Hi,
So I Want to make custom board library for my board as is for the lpcxpresso(lpc1549).
So I made a copy of the original project and replaced my pins as appropriate in board_sysinit.c.
But after that i noticed that in my project file which is using the new library its Board_Init function is not doing anything, whatever is put in it. How must be declared this function and called in order to work? Am i missing something in the porting process for custom board.
Regards,
Boyko

#1 Copy a working board lib.
#2 Change it. Don't forget to change board name.

/* Board name */
#define BOARD_NXP_LPCXPRESSO_1549

in board.h

#3 Build Debug & Release version
#4 Change Includes/Libraries of your project or use Smart Update

That's all.

Your application needs to call Board_Init() and likely SystemCoreClockUpdate() before that. Board_Init() is not called as part of SystemInit().

int main(void)
{
/* initialize the board */
SystemCoreClockUpdate();
Board_Init();
Board_LED_Set(0, false);

I cannot find why any function from board.c cannot be accessed from my main.c I double checked the board library is included and the include folder. I check that changes in board_sysinit.c work but on board.c ( same location) doesn't.

You don't acutally explain what the problem is - for example, are you getting compile/link errors, or is the function not being called?
Please post a project that exhibits this problem, and we will investigate to see what you have done wrong.

Non of the functions from board.c are called, its like the file dont exist. Is there specific place in my current project settings to say that when i Include board.h the function body is in board.c
also what is the purpose of board_api?

:quest:

Is there a Board_Init() in your main? Is it executed?

Hi R2,
yes there is but it doesn't execute. when i press F3 it opens the body in board.c but when it is called in main none of it content happens.

What does that mean?

Setting a breakpoint there and stepping forward is doing what?
