Ok. thanks for your reply.

I tried dfu over serially and gets successfull recently.

I recommend to use dfu over serial also if you are using two MCU's that can useful in remote locations.

sorry. I didn't try dfu over serial as our priority is dfu over ble.

Oh no. I didn't proceed with this method, I use ble to perform dfu directly.

Hi inghowe83,

is it resolved?

I think you need to check hardware flow control and also data over Tx and Rx line.

are you using secure bootloader example? what changes you made in sdkconfig?

Ing Howe, the bootloader support different transport layers. We currently have support for over the air DFU over BLE, or serial DFU over UART and USB for the 52840. So the steps to do DFU depends on which bootloader you have programmed on your chip.

Recommend to go through the following documentation to get an overview of our DFU implementation:

Also, suggest that you create a new thread for this since it's unrelated to the problem OP had.

Hi @Vidar Berg

Tested using usb_serial. Not working as well.

By the way I follow the step from the following blog, is the step still valid?

devzone.nordicsemi.com/.../getting-started-with-nordics-secure-dfu-bootloader

I managed to progress until "Step D. Test DFU"

Thanks. I have tried nrfutil too and I received the following error. Tested with 115200 baud rate too.

Hi,

The serial DFU feature in nRFgo studio supports the legacy bootloaders only (pre-SDK 12). For the new secure DFU bootloaders you can use nrfutil.

Hi There,

Did you managed to resolve your prob? I facing this issue with s132_nrf52_5.0.0_softdevice using nRFgo studio with the following message.

Timed out waiting for acknowledgement from device.

Failed to upgrade target. Error is: No data received on serial port. Not able to proceed.

Brian did you accomplished to solve this bug? were you able to load the files?

I tried nRFgo Studio and this worked. However, I would still like to get the command line version of this working since it needs to be run in a production and scripted environment. I changed my original command line and replaced "--port 11" with "--port COM11", and this got me further. However, it still did not succeed. I'm now getting the following error:

C:\Program Files (x86)\Nordic Semiconductor\nRFgo Studio>nrfutil.exe dfu serial --package C:\Firmware\strobe\build\obj_strobe\strobe.zip --port COM11 --flowcont rol --baudrate 38400

Upgrading target on COM11 with DFU package C:\Firmware\strobe\build\obj_strobe\s trobe.zip. Flow control is enabled. [------------------------------------] 1% 00:18:17Timed out waiting for ac knowledgement from device.

Failed to upgrade target. Error is: No data received on serial port. Not able to proceed.

Possible causes:

bootloader, SoftDevice or application on target does not match the requirement s in the DFU package.
baud rate or flow control is not the same as in the target bootloader.
target is not in DFU mode. If using the SDK examples, press Button 4 and RESET and release both to enter DFU mode.

So it looks like my command line is still off, but not sure where. Any suggestions?

Hi, you can use nRFgo studio if you want a GUI for this. See the nRF5x bootloader item listed in Device manager. However, the approach you describe above should work. Please try with nRFgo studio and see if you still get the same error.

EDIT 16.11 Tried the same in the command line:

I suggest to try with the same arguments and check if it still doesn't work.
