If you are using the softdevice, you need to flash the softdevice along with your application, as described in the Running examples that use a SoftDevice chapter in the SDK documentation.

and tried to run from: 0x00023000
One question:
Do I need to load some lib to the flash memory before load my program?

I tried with SDK 14

If you are using a softdevice, the softdevice will be located in the start of flash (ROM), as described in the SoftDevice memory usage specifications. Which SDK and softdevice version are you using?

ROM start from 0x000000000, see page 24

In your first linker file, it doesn't seem reasonable that the ROM would start @ 0x00000, What is currently your start address and length for RAM and ROM ? Are you using a Soft Device ? What error is the linker giving you ?

The RAM and ROM in Linker were changed to 256k ROM and 32 kRAM.(in the Linker code which I sent - it's changed)

I tested with #define NRF_SDH_CLOCK_LF_SRC 0 too, the same(, but I see in asm code, it stucked in handler:
SVC_Handler

For example for xxaa was Linker file:

/*###ICF### Section handled by ICF editor, don't touch! ****/
/*-Editor annotation file-*/
/* IcfEditorFile="$TOOLKIT_DIR$\config\ide\IcfEditor\cortex_v1_0.xml" */
/*-Specials-*/
define symbol __ICFEDIT_intvec_start__ = 0x23000;
/*-Memory Regions-*/
define symbol __ICFEDIT_region_ROM_start__ = 0x23000;
define symbol __ICFEDIT_region_ROM_end__ = 0x7ffff;
define symbol __ICFEDIT_region_RAM_start__ = 0x20001720;
define symbol __ICFEDIT_region_RAM_end__ = 0x2000ffff;
export symbol __ICFEDIT_region_RAM_start__;
export symbol __ICFEDIT_region_RAM_end__;
/*-Sizes-*/
define symbol __ICFEDIT_size_cstack__ = 0x800;
define symbol __ICFEDIT_size_heap__ = 0x200;
/**** End of ICF editor section. ###ICF###*/

define memory mem with size = 4G;
define region ROM_region = mem:[from __ICFEDIT_region_ROM_start__ to __ICFEDIT_region_ROM_end__];
define region RAM_region = mem:[from __ICFEDIT_region_RAM_start__ to __ICFEDIT_region_RAM_end__];

define block CSTACK with alignment = 8, size = __ICFEDIT_size_cstack__ { };
define block HEAP with alignment = 8, size = __ICFEDIT_size_heap__ { };

initialize by copy { readwrite };
do not initialize { section .noinit };

keep { section .intvec };
place at address mem:__ICFEDIT_intvec_start__ { readonly section .intvec };
place in ROM_region { readonly };
place in RAM_region { readwrite,
block CSTACK,
block HEAP };

But when I change the addresses from:

define symbol __ICFEDIT_region_ROM_end__ = 0x7ffff;->define symbol __ICFEDIT_region_ROM_end__ = 0x3ffff;

and

define symbol __ICFEDIT_region_RAM_end__ = 0x2000ffff;->define symbol __ICFEDIT_region_RAM_end__ = 0x20007fff;

It doesn't start.

Yes, if your new chip has less flash and ram, you will definitely have to update the linker file. Should be reasonably straightforward to work out the new sizes.

I would look at the example project linker files to work out the start and size of the flash and ram, then update those for the smaller capacity chip.

I think you want to change it to 0 (not 2) for RC ?

RE: Problem with nrf52832 xxab.

Sergii — Sun, 04 Feb 2018 21:03:00 GMT

do I need to change Linker?

Hello,

Thank you for your responce, I tried to do it and got an error, but fuction out. I will write the code in 10 minutes

Tried to change 1 to 2:

// <0=> NRF_CLOCK_LF_SRC_RC // <1=> NRF_CLOCK_LF_SRC_XTAL // <2=> NRF_CLOCK_LF_SRC_SYNTH

#ifndef NRF_SDH_CLOCK_LF_SRC

#define NRF_SDH_CLOCK_LF_SRC 2

#endif

The same, but I put in linker file:

/*###ICF### Section handled by ICF editor, don't touch! ****/
/*-Editor annotation file-*/
/* IcfEditorFile="$TOOLKIT_DIR$\config\ide\IcfEditor\cortex_v1_0.xml" */
/*-Specials-*/
define symbol __ICFEDIT_intvec_start__ = 0x0000;
/*-Memory Regions-*/
define symbol __ICFEDIT_region_ROM_start__ = 0x00000;
define symbol __ICFEDIT_region_ROM_end__ = 0x0003FFFF;
define symbol __ICFEDIT_region_RAM_start__ = 0x20000000;
define symbol __ICFEDIT_region_RAM_end__ = 0x20007FFF;
export symbol __ICFEDIT_region_RAM_start__;
export symbol __ICFEDIT_region_RAM_end__;
/*-Sizes-*/
define symbol __ICFEDIT_size_cstack__ = 0x900;
define symbol __ICFEDIT_size_heap__ = 0x800;
/**** End of ICF editor section. ###ICF###*/

define block CSTACK with alignment = 8, size = __ICFEDIT_size_cstack__ { };
define block HEAP with alignment = 8, size = __ICFEDIT_size_heap__ { };

initialize by copy { readwrite };
do not initialize { section .noinit };

keep { section .intvec };
place at address mem:__ICFEDIT_intvec_start__ { readonly section .intvec };
place in ROM_region { readonly };
place in RAM_region { readwrite,
block CSTACK,
block HEAP };

Have a look at the

#define NRF_SDH_CLOCK_LF_SRC 1

in your sdk config file
