1. 0x33 0000 ① 0x33 8000 ② ① ② 0x33 FFF6 ① ② ① ② Sector B Sector A
Main.c
(hex FILE)
Main.app will be moved to sector B
By second Bootloader.c 0x ① 0x
Sector A ②
Main.c
(hex FILE)
Second bootloader’s Role:
Receive main.app through UART and save to on sector B when I need to update main.c
2. After power on, branch to the sector B in order to give control to main.app
Second Bootloader.c ① ②
0x33 FFF6
Boot to Flash Entry Point ① ②
Power on
Question 1: How can I give control of device from second bootloader.c to main.c?
just use asm(“LB 0x ”)(sector B hard address) in bootloader.c?
Question 2: How can second bootloader.c distinguish between procedure of updating main.c and giveing control to main.c immediately. ① ②
