Question about nrf9160 DK ROM

Loren Rogers

Hello,

I have been evaluating the nrf9160 DK board.  And my application is using mbedtls (vanilla) and TFM (Used https_client as a starter project).  The problem is that with that I am limited to 196k of flash space.  But when I build something like lpuart I have the full 1 meg.  What is gobbling up 800k with the latest https_client sample so that I can only have a max flash size of 196k?

Thank you

/Loren

    Hi

    How do you read out how much flash space you have accessible?

    Hi Sigurd. Thank you for getting back to me. I'm honestly not sure what was going on.  But I am 100% certain I was getting flash size exceeded errors during builds by a fairly large amount.  I would do a build I would see the following (similar) output:

    1> Linking ‘zephyr.elf’
    1> Memory region Used Size Region Size %age Used
    1> FLASH: 214316 B 960 KB 21.80%
    1> SRAM: 74000 B 178968 B 41.35%
    1> IDT_LIST: 0 GB 2 KB 0.00%
    1> Post-link command

    As you can see the above FLASH is correct with 960KB.  But I am 100% certain the available bytes was 196Kbytes.  And the %age used for FLASH was 100%.

    But things seem to be working correctly now.  For another reason, I had to completely uninstall and re-install the nordic connect SDK stuff, and now it seems to be correct.

    You can close this ticket.
