nrf toolbox dfu max file size

[Andreas_Wickström]

Hi I have a problem when bootloading with nrf toolbox. It seems like when i flash files over 0x10000 in size the program overwrites itself. When i flash files with smaller size it works. I compile my program with gcc and use nrfutil to make a .zip file to download.

I seem to have solved the problem with the dfu. Atleast I think. It seems that we have a type error in the dfu. i changed the typedef uint32_t pstorage_size_t;

to uint32_t from uint16_t. It seemed like the it wraped around and that was why i got some wiered errors when i flashed my file. The nrf toolbox can then handle ihex 16 files

@Andreas: Which SDK version are you using ? I thought typedef uint32_t pstorage_size_t; has always been uint32_t ?

[Andreas_Wickström]

I use the latest SDK and it was defined as uint16_t there.

Strange, I just have a look at the SDKv11 .zip file here, and the definition of pstorage_size_t was uint32_t in the pstorage_platform in \examples\dfu\bootloader\config .

Could you double check ?

[Andreas_Wickström]

hi Seems like i have uses wrong file then. I made a copy from this filepath components\drivers_nrf\pstorage\config

[Hung Bui]

Oh, thanks Andreas. I think the configuration in the components\drivers_nrf\pstorage\config should be updated to uint32_t as well. I will report this internally.
