Hi,

I am also having trouble with DFU. Have you solved this problem?

Best Regards,

Hello,

[quote user="Udi Vahaba"]*Question - why the list changed from the last list command?[/quote]

I tested this as well and encountered similar behavior. See my screenshot below. I doubt there is an issue with my implementation

I will investigate further and get back to you with more information

Kind Regards,

Abhijith

Hello,

Sorry for the delay. It is summer vacation here in Norway, and we are a bit understaffed. As a result, the workload is higher than usual, which is causing the delay. I haven't had time to look into this closely, but I will start working on it today. You can expect a response by Monday evening. I hope this will be fine, and I apologize for any inconvenience caused by this delay. I appreciate your brief explanation of the issue, as it will help me understand it clearly.

Kind regards,

Abhijith

I made more tests, this time i tracked the s0 and s1 data using JLinkExe.

i will split the tests for 2 sections.
First set - using the nRF Connect mobile app:

Build and flash clean application, saving s0 and s1 as binaries using JLinkExe savebin (e.g. savebin s1.bin 0x16200 49152)
convert them to hex using xxd.
increment CONFIG_FW_INFO_FIRMWARE_VERSION and made minor change in mcuboot main.c
build it, and using DFU on nRF Connect application with dfu_mcuboot.zip file
again, saving s0 and s1 as binaries using JLinkExe savebin and convert them to HexI compared the files (s0 from step 2 with s0 from step 5, and same for s1), they was exactly the same.
*Note that "mcuboot_secondary" data was change after the dfu process.

Second set - using mcumgr from terminal:

Build and flash clean application, saving s0 and s1 as binaries using JLinkExe savebin (e.g. savebin s1.bin 0x16200 49152)
convert them to hex using xxd.
increment CONFIG_FW_INFO_FIRMWARE_VERSION and made minor change in mcuboot main.c
build it, and now using only signed_by_mcuboot_and_b0_s0_image_update.bin
The majority of the following steps are redundant but I did them for any case because I'm not sure how mcumgr works:
1. mcumgr -c testDK image list
  result:
```
Images:
 image=0 slot=0
    version: 1.0.0
    bootable: true
    flags: active confirmed
    hash: aab3f9ced75b15b2de8bcd79181db246cc5311c684bb9b7f977f42837d6847b7
Split status: N/A (0)
```
2. mcumgr -c testDK image upload build/zephyr/signed_by_mcuboot_and_b0_s1_image_update.bin
3. mcumgr -c testDK image list
  result:
```
Images:
 image=0 slot=0
    version: 1.0.0
    bootable: true
    flags: active confirmed
    hash: aab3f9ced75b15b2de8bcd79181db246cc5311c684bb9b7f977f42837d6847b7
 image=0 slot=1
    version: 2.0.0
    bootable: true
    flags: 
    hash: e34ca28b43c839a1b082d71d5560ba853a928cfe22d7b4b549fb70e4452cdd83
Split status: N/A (0)
```
  *Note that this time the mcuboot_secondary partition didn't changed (I erased the area before)
4. Saved s0 and s1 using savebin, converting the to hex (I used prefix for each stage to not overwrite)
5. mcumgr -c testDK image confirm e34ca28b43c839a1b082d71d5560ba853a928cfe22d7b4b549fb70e4452cdd83
6. Saved s0 and s1 using savebin, converting the to hex (I used prefix for each stage to not overwrite)
7. mcumgr -c testDK reset
8. mcumgr -c testDK image list
  result:
```
Images:
 image=0 slot=0
    version: 1.0.0
    bootable: true
    flags: active confirmed
    hash: aab3f9ced75b15b2de8bcd79181db246cc5311c684bb9b7f977f42837d6847b7
Split status: N/A (0)
```
  *Question - why the list changed from the last list command?
9. At this point I saw that the firmware version not changed, nor the BOOT_LOG_INF I changed, so I decided to do another reset
10. mcumgr -c testDK reset
11. The firmware version is now changed and the BOOT_LOG_INF.
12. Saved s0 and s1 using savebin, converting the to hex (I used prefix for each stage to not overwrite)
13. Finally s1 and s0 are different.
  
  Through all the steps, s0 and s1 were not changed, only after step "L" there was a difference in s0 and s1 (relative to the prior steps).
  *Note that "mcuboot_secondary" data didn't change the whole time.

There is a hugh difference when using the FOTA DFU with zip or the mcumgr with bin file, where it somehow uses the mcuboot_secondary partition (maybe it thinks it is an application and not bootloader firmware?) when FOTA and does good job on mcumgr using bin file.

Sorry for the long explanation, but I'm trying to walk you through the way I test things, hope it helps you to understand the problem better.

I tried to DFU with nRF Connect mobile application, and it's not working as well.

I've added prints for the mcuboot_secondary partition memory - I had a bad feeling that it writes the new firmware to that partition (although it is not s0 or s1).
with that print, I can see that it puts data into the mcuboot_secondary partition after the upload via mobile app.

mcumgr image list:
first command - after flash and build
second command - after using nRF Connect application to upload dfu_mcuboot.zip

Log file from nRF Connect app:
devzone.nordicsemi.com/.../Log-2024_2D00_07_2D00_17-16_5F00_08_5F00_50.txt

Please note that I made change to the application too (only changed CONFIG_MCUBOOT_IMGTOOL_SIGN_VERSION="4.0.0+0")

Please also help me understand why the mcuboot_secondary partition changes when it should be written to s1.

RE: How to FOTA only mcuboot over BLE

Menon — Wed, 17 Jul 2024 09:06:07 GMT

Hello,

I wanted to inform you that I have been assigned to this case and have started investigating it. Could you please try using the nRF Connect mobile application to see if the same issue occurs? In the nRF Connect mobile application, you can find a DFU button in the top right corner after establishing a connection.

Additionally, could you check the log from the nRF device and let me know if there are any error messages? Please share those logs as well.

Kind regards,

Abhijith
