Migrating to SDK15, crashing at advertising_init()

[xhr0428]

I'm trying to migrate from SDK12 to SDK15, but my code always crashes at advertising_init() and goes to NRF_BREAKPOINT_COND. Even when I directly use the example from the service tutorial https://devzone.nordicsemi.com/tutorials/b/bluetooth-low-energy/posts/ble-services-a-beginners-tutorial. I'm wondering what's the issue in this case?

Also how do I define DEBUG here? I added CFLAGS += DDEBUG in makefile, but it didn't trigger the switch error ID part in app_error_default_handler function in app_error_weak.c.

I'm using Eclipse with both DK52 and DK52840. Any help is appreciated. Thanks.

Try CFLAGS += -DDEBUG

Also remove compiler optimization (to get expected debug results), OPT = -O0 -g3 , CFLAGS += $(OPT)

Try commenting out that line, //NRF_BREAKPOINT_COND;

Yes, I'm using this. I missed - in my typing.

I see OPT = -O3 -g3 and CFLAGS += $(OPT) in the makefile. Should I comment them out? It doesn't seem to run through after commenting out, it shows No source available for "main() at 0x30f62"

There is no stopping at app_error_weak any more, but I couldn't find the device on my phone. Probably there is still error?

I made the change for RAM (rwx) : ORIGIN = 0x20002220, LENGTH = 0xDDE0. But the error message stayed the same.

You still get nrf_sdh_ble: sd_ble_enable() returned NRF_ERROR_NO_MEM ?

Make sure that you compile the hex file again after the change. If that does not work, it could be that Eclipse overwrites the value somewhere in the Eclipse settings ?

Only saving the changes in ld file doesn't make it recompile. I changed device name in the main file to get it recompiled and it is working now. Let me work on my real application. What ram settings should I use for nRF52840? Still RAM (rwx) : ORIGIN = 0x20002220, LENGTH = 0xDDE0?

Great!

No, the nRF52840 has alot more flash and RAM. Take a look at the pca10056 projects to see how they are configured.

Example ble_app_uart in SDK 15.2 uses this by default: 

MEMORY
{
FLASH (rx) : ORIGIN = 0x26000, LENGTH = 0xda000
RAM (rwx) : ORIGIN = 0x20002a98, LENGTH = 0x3d568
}

Got it working, thanks
