Problem with UART DFU

[Crespum]

Hi,

I'm trying to test the DFU over HCI included in the SDK examples but I can't make it work. This is all the information of the environment I'm using:

• SDK: 10.0.0
• Board: nRF51-DK
• Softdevice: s130
• Memory allocation: dual bank
• OS: Debian testing
• GCC version: gcc-arm-none-eabi-5_2-2015q4 (I had to modify Makefile.posix)

I'm following the next steps:

1. Make the bootloader at $SDK_PATH/examples/dfu/bootloader/pca10028/dual_bank_serial_s130/armgcc
2. Program the bootloader: nrfjprog -f nrf51 --chiperase --reset --program $SDK_PATH/examples/dfu/bootloader/pca10028/dual_bank_serial_s130/armgcc/nrf51422_xxac.hex
3. Program the SoftDevice: nrfjprog -f nrf51 --reset --program $SDK_PATH/components/softdevice/s130/hex/s130_nrf51_1.0.0_softdevice.hex
4. Finally use nrfutil 0.5.1 to send the example app through USB: nrfutil --verbose dfu serial --port /dev/ttyACM0 --baudrate 38400 --flowcontrol --package $SDK_PATH/examples/dfu/hci_dfu_send_hex/test_images_dual_bank_update_nrf51/dfu_test_app_hrm_s130.zip

And this is the output of nrfutils. It stops right after the first data packet:

Timed out waiting for acknowledgement 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 requirements 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.

Is anyone else experiencing this problem? Am I doing anything wrong?

Thanks for your help.

Even i am facing the similar issue on windows as crespum,
