At the moment a huge part of the support team is currently on vacation, and you may experience delayed answers.

You could check out this link, which discusses occurring usage faults when CONFIG_NO_OPTIMIZATION=y. However, it seems like that is for an older NCS version, so I'm not sure if it's related.

If that link didn't help, please ask and I will look into it in more details/get in touch with the developers.

However, if you had a simple way (step-by-step) for me to reproduce this behavior that would be helpful.

Best regards,

Simon

Hi Simon, My colleague was debugging the same and recommends the following config:

CONFIG_NO_OPTIMIZATIONS=n
CONFIG_SIZE_OPTIMIZATIONS=n

This fixed the fault and I can proceed. Apparently there are some constraints on the AT command buffers based on these settings. Can you help us understand these configs better? why did it work?

Hi Simon,

Yes let me clarify:Flash issue is now compiling and i have tested that it works. Thanks.

For the lte_lc driver compilation issue, by including <zephyr.h> along with <modem/lte_lc.h> compilation issue is resolved. but when i run it, I get the usage fault. shown below:

devzone.nordicsemi.com/.../zephyr.lst

#include <zephyr.h>
#include <modem/lte_lc.h>
#include <stdio.h>

int lte_init_connect(){
	int err= lte_lc_init();
	if (err) {
		printf("lte_lc_init failed: %d\n", err);
		return err;
	}
	else{
		int err = lte_lc_connect();
		if (err) {
			printf("lte_lc_connect failed: %d\n", err);
			return err;
		}
	}
	return 0;
}
void main(void){
	int err = lte_init_connect();
	if(err){
		return;
	}
}

The "lst" file is attached. Let me know if I can provide further details. I hope you can help me because I am currently blocked by this issue. I have no choice but to revert to 1.2.0 which unfortunately does not support external flash addition which is my final goal. My prj.conf remains the same as shared earlier.

Okay, to make it clear: The "DT_FLASH issue" is resolved and the "Compilation/usage fault issue" is not?

Quick update: The changes you mentioned for flash macros similar to the nvs test compile for v1.3.0.

Sorry for the delay, I've been quite busy lately. I will try to get to the bottom of this before Friday.

Best regards,

Simon

Sorry for the delayed response.

Compilation/usage fault issue: Simplified Code

void main(void){

int err= lte_lc_init();
if (err) {
printf("lte_lc_init failed: %d\n", err);
}

else{

int err = lte_lc_connect();
if (err) {
printf("lte_lc_connect failed: %d\n", err);
}}

}

This doesn't compile for me. here is my prj.conf:

And i use cmake and ninja to compile:

ninja -C build

For DT_FLASH issue: I will check and respond on Monday.

Compilation/usage fault issue:

How can I reproduce the compilation issue? Could you provide me with some piece of code or upload your sample?
Regarding the usage fault, could you check what function resides at the faulting instruction address. Search for the address in the file build\zephyr\zephyr.lst

DT_FLASH issue:

I can see that the lines fs.offset = DT_FLASH_AREA_STORAGE_OFFSET and

flash_get_page_info_by_offs(device_get_binding(DT_FLASH_DEV_NAME)..) fails. Could you try to use the approach in ncs\zephyr\tests\subsys\fs\nvs\src\main.c-->test_nvs_init()?

#define TEST_FLASH_AREA_STORAGE_OFFSET	FLASH_AREA_OFFSET(storage)
.
.
void test_nvs_init(void)
{
.
.
int err;
const struct flash_area *fa;
struct flash_pages_info info;

err = flash_area_open(FLASH_AREA_ID(storage), &fa);
zassert_true(err == 0, "flash_area_open() fail: %d", err);


fs.offset = TEST_FLASH_AREA_STORAGE_OFFSET;
err = flash_get_page_info_by_offs(flash_area_get_device(fa), fs.offset,
				  &info);
.
.

Simon
