Hi Antrou, I'd suggest to open the RTT viewer/client to see the debug log, this might show why it gets stuck at 0%. I suspect that the pre-validation step may have failed in your case.

Hi Vidar,

Thanks for your response but I still cannot run your example, I'm using nrfutil v2.2.0 but as you said earlier it should not be a problem for running your serial bootloader. Here is the procedure I'm following in order to execute your code :

Flash the bootloader : make flash (example/dfu/bootloader_secure_serial/pca10028_debug/armgcc/)
Send the softdevice : nrfjprog --program s130_nrf51_2.0.1_softdevice.hex -f NRF51 --reset
Send the new application : nrfutil --verbose dfu serial -pkg dfu_test_app_hrm_s130.zip -p /dev/ttyACM0

After these commands, the transfer stays stuck at 0% but no error appears, it seems to be in an infinite loop, and will never return an error.

I'm using the DK PCA10028 and GCC for compiling.

Am I doing something wrong ? Thanks !

I've verified that it worked with 2.1.0, but v.2.2.0 should work as well. Note that the example is configured to use hardware flow control (CTS/RTS) on the uart interface.

Hi Vidar, Which nrfutil version are you using for performing the transfer with this experimental example ? Thanks !

I just scoped it and there are no transmissions at all on both RX or TX before I abort nrfutil command.. im using nrfutil 2.1.0 installed from pip

these components does not rely on the sdk_config.h to be enabled, and there would have been compilations errors if they were. That said, it's interesting that the packet receipt notification is received only after the nrfutil process is aborted. I would suggest to probe/sniff the uart communication to check if any packets are being sent before the nrfutil process is terminated.

Vidar, sorry for the late reply, had to deal with CONFIG_GPIO_AS_PINRESET first.. I tried to recompile with the settings you have, but it didnt help. What I noticed is that I dont have SLIP_ENABLED and NRF_QUEUE_ENABLED options in my sdk_config.h The project compiles without any errors though. May be that could be the problem?

One more interesting thing if I enable nrfLOGging I see the following:

:INFO:Inside main
 0> :INFO:In nrf_bootloader_init
 0> :INFO:In real nrf_dfu_init
 0> :INFO:running nrf_dfu_settings_init
 0> :INFO:Enter nrf_dfu_continue
 0> :INFO:Single: Invalid bank
 0> :INFO:Enter nrf_dfu_app_is_valid

 0> :INFO:After nrf_dfu_transports_init
 0> :INFO:Waiting for events
 0> :INFO:Set receipt notif
 0> :INFO:Sending Response: [0x2, 0x1]

The last two lines appear when I abort DFU on command line.

Please try again with the configuration shown in screenshot above.

Dont have a DK unfortunately. Im using an FTDI converter it connects to P0.23, 0.24 and flow control is disabled.

Vidar Berg — Wed, 01 Feb 2017 13:30:12 GMT

ok, could be related to board differences. Do you have a DK you can test with? If not, what do you use for USB<->UART bridging? Also, is flow control enabled/disabled?

Vidar, Im using 52 custom board and Keil compiler.

Hi Sergey,

let my try to reproduce; are you using a 51 or 52 kit, and GCC or Keil?

Hi Vidar,

just tried to make an update, but when I run nrfutil nothing happens, progress bar stays at 0% and cmd line window just hangs. I checked if there was print out on RTT Viewer, but also nothing. Any ideas?

Hi Vidar, thanks a lot, this helps tremendously, Im going to check it out. Do you may be have some draft explaining protocol? Id need to write an updater program in C.. Thanks very much!

Hello, we plan to add serial dfu over UART in upcoming SDK release, but documentation is not ready yet. The packet format will however be quite similar to our existing BLE transport .

I have already made an experimental example of serial DFU based on an early beta release of the official uart transport. Have attached it here in case you want to try it.

nRF5_SDK_12.1.0_MOD_serial_dfu_240117.7z
