mcumgr image confirm returns error 3 while following the "Add DFU support to your application" walk-through (serial DFU)

[laurentc]

Add DFU support to your application walk-through
devzone.nordicsemi.com/.../ncs-dfu
Serial DFU chapter
Fails on a nRF52840 DK (with one HW change)
With error 3 on image confirm using mcumgr

All the previous steps seem fine.

nrf connect sdk 2.1.0

I tried increasing stack sizes with no success.

I ensured that the flash is fully erased before the first flash in case
Like in the walk-through, I did just rebuild the hello world sample to change the signature

The change I did to the nRF52840 DK, in case this could be of any effect
HW : disconnect the 32.768Khz quartz, reroute the wires so that P0.00 and P0.01 are the new USART0, pass through USB CDC
FW :
create an overlay to set the uart0 on P0.00 and P0.01
add to the prj.conf to run without the quartz 32.768Khz
# No 32.768Khz Quartz
CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n

I was able to run several other samples with this config with no problems.

Looking at the mcumgr source code
Error 3 seems to be LOG_MGMT_ERR_EINVAL in the mcumgr source code. May have to do with cbor_read_object or cbor_write_attr

Here are the logs

// yep, no change

I am stuck.

Hi,

Did you create an overlay for the MCUboot child image, or just for the application? The configs in the prj.conf file will only be applied to the application, and not to child images. You can specify Kconfig and devicetree overlays for child images as described in Image-specific variables and Child image devicetree overlays.

Best regards,
Jørgen

Hello.

I had not. So I tried adding  mcuboot.overlay into D:/ncs/v2.1.0/bootloader/mcuboot/boot/zephyr

but would not see any mention of it in the compilation log. Does not appear spontaneously in the tree in vscode either

So, I saw that there was already a file called dts.overlay in that dir that was referenced as used in the log, 

So, I edited it.

I noticed that the prj.conf for mcuboot already did set

CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n

so, no need for that.

But after compilation and test, no change. Which I find rather logical, since the bootloader was clearly able to boot and use the 2 pins as a serial port since I can image upload with mcumgr. through these pins.

So, here is the log in "debug"  of mcumgr FOLLOWED by the log of the compilation

FOLLOWED by the whole process that now includes mcu boot log sequence also

nota : today, the image is signed with a private key, but on friday, it was signed with the default key.

I don't expect this to play any role since both situations fail the same way.

==================================

MCU boot logs added : 

just after flashing second build and a reset:

no more displays, even waiting for 5mn

and the J-Link log confirms that we are running the new build

and image list returns

Images:
image=0 slot=0
version: 0.0.0
bootable: true
flags: active
hash: 347abe036d7dd3901fedabebc87b98e35a99b99f85968d71a123a8179c4570e6

Split status: N/A (0)

then image confirm still returns an error 3....
mcumgr --conntype serial --connstring "COM7,baud=115200" image confirm
Error 3......

image list shows still

mcumgr --conntype serial --connstring "COM7,baud=115200" image list
Images:
image=0 slot=0
version: 0.0.0
bootable: true
flags: active

Split status: N/A (0)

so all I can do is a reset, in case ?
but then I see that I reboot on the first original image (oldest date)

and the mcuboot log confirms that we are back at square 1


I hope that you can find with all this information what's wrong

[Jørgen Holmefjord]

Can you post a link to the file that sets:

CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n

in mcuboot? As far as I can see, this is not set by default in the prj.conf file.

Can you also verify that this is set in the built config (from sample directory: build\mcuboot\zephyr\.config). I built a sample with MCUboot for nRF52840 DK, and this is the result:

CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=y
# CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH is not set

[laurentc]

build\mcuboot\zephyr\.config

it does also contain the line.

# CONFIG_CLOCK_CONTROL_LOG_LEVEL_OFF is not set
# CONFIG_CLOCK_CONTROL_LOG_LEVEL_ERR is not set
# CONFIG_CLOCK_CONTROL_LOG_LEVEL_WRN is not set
CONFIG_CLOCK_CONTROL_LOG_LEVEL_INF=y

It could work partially without that set properly ?  

If no, then it looks like a more in depth problem. 

So, How can we proceed so that we find quickly the issue ? 

I can of course remodify the devkit to be in the exact original config...

But that does not look like
