to an address specified by the application. When the bootloader receives the G
it transmits the ACK byte to the application. After sending the ACK byte, the bootloader waits
for an address (4 bytes, where Byte 1 is the address MSB and Byte 4 is LSB) and a
checksum byte, then it checks the received address. If the address is valid and the
checksum is correct, the bootloader transmits an ACK byte; otherwise, it transmits a NACK
byte and aborts the command.
When the address is valid and the checksum is correct, the bootloader firmware performs
the following:
●
●
●
For example, if the received address is 0x0800 0000, the bootloader will jump to the
memory location programmed at address 0x0800 0004.
In general, the host should send the base address where the application to jump to is
programmed.

It initializes the registers of the peripherals used by the bootloader to their default reset
values.
It initializes the user application's main stack pointer.
It jumps to the memory location programmed in the received ‘address + 4’ (which
corresponds to the address of the application's reset handler).
