[GitHub] [mynewt-mcumgr] ErlendWithammerLux opened a new issue #129: Image transfer over uart not bootable
ErlendWithammerLux opened a new issue #129:
URL: https://github.com/apache/mynewt-mcumgr/issues/129
Hello again!
I'm working on transferring images to the nrf52840 by uploading it to nrf9160 and sending it over UART, on the nrf9160dk.
When the image has gone through the 91 it is not bootable however directly uploading it to the 52 works perfectly.
To see if there was a difference between the images I transferred the same image twice to the 52. The first way was using mcumgr upload image to the 52 and swapping it to slot 0, and the second way was transferring to 91 using the same command and then sending it over the uart to slot 1.
When calling mcuboot in the internal shell it lists both images, and they have the same size. Requesting an upgrade prints the error message of "image in slot 1 is not valid" when rebooted.
Looking at the memory on the 52 gave these results which have some differences that might be the cause of the image being invalid.
Another small problem is that only calling mcuboot in the internal shell lists the images, calling mcumgr image list only lists slot 0 after slot 1 being filled over uart. @de-nordic gave a posible reason for this here [https://github.com/apache/mynewt-mcumgr/issues/127](url)
Thanks a lot for any help on this!

Yes. That was supposed to be my next question: whether you confirm the image on the device you upload it to.
The mcumgr does not do that by default, unless the image has been marked as confirmed with imgtool.
The receiving application, on the second mcu, should set the new application it received for test, or confirmed pending; in case when the application will be set for test it needs to confirm itself after reboot (and probably some internal tests).
You may use functions from zephyr/subsys/dfu/boot/mcuboot.c to confirm at run-time.

Good seems the uart transfer is fine, so we have this out of the way.

Yes, i now took a look at the whole first and second slot and they are identical in both the beginning and the end so probably all over
By this i mean slot0 on 52 where i used mcumgr upload img /build/zephyr/app_update.bin directly to 52 and swapped to slot 0.
And slot1 being the same image uploaded the same way to 91 and then transferred over the uart by copying the flash.

Got it to work!
Was missing the tlv which was causing the image to be invalid.
Thanks a lot for the help!

I guess you have nrf9120 dev board, can switch the debug interface (SW10) to nrf52840? you should be able to use nrfjprog tool to dump the memory to binary file.

Are you sure that you are copying right image? The dumps you have shown contain irq vector tables but tables are different it does not seem to be any shift as other fields seem correct.
Can you sign your images adding versions to them and than share the first 512 bytes of bin file, the image headers?

And slot1 (also on 52) being the same image uploaded with mcumgr to 91 and then transferred over the uart by copying the flash.
Some dumps to be sure i didn't do something stupid

Looking at JMemExe this is identical (not quite to the dumps as i have slightly changed the images).
So JMemExe is only reading the nrf9160dk_nrf9160s memory not the 52 so the dumps are indeed wrong.
I will look into reading the rigth memory further.
I am not 100% sure I'm copying the right image. I use img_mgmt_impl_read(1,sent,&data,to_send) to copy it.
The sizes of img91 and img52 are very different, therefore since the read header size is the size of img52 it does seem like the right image is copied.
