bootloader does not fit in flash.

[Johan.h]

Using 512K NRF52832, the code after minimum size optimization takes 255K.

Trying to add MCUBOOT, I get an error that it does not fit in flash.

I tried:

CONFIG_BOOT_SWP_USING_MOVE=y

but this did not build.

What are my options?

Thanks

This device is not using DCDC converter, and I assume that this is the problem. I could not find the correct config value to use the LDO.

Who to configure?

I tried:

CONFIG_DCDC_NRF52X=n

CONFIG_BOARD_ENABLE_DCDC_APP=n

both are undefined.

Thanks

Hello,

If you need to support DFU over BLE and not over UART, you will either have to reduce the size of your application or add an external SPI NOR flash IC to your design to place your secondary slot in. 

Typical flash memory layout when using MCUBoot on the 52832 without ext. flash

Best regards,

Vidar

I guess this reply was meant to be a response to your other ticket here:  NRF52832 does not start after power up.

Of course...   :-0

sorry for this confusion.
