Can't link bmp file

michaelhuslig — Fri, 09 Dec 2016 22:59:38 GMT

I used the following ld code successfully on an earlier K22 project to link in the binary of a bootloader.

/********************************************/

MEMORY
{
m_boot               (RX) : ORIGIN = 0x00000000, LENGTH = 0x00008000
m_interrupts          (RX) : ORIGIN = 0x00008000, LENGTH = 0x00000400
m_text                (RX) : ORIGIN = 0x00008400, LENGTH = 0x00077C00
m_flash_nvm           (RX) : ORIGIN = 0x10000000, LENGTH = 0x00020000
m_flex_ram           (RX) : ORIGIN = 0x14000000, LENGTH = 0x00001000
m_data                (RW) : ORIGIN = 0x1FFF0000, LENGTH = 0x0000FC00
m_stack               (RW) : ORIGIN = 0x1FFFFC00, LENGTH = 0x400
m_data_2              (RW) : ORIGIN = 0x20000000, LENGTH = 0x00010000
m_bbram               (RW) : ORIGIN = 0xA0000000, LENGTH = 0x00080000
}

HEAP_SIZE = 0xFC00;
STACK_SIZE = 0x0400;
M_VECTOR_RAM_SIZE = 0x0;

TARGET(binary)
INPUT(bootloader.bin)
OUTPUT_FORMAT(default)

/* Define output sections */
SECTIONS
{
.boot :
{
    bootloader.bin (.data)
    . = ALIGN(4);
} >m_boot

/* The startup code goes first into internal flash */
.interrupts :

etc.

/********************************************/

But now I am trying to link a .bmp file in a KL33 project with no luck using the following link script:

/********************************************/

TARGET(binary)
INPUT(Icon.bmp)
OUTPUT_FORMAT(default)

/* Define output sections */
SECTIONS
{

/* The startup code goes first into internal flash */
.interrupts :
{
    __VECTOR_TABLE = .;
    . = ALIGN(4);
    KEEP(*(.isr_vector))     /* Startup code */
    . = ALIGN(4);
} > m_interrupts

.flash_config :
{
    . = ALIGN(4);
    KEEP(*(.FlashConfig))    /* Flash Configuration Field (FCF) */
    . = ALIGN(4);
} > m_flash_config

.bitmaps :
{
. = ALIGN(4);
Icon.bmp (.data)
} >m_text

/********************************************/

The first error of several I get is:

ZS.elf section `.data' will not fit in region `m_data'

I have commented out the .bitmaps section, and even commented out the INPUT(Icon.bmp) line and still get the error. So it must have something to do with the TARGET() and/or OUTPUT_FORMAT() commands? Any help would be appreciated.

Hello Michael,

- The error message "`.data' will not fit in region `m_data'" , it shows the .data overflow m_data section,

i think in your linker file , there is a section like :

.data:

{

...

}>m_data

So please send your linker file and .map file to me , or you can check the .map file by yourself to find

which data overflow , or too large .

- Please pay attention to that, the memory map is difference between K22 and KL33 .

-And i have a question , does these function out put to console or UART in your project ?

INPUT(Icon.bmp)
OUTPUT_FORMAT(default)

Hope it helps

Alice

Have a great day,
Alice Yang

Alice,

Please see

https://community.nxp.com/servlet/JiveServlet/download/328202-1-362661/Merging%20applications%20using%20Kinetis%20Design%20Studio.pdf

to see where I originally learned how to merge a bootloader with my K22

application.

I thought it would carry over, but it didn't.

TARGET, INPUT, and OUTPUT_FORMAT are ld script commands controlling

files that can be input to the gcc linker. I got them from the "Merging

applications using Kinetis Design Studio.pdf" document.

Through trial and error, I was able to get the linker to work for the

KL33 project by changing the OUTPUT_FORMAT(default) command to

TARGET(default). I don't know why.

Hi Mike,

Thanks for your sharing, i have not test this tutorial.

For size of KL33 RAM is smaller than K22, so maybe the "OUTPUT_FORMAT(default)"

need more RAM usage, so it overflow . In the error message, does it show what the size overflowed?

Alice,

The console log is attached for when I changed TARGET(default) back to

OUTPUT_FORMAT(default) in the .ld file.

There is no mention of "overflow" now, nor is there a .map file

generated. But I do remember getting a .map file before, maybe in some

other trial and error attempt. The .map file then showed m_data overflow.

I don't remember all the details anymore, only that it is now working

with TARGET(default).

Alice,

I sent you the wrong console file. Please do not publish it. This is

the correct on.
