DFU bootloader prevents to load app hex

[fab]

Hi all,

I am on the DK-52 with the SDK 13.0.0.

After erasing the device, I follow this steps:

1. upload the softdevice

   nrfjprog --reset --program s132_nrf52_4.0.2_softdevice.hex --family NRF52

2. upload the bootloader (bootloader_secure_ble)

   nrfjprog --reset --program nrf52832_xxaa_s132.hex --family NRF52

After that the bootloader enters in DFU mode (LED1 and LED3 on)

If I try to upload my app firmware:

nrfjprog --reset --program pollen_device.hex --sectorerase --family NRF5

I get this error:

Argument provided has a wrong value. Memory access not aligned, value outside of range or similar

If I try to upload the app from my iPhone (using iOSDFULibrary) I am able to upload the app firmware, the device resets and the app starts correctly.

My app firmware has:

FLASH_START=0x1F000
SRAM_START=0x20001fe0

How do I correctly upload the app firmware via nrfjprog?

Thank you.

Thanks, Aaron. As far as I understand, I cannot upload the app firmware using the nfrjprog anymore but I have to use the nrfutil. I have prepared the pkg file as usual:

nrfutil  pkg generate --hw-version 52 --sd-req 0x98 --application-version 0x01 --application pollen_device.hex --key-file priv.pem pollen_device_fw.zip. 

Then I have tried: nrfutil dfu ble -pkg pollen_device_fw.zip -ic NRF52

but I get this error: Fatal Python error: PyThreadState_Get: no current thread Abort trap: 6. I am on macOS 10.13.1. Is this the right procedure? Any suggestion?
