LPC54628 Linker

[lua40927]

I am using the official KEIL library

My question is the starting position of the HEX file generated by KEIL will not change

I set as below picture

123.png

The answer I got with google is to tick like the picture below

789.png

But this will give the following error

456.png

The .S file of LPC54628 is as shown below

999.png

Not the same as the .S file I found

What should I do?

Thanks

Hi

The download code starting address is defined by linker file *.scf. 

Is LPC54628J512_Flash.scf your project linker file or bootloader.scf?

Please edit the text starting address to define the code starting address. make sure the code size is not changed or not over the Flash allowed size.

Have a nice day,

Thanks for your help.

I have found the scf file,

Some of the contents are as follows.

#define m_interrupts_start 0x00000000
#define m_interrupts_size 0x00000400

#define m_text_start 0x00000400
#define m_text_size 0x0007FC00

#define m_data_start 0x20000000
#define m_data_size 0x00028000

what is the difference between these three(interrupts,text,data)
