure of the ARM Vector 6
The value has to be smaller than 60 KBytes. 60 KBytes is the maximum size for a valid code.
This size is the internal SRAM size minus the stack size used by the ROM Code at the end of
the internal SRAM.
An example of valid vectors follows:
The NVM bootloader program looks for a boot.bin file in the root directory of a FAT12/16/32 for-
matted NVM Flash.
