can not download the hex file using IAR IDE?

[wdliming]

when i use the official example in nRF5_SDK_15.2.0_9412b96\examples\peripheral\blinky\pca10040e\mbr\iar using IAR IDE,

after building successfully, i failed to download the hex file~

the iar IDE  prompt 

warning  ：stack pointer is setup to incorrect alignment , stack addr = 0xFFFFFFFF

can any one explain why? thanks a lot!

Hi,

This example expects that the MBR is flashed to chip. (The project is located in a sub-folder called mbr). So to test this, you will need to flash the MBR, you can find the MBR .hex file in the folder SDK15_2_folder\components\softdevice\mbr\nrf52810\hex

thank you!
how can i flash the MBR hex file?
using nrfgostudio via program bootloader?
and i find there is no hex file in "SDK15_2_folder\components\softdevice\mbr\nrf52810\hex" directory

You can probably use the "Program Application" tab. That said, we have a new and better programmer app in nRF Connect for Desktop, you should check it out.

Is the folder empty?  The hex file should be called mbr_nrf52_2.2.2_mbr.hex

Ok, let me know if it fails again, and I can try to upload it here on Devzone.
