Can not upload HEX file

[edgars.dev]

Hello!

Thanks for your help last time, highly appreciated.

However I haven't got till actuall programming because now I can't upload hex files. I start Thingy:91 in boot mode, connect, press write and it immidiately goes in application mode and programmer sofware throws error that I have to check that it is in boot mode. I have no clue how to fix this. Any hints?

Edit: This videoplayer seems to be out of order. Uploaded video to youtube.

Kind regards!

Hello,

Thanks for your help last time, highly appreciated.

No problem at all, we are here to help!

However I haven't got till actuall programming because now I can't upload hex files. I start Thingy:91 in boot mode, connect, press write and it immidiately goes in application mode and programmer sofware throws error that I have to check that it is in boot mode. I have no clue how to fix this. Any hints?

I am sure you have seen the programming applications through USB ( MCUBoot ) guide, but I link it here just in case.
To verify if the issue is with the .hex used, or nRF Connect desktop application, could you go ahead and download the latest firmware from this site, and follow the programming applications guide to program the thingy91_ltem_dfu_2020-04-29_bc7ade8b.hex from the downloaded zip folder?
Please let me know if this works, or if you are encountering the same issue when doing this.

For the record, could you also tell me which NCS version you are working with?

Best regards,
Karl

Yes. Did everything exactly as it was told in instruction. Problem is that when I press Write button it immidiately resets MCU and after that it goes in to application mode (LEDs fade in) It doesn't even matter what hex file I provide.

v0.5, the one that I had hard time to set up and now it compiles hex. Anyhow. I don't see how it is related.

Programmer is v1.4.2

Ok, thanks, I will.

Great, the readability is highly increased already, thank you.

Tried one that my friend compiled and succesfully uploaded with his computer to the same thingy device.

When you say "the same thingy device", do you mean your friend's own thingy91, or the physically same device as you are having trouble with?
In case of the latter, I would recommend reinstalling your nRF Connect.

Have you updated your device to the most recent modem firmware, since you got it?
The process is described in the Updating Thingy:91 Firmware section.

Furthermore, could you elaborate what you meant with this comment?

Looking forward to solving this issue together,

See my previous post. https://devzone.nordicsemi.com/f/nordic-q-a/61872/problem-with-setting-up-segger-on-mac 
Now it is compiling.

By this, do you mean that your original issue is resolved - that you are now able to program your thingy 91 using the nRF Connect Programmer?
If so, was this resolved by updating the firmware of your device?
I am asking for future reference, if someone else should encounter the same issue.

Best regards,
Karl

Noo, not at all. I solved compiling issue in previous post. Now I am trying to solve hex write to mcu issue. Just answering your questions.

[Karl Ylvisaker]

This is what you would have thought, I just wanted to make sure.

Could you answer the other questions I raised earlier also:
