DFU application doesn't seems to be updated

@saiteja: The size of .zip file or .hex file is not the size of the image on flash. You need to check the size when you compile the firmware, or you need to convert to .bin file to see the actual size

hi i am also facing same issue. when i create zip file it is giving 130kb around. how to reduce size of zip file using nrfutil i am using fallowing command to generate zip (SDK11 S132V2.0.0) ***

nrfutil.exe dfu genpkg --application app.hex --application-version 0xFF --dev-revision 0xFF --dev-type 0xFFFF --sd-req 0x81 dfu_app.zip

please help.

I restarted the bootloader code from scratch and uploaded a smaller application and now it works. Thanks a lot !

Hi Guillaume,

You can find the max size for dual bank by looking at DFU_IMAGE_MAX_SIZE_BANKED inside dfu_types.h. It's varied depends on your chip's flash size and the number of data page you reserved.

Please have a look here. If you take Application code, free/swap, and application data and divide by 2 you have the rough number of the max size you can have.

Hi,

I'll check that, do you know what is the maximum size of application for the dual bank DFU ? Just to be sure, the app size of 75kB is the .bin file size, isn't it ?

Hi Guillaume,

From the log I can see that you are updating a pretty big application with the size of 75kB (in hexa: 0x0125c8). The DFU bootloader responded with 0x100104 telling that the size exceed the maximum size (packet 5264). You may need to consider using single bank DFU update instead of dual bank update. See the memory layout here.

Simply replace dfu_dual_bank.c with dfu_single_bank.c and recompile the bootloader to make it work as single bank DFU.

Hi, Sorry for the delay. Here is the wireshark recording of a sniffer trace : WireShark file Could you please have a look ?

Hi Guillaume,

Please try to test with unmodified DFU bootloader. Please try to capture a sniffer trace when you do DFU update. And try to use nRF Master Control panel to do DFU instead of nRFToolbox app.

Finally I have downloaded Master Control Panel v 3.10.0.14 which contains nrfutil 0.3.0. I used the command line that you mentioned and downloaded the zip file with nRFToolbox on a target containing only the softdevice and the bootloader, but it still doesn't work, and I have (*((uint32_t *)app_addr) == EMPTY_FLASH_MASK) again. I also tried sending dfu_test_app_hrm_s130.zip, which is already in the SDK, but the same thing happens...

Hi, I have Master Control Panel v.3.6.0.8331, and unfortunately I don't have any nrf folder in it. Do you know where can I get the good version of nrfutil ?

Hi,

Seems that you are using the create image command for the DFU bootloader in SDK v12 and later. For SDK v11, you should follow this instruction. You should use the nrfutil.exe located at C:\Program Files (x86)\Nordic Semiconductor\Master Control Panel<version>\nrf\

The command should look like this:

nrfutil.exe dfu genpkg app.zip --application yourapplication.hex --application-version 0xffff --dev-revision 0xffff --dev-type 0xffff --sd-req 0xfffe

You can try to test using our provided .zip sample file in \examples\dfu\ble_dfu_send_hex

Hi, I am sorry if I didn't clarify enough, if I don't have any app flashed, I can't do a DFU update. It just restart in DFU mode without loading any app, and advertise as DFUTarg. I will look into the debug of the bootloader and maybe try an unmodified example. About the init packet, I am using nrfutil with the following command line :

nrfutil pkg generate --application app_helio_v2-00.bin --hw-version 2 --application-version 0x00000002 --sd-req 0x80 --key-file key.pem pckg_app_v2-00.zip

Hi Guillaume,

Could you clarify, if you don't have any app flashed, can you do a DFU update ? Or the device simply restart and you can't do any update ? Could you describe clearly what happens, would the device advertise as DFUTarg ?

Note that you can uncheck the optimization level and debug the bootloader to figure out why it restart/crash. You may need to follow this instruction on how to debug.

My suggestion is to try to test with the default, unmodified example. Also please describe how you generate the .zip file for DFU ? Have you tried to use a default .zip provided with the nRFToolbox ?
