Running out of memory early with nrf52832 and example/ble_app_uart

[riceman0]

So, I am adapting and adding to a project based on the example app with SDK16.0 and softdevice s112.  I'm using Keil.

My nrf52832 has 256kb flash, 32k ram.

I'm compiling fine at

Program Size: Code=29200 RO-data=3424 RW-data=420 ZI-data=6204  

But then I add *one* more line of code and I get a bunch of

.\_build\nrf52832_xxaa.axf: Error: L6406E: No space in execution regions with .ANY selector matching nrf_sdh_ble.o(.data).

Below are my compiler options, inherited from the example code.  It looks like my ROM is sized at 0x6700=421000 bytes and my RAM is sized at 0xDD38=56000 bytes.

This is way more than the size of my program (29k-35k flask, 6-7k ram), isn't it?  My softdevice (according to nrfconnect) is around 97k, so I should be fine.

What am I running into here, does anyone know?  I would have thought the example project was set up properly.

Thanks.

there is a mistake somewhere...

[riceman0]

oh yes youre right, but the mistake is that I have the AA variant with 512kb flash, 64k ram.  But neither number are close to my reported usage, right?  No mistake there, right?  Any thoughts as why im getting this linker error?

Sorry, no idea... it seems that your code size is close to 32k, but .data section is related to RAM. Maybe you've selected AB variant of 52832? Also what edition of Keil do you have? MDK-lite is limited by 32k code size (though an error message should be different).

If you can put your project here, we would have more chances to find what's wrong.
