cannot find entry symbol Reset_Handler; defaulting to 08000000
Hi,
This is a link time error.
“Reset_Handler” symbol should be defined in MCU startup file (written in assembler). Check if you have one file named “startup_stm32f030xx.s” (I think this should be the name in you case).
The place where to look for this file is “/startup” directory from where the “.project” is located (this is the project directory) - so go to project directory and then try to locate this file in startup dir.
In the project explorer check if you have a directory named startup.
In startup file you should have a section like this:
.section .text.Reset_Handler
.weak Reset_Handler
.type Reset_Handler, %function
Reset_Handler:
ldr r0, =_estack
mov sp, r0 /* set stack pointer */
and later in the same file
g_pfnVectors:
.word _estack
.word Reset_Handler
Regarding the address 08000000 - this is the start address for Flash memory, at this address after a Reset, microcontroller start to execute code instructions.
The GNU linker (ld.exe) informs you that will put the code starting with this address.
