ERROR_INVALID_DATA at mesh DFU

[Gerry]

Hi 

I try to implement DFU to our application using Mesh_SDK 2.0.1 and 
nRF5_SDK_15.0.0 

When I use the DFU-Example everything works fine. I then implemented the 
DFU-code from the example to our client application to be able to update it 
(without provisioning of servers at the moment). 

To program the device I use: 

cd pc-nrfutil-mesh_dfu 
nrfutil dfu genpkg --application 
../../Source/connectivity_client/build/connectivity_client_Debug/connectivit 
y_client.hex --company-id 0x00000059 --application-id 1 
--application-version 1 --sd-req 0x00A9 --mesh client.zip 
cd dfu 
python device_page_generator.py -d nrf52840_xxAA -sd "s140_6.0.0" -o 
../client.hex 
cd .. 
nrfjprog --eraseall 
nrfjprog --program 
../../Mesh_SDK/bin/softdevice/s140_nrf52_6.0.0_softdevice.hex --chiperase 
nrfjprog --program 
bootloader/mesh_bootloader_serial_gccarmemb_nrf52840_xxAA.hex 
nrfjprog --program 
../../Source/connectivity_client/build/connectivity_client_Debug/connectivit 
y_client.hex 
nrfjprog --program client.hex 
nrfjprog --reset 

For DFU I use: 

cd pc-nrfutil-mesh_dfu 
nrfutil dfu genpkg --application 
../../Source/connectivity_client/build/connectivity_client_Debug/connectivit 
y_client.hex --company-id 0x00000059 --application-id 1 
--application-version 2 --sd-req 0x00A9 --mesh client.zip 
cd dfu 
python device_page_generator.py -d nrf52840_xxAA -sd "s140_6.0.0" -o 
../client.hex 
cd .. 
nrfutil --verbose dfu serial -pkg client.zip -p COM19 -b 115200 -fc --mesh 

This seems to work in the beginning, but then throws an error: 

Flushing com-port...

Failed to upgrade target. Error is: Device returned status code 
ERROR_INVALID_DATA (135) on a DFU data packet. 


What could be the problem here?

Hi,

Although probably not related to the error, I see that the application version actually sent is version 5 (59000000010005000000), while the command suggest it should be version 2 (nrfutil dfu genpkg (...)
--application-version 2 (...).)

I see from the log that there are actually two errors. The latest one is ERROR_INVALID_DATA (135), in hexadecimal 0x87, and it happens four times:

target -> PC: 03847887 
PC -> target: 1978fcff0100c9d339f400f0032059620200896202008b620200 
target -> PC: 03847887

PC -> target: 1978fcff0100c9d339f400f0032059620200896202008b620200 
target -> PC: 03847887 

Before that there is error 0x83 ERROR_INVALID_STATE:

1978fcff0100c9d339f400f0032059620200896202008b620200 
target -> PC: 03847883 

The ERROR_INVALID_STATE may occur if the following was not handled correctly:

target -> PC: 16a6045900000001000500000059000000010001000000

This is the NRF_MESH_EVT_DFU_FIRMWARE_OUTDATED_NO_AUTH event.

Is the handler added the same way as in the DFU example, and does it handle the NRF_MESH_EVT_DFU_FIRMWARE_OUTDATED_NO_AUTH case, also as in the DFU example, calling either nrf_mesh_dfu_request() or nrf_mesh_dfu_relay()? Failing to do so might lead to the invalid state experienced.

Terje

Thanks for your response Terje

I copied the code from your link into my project, to make sure everything is correct. I also put some log-messages into the events to see what happens on the client.

At programming, my application-id is now set to 100, the application-version is set to 5
nrfutil dfu genpkg --application ../../Source/connectivity_client/build/connectivity_client_Debug/connectivity_client.hex --company-id 0x00000059 --application-id 100 --application-version 5 --sd-req 0x00A9 --mesh client.zip
python device_page_generator.py -d nrf52840_xxAA -sd "s140_6.0.0" -o ../client.hex

At DFU, my application-id is now set to 100, the application-version is set to 6
nrfutil dfu genpkg --application ../../Source/connectivity_client/build/connectivity_client_Debug/connectivity_client.hex --company-id 0x00000059 --application-id 100 --application-version 6 --sd-req 0x00A9 --mesh client.zip

The transfer works, but in my Log messages I can see, that in fw_updated_event_is_for_me() the app_id and app_version are wrong
and the client tries to relay instead of request himself (application-id should be 100 at programming and DFU)

Log-messages of the client:

 I had expected a current app_version: 5 and a current app_id: 100
 
 Can you see, what's wrong here?

Hi Terje

When I run my scripts with the DFU_Example, it works, so my scripts seem to be ok.
Then I compared the Log-output of the working DFU-Example and of my client.

Hi Terje

If I power cycle the device after programming, the "Crash on first packet" disapears. Then I only have an ERROR_INVALID_DATA.

The output now looks as follows:

for programming i use:

(
  echo {
  echo     "bootloader_config": {
  echo        "bootloader_id": 1,
  echo        "bootloader_version": 1,
  echo        "company_id": 89,
  echo        "application_id": 1,
  echo        "application_version": 1
  echo    }
  echo }
) > bootloader_config_default.json

nrfjprog --program ../../Source/connectivity_client/build/connectivity_client_Debug/connectivity_client.hex

nrfjprog --reset

For DFU:

nrfutil dfu genpkg --application ../../Source/connectivity_client/build/connectivity_client_Debug/connectivity_client.hex --company-id 0x00000059 --application-id 1 --application-version 2 --sd-req 0x00A9 --mesh client.zip

nrfutil --verbose dfu serial -pkg client.zip -p COM%Comport% -b 115200 -fc --mesh

Can you see what's going wrong here?

[Chaabane]

I'm having the same problem aswell, any leads ?

[Chaabane]

it seems that the erase sequence takes too much time. I explicitly added --i 500 to the dfu serial command and it seems to be working but it take 42 minutes to do DFU instead of 10 minutes.

500ms is the default value based on the help!

[Gerry]

Setting --i to 500 did not solve my Problem.

[Chaabane]

It's not a long term solution anyway. I guess we'll have to wait for nordic support

[tesc]

Hi,

I am very sorry for the delay, it looked like you had found a workaround but now I realize it did not work for you all.

You can try to increase SEND_START_DFU_WAIT_TIME in dfu_transport_mesh.py. (In the python source for nrfutil mesh branch.) Try setting it to 3.0 first, and increase it even a bit more if that is not sufficient. The larger the application, the more you might have to increase it.

Regards,
Terje

[Gerry]

Hi, 

Changing SEND_START_DFU_WAIT_TIME to 3.0 helped to ged rid of the "crash on start package". It now returns with ERROR_INVALID_PARAMETER after a while as you can see below. Further increasing of SEND_START_DFU_WAIT_TIME doesn't help.

Hi,

It looks from the log like you run the standalone bootloader. That one returns fewer status messages, which may make it a bit hard to figure out.

The first error message is NRF_INVALID_STATE (0x83, or in decimal 133). I talked to our mesh guys, and when you get NRF_INVALID_STATE after having sent the first data packet, it (usually) means there is not enough available space for the new download so it cannot begin. The bootloader then jumps back to the previous stage (you will see that after the NRF_INVALID_STATE return message the first 1978fc... messages from target to PC are repeated, and the target is back in that state.

Terje

Hi, is it a problem of the size (318kB Hexfile) or can we solve this with the Flash_placement?
