Porting LCF file

tiagoguimaraes — Thu, 14 May 2015 12:30:42 GMT

Good Morning,

I'm doing the inclusion of a bootloader on uC Kinetis using the GCC compiler. For this I am using the document "MCU_Kinetis_GCC" but had the problem include the binary file described in step 14c the page 45. This step says the following:

14. INCLUDE filename

CW LCF:

.my_text{ INCLUDE filename }>my_text

GCC LD:

Equivalent syntax in GCC LD,

INPUT(file, file, ...) INPUT(file file ...)

Command line options to include binary file [default section as .data.]

NOTE

Binary filename: data.raw, Format: binary

a. Create a stationary project.

b. Go to Properties > C/C++Build > Settings > ARM Ltd. Windows GCC C

Linker > Miscellaneous > Other flags

c. Add the following options. -Wl,-b,binary,"C:/data.raw",-b, elf32-littlearm

This makes linker to treat data.raw as raw binary and resume to elf32-littlearm

for subsequent objects.

The final elf will contain the following symbols for the sources to manipulate the

data:

_binary_C___data_raw_start _binary_C___data_raw_end _binary_C__data_raw_size

The default linker section will be .data.

To place the raw data in a specified linker section, define the section in the

Linker command file.

a. Define the following section.

MEMORY{

m_srecord (RX) : ORIGIN = 0x0000C000, LENGTH = 0x00004000/*define its memory

segment*/

}

TARGET(binary)/* specify the file format of binary file */

INPUT (data.raw)/* provide the file name */

OUTPUT_FORMAT(default)/* restore the out file format */

/* Define output sections */

SECTIONS

{

.srecord :

{

data.raw (.data)

. = ALIGN (0x4);

} > m_srecord

.text:

{

}>m_text

}

b. Add the path of the file added in the previous step to ARM Ltd. GCC C

Linker->Libraries->Library search path (-L)

When I finish running this script the following error is generated by the compiler :

"C:/Freescale/CW MCU v10.6/Cross_Tools/arm-none-eabi-gcc-4_7_3/bin/arm-none-eabi-gcc" @"MDL100_KL16Z128.args" -o"MDL100_KL16Z128.elf"

arm-none-eabi-gcc: error: elf32-littlearm: No such file or directory

mingw32-make: *** [MDL100_KL16Z128.elf] Error 1

The command that includes on step 14 (Add the following options. -Wl,-b,binary,"C:/data.raw",-b, elf32-littlearm) is the following:

-Wl,-b,binary,"${ProjDirPath}\FLASH\Boot_MK16Z128.bin",-b, elf32-littlearm

The command that includes on step 14 (Add the path of the file added in the previous step to ARM Ltd. GCC C Linker->Libraries->Library search path (-L)) is the following:

"${ProjDirPath}\FLASH\Boot_MK16Z128.bin"

Can you help me?

Hi Tiago,

I have been able to reproduce the issue you mention. When you copy the linker options from the document there is a space before elf32-littlearm:

-Wl,-b,binary,"C:/data.raw",-b, elf32-littlearm

This space is causing the issue, so please try removing the space and the error should be gone:

-Wl,-b,binary,"C:/data.raw",-b,elf32-littlearm

Hope it helps!

Best Regards,

Thanks for the answer , the solution provided is correct . The project is now compiling but still can not get the include " Boot_MK16Z128.bin ". I executed all the steps as indicated in section 14 of the document , however the data Boot loader still do not appear in .bin project that did include.

You have no idea what can be ?

Follows the excerpt from my LD file that do include :

MEMORY {

m_bootloader (RX) : ORIGIN = 0x00000000, LENGTH = 0x00004000

m_interrupts (RX) : ORIGIN = 0x00004000, LENGTH = 0x00000400

m_cfmprotrom (RX) : ORIGIN = 0x00004400, LENGTH = 0x00000100

m_app_info (RX) : ORIGIN = 0x00004500, LENGTH = 0x00000100

m_text (RX) : ORIGIN = 0x00004600, LENGTH = 0x0000D900

m_app_flash_vars (RX) : ORIGIN = 0x00011F00, LENGTH = 0x00000400

m_new_image (RX) : ORIGIN = 0x00012300, LENGTH = 0x0000D900

m_new_image_status (RX) : ORIGIN = 0x0001FC00, LENGTH = 0x00000400

m_data (RW) : ORIGIN = 0x1FFFF000, LENGTH = 0x00004000

}

TARGET(binary)/* specify the file format of binary file */

INPUT (Boot_MK16Z128.bin)/* provide the file name */

OUTPUT_FORMAT(default)/* restore the out file format */

SECTIONS

{

.bootloader :

{

Boot_MK16Z128.bin (.Boot_MK16Z128)

. = ALIGN (0x4);

} > m_bootloader

.app_info :

{

* (.info)

KEEP(*(.info))

. = ALIGN(0x1);

} > m_app_info

...

}
