Apr 21, 2017 · In the flash there is a custom bootloader (@0x8000000) that will performs some basic operations, then it will jump at a specified address (e.g. 0x8030000). The source code of custom bootloader is not accessible. The generation of the elf file is successful and the map file seems correct (also using objdump).

During MCU startup, entry point is 0x08000000 (Boot sector), boot firmware validate the CRC32 of sector C to perform upgrade if available, then validate sector B (User application) to jump for main program operation. CRC32 validation During startup, boot loader will calculate CRC32 of sector C and B from offset 0x00000000 to offset 0x0003FFFB.

Jun 01, 2012 · The core masks off the least significant bit of an address and uses it to detremine the instruction set it is running in. So to jump to a bootloader address and stay in thumb mode, you must add 1 to the destination address. On the larger ARM parts this allows you to jump in and out of thumb mode when doing function calls. From Page 59

You have to look it up yourself in the source code of the start up code (I am not familiar with the requested CPU -- but I have written custom bootloaders for other Renesas CPUs, and for those the answer is yes). If the vector table is fixed, then you have to implement it relocatable yourself in the bootloader. Edit.

8 Linker Description - Texas Instruments
8.4.23 C Language Options (--ram_model and --rom_model Options) The --ram_model and --rom_model options cause the linker to use linking conventions that are required by the C compiler. The --ram_model option tells the linker to initialize variables at load time. The --rom_model option tells the linker to autoinitialize variables at run time.

As it's never changed in the field, this isn't really on. For example, we never call the boot-loader directly: the only route into it is through the reset vector.
