nRF52810 DFU attempt

[maxx44]

I'm trying to set up DFU for a custom board with a nRF52810 module (Rigado BMD-330).  I created the secure bootloader from the recent project for SDK 15 posted by Vidar Berg.  All seems to be working and I can connect to the DFUTARG.  The DFU download appears to be going through the initial setup but is failing with an "INSUFFICIENT RESOURCES" message in the log file for the Execute phase.

I'm not too surprised and there's little flash space left for my application.  According to the memory map from nRFgo, the SoftDevice (s112 6.0.0) takes 100KB and the bootloader is 32 KB.  This leaves 60 KB for the application, which the compiler says is 53 KB.  I was hoping to squeeze in ...... but I guess not.

Am I totally out of luck for using OTA DFU here?

Thanks,

Max

What are you trying to re write with the bootloader?  Your application? stack? both?

I was just trying to write the application ..... at least all that was in the application build .hex file and put into a .zip package by nrfutil.  But this includes the stack as defined in the build doesn't it?

I'm new to DFU and using the bootloader, especially for the nRF52810.  I didn't attempt to do anything with bootloader settings, so I assume I got whatever the settings are for the bootloader project above and hoping that would work.  I went through the whole DFU process with the nRF52 DK using SDK examples and it seemed to work fine.  Let me know if you're aware of something extra that needs to be done. 

Thanks,  Max

I got this working.  As I said, I'm new to DFU ..... so I forgot to enable DFU service in the sdk_config.h file for my application.  I also disabled NRF_LOG function and disabled the uart, which helped reduce the size.  With all that the DFU package for my application downloaded and started running.
