We dont need to add "my additions to work on clean MCU" if we add

CONFIG_MAIN_STACK_SIZE=2048 to prj.conf

I have the same problem. SDK 2.3.0. For me, helped the following:

//////////////////////////

// my additions to work on clean MCU

#include <zephyr/storage/flash_map.h>

//////////////////////////

void main(void)

{

int blink_status = 0;

int err = 0;

//////////////////////////

// my additions to work on clean MCU

if (!device_is_ready(FIXED_PARTITION_DEVICE(storage_partition))) {

printk("Flash device %s is not ready\n", FIXED_PARTITION_DEVICE(storage_partition)->name);

return;

}

Is there any progress on this? We have recently run into exactly these symptoms.

We have a work round that works for development purposes, but I would like a proper fix before rolling out to customers! In our case, switching to V2.0.2 does not solve it.

Thanks,

Phil.

It is related BT_LONG_WQ_STACK_SIZE since the application context can execute and in this stack area. For now this stack size does not seems to be configurable and seems like in some samples there are stack corruptions happening due to insufficient stack size.

Do you know internally what the bug is? If so, can you give me a high level overview? I'm having a hard time seeing the relationship between this issue and the one you posted?

RE: nRF52 DK - Peripheral UART example unmodified fails if CONFIG_BT_SERVICES is enabled.

Susheel Nuguru — Tue, 17 Jan 2023 09:11:59 GMT

Even though the github issue is marked as slate, there are discussions going on internally to address this. We can acknowledge that what you are seeing is something we can reproduce and will fix in the future.

Hi,

We have noticed that this is related to an issue we are tracking in here. Once this is solved, we will include it into the SDK version after the pull is completed.

Hi the_reza and OliverDOM ,

It is great that NCS 2.0.2 works for you. If you don't mind, please stay on that version of the SDK for now.

On my end, I am talking with our R&D about this issue. I will let you know as soon as I got something concrete from them.

Best regards,

Hieu

also verified that the bug is gone with 2.0.2.

RE: nRF52 DK - Peripheral UART example unmodified fails if CONFIG_BT_SERVICES is enabled.

the_reza — Mon, 05 Dec 2022 10:18:38 GMT

So it's a bug in 2.1 that's not there in 2.0? Great - will migrate my code over to 2.0

I've not had a chance to test yet

RE: nRF52 DK - Peripheral UART example unmodified fails if CONFIG_BT_SERVICES is enabled.

OliverDOM — Mon, 05 Dec 2022 10:08:01 GMT

Hi the_reza and Hieu ,
just tested with 2.0.2 and I can't reproduce the behavior.

Best regards

Oliver

RE: nRF52 DK - Peripheral UART example unmodified fails if CONFIG_BT_SERVICES is enabled.

the_reza — Fri, 02 Dec 2022 11:27:35 GMT

Downloading 2.0.2 now. Hopefully it's not hard to migrate the application over. Will test tomorrow.

Hi the_reza and OliverDOM ,

My apology that this ticket was not followed up for a while.

Could you please check if using NCS 2.0.2 can be a workaround for now? It helped droidecaehdron in this thread: peripheral uart sample: connecting causes permanent halting on background threads .

That is not to say that the issue in NCS 2.1.x won't be investigated. It will. But I want to arrange a workaround for you to continue your work as soon as possible.

Best regards,

Hieu

Hieu,

Sorry to hear about the health/family issues. I wish you and your family a speedy recovery.

I'll summarize to try to help. If you install the periperhal uart example and click on the 'erase and flash to board' button, you will get this error. I've traced it down to the problem to some kernel call around a semaphore allocation as it's trying to see what else has been written in the NV ram before it writes the BTLE connection details there. Look at my post in oct 12th with some screenshots to see the traces (i'm not sure how to link to it).

If you run the NV example first, then the code follows a different path as there is stuff in the NV memory and never hit that semaphore code, so it doesn't crash.

Hope that helps.

Reza

OliverDOM — Fri, 02 Dec 2022 07:13:11 GMT

Hi Hieu ,
yes I am using NCS 2.1.1. And as droidecahedron already mentioned 2.1.2 has still the same issue.

And yes, the workaround with nvs example works fine.

Nice to hear that someone is assigned to the ticket. After all, the problem has been known for at least 2 months now. Don't get me wrong, but I am NOT working on student projects here. We are evaluating which BLE SoC will be used for our next generation devices and such a delay does not make the best impressions.

Cheers

Oliver

Hi OliverDOM

Are you using the peripheral UART sample in nRF Connect SDK (NCS) v2.1.x?

Have you tried using NCS v2.0.x? We recently observed a problem where the device enters a reset loop when running NCS 2.1.x, the nRF52833 DK, and the Peripheral UART sample.

When you say you have the same problem, does flashing the NVS sample fix it for you like it did for other people?

Hi the_reza ,

I am recently assigned to this ticket. The symptoms described here are fairly confusing for me. I am partially out of office due to health and family reason. I will return next week and go over everything carefully before following up with you.

the_reza — Fri, 02 Dec 2022 01:40:18 GMT

It's interesting how everyone else seems to have this problem except for the engineers at nordic. Has anyone tried to run this example using the CLI only and not the GUI? I don't think the nordic engineers use the gui...

RE: nRF52 DK - Peripheral UART example unmodified fails if CONFIG_BT_SERVICES is enabled.

OliverDOM — Thu, 01 Dec 2022 10:43:31 GMT

Hi all,
I am using nRF52833 DK and having the same issue. The board is brand new.

Is it planned to be fixed?

In addition I can reproduce the workaround using the nvs example.

But still it is quite annoying.

Cheers

Oliver

(I get this issue with the NCS VS Code IDE!)

RE: nRF52 DK - Peripheral UART example unmodified fails if CONFIG_BT_SERVICES is enabled.

the_reza — Thu, 10 Nov 2022 10:11:21 GMT

If you click on the erase flash button on a used board you also get into this broken state. Are you using the CLI or the visual code IDE? Perhaps it’s related to the IDE?

RE: nRF52 DK - Peripheral UART example unmodified fails if CONFIG_BT_SERVICES is enabled.

droidecahedron — Tue, 08 Nov 2022 22:37:38 GMT

I have this issue as well, but I cannot run "erase board" on the peripheral uart sample or it gets stuck in this state until it gets nvs sample flashed onto it.

RE: nRF52 DK - Peripheral UART example unmodified fails if CONFIG_BT_SERVICES is enabled.

droidecahedron — Tue, 08 Nov 2022 22:36:48 GMT

Running into the same issue with SDK 2.1.2

Once a board is put into this state, I can't get it out.

I put it into this state by erasing the flash then flashing the board.

Another board which is in a working state I flash with the same example and it works just fine.

(nRF52833 DK)

I cannot run "erase board" on the peripheral uart sample or it gets stuck in this state until it gets nvs sample flashed onto it.

Sigurd Hellesvik — Tue, 01 Nov 2022 13:37:42 GMT

Hi Reza,

Thanks for following up on this!
And thanks to you other two to also report this!

I finally got my hands on a new nRF52DK.

But it works for me out of the box.

This is what I did:

Open box with nRF52DK.
Plug into computer
Build nRF Connect SDK v2.0.2 Periperal Uart sample for nRF52dk_nrf52832.
Recovery DK using "nrfjprog -recover"
Flash DK using: "west flash"
Bluetooth example works fine.

You might see that I used the v2.0.2 instead of v2.1.1. This is because I forgot to switch to the newer version when testing.

But can you test with v2.0.2 and see if you see the same issue in that version? It is likely that the same issue will be present in both v2.0.2 and v2.1.1 though.
I also tested with v2.1.1 after, and it works fine then. But NVS might have been initialized at that point. And since it is no way to go back in that case it would "void" the attempt if so.

Regards,
Sigurd Hellesvik

Sigurd Hellesvik I'm confirming that the bug still exists with SDK 2.1.1

E. — Fri, 28 Oct 2022 15:19:46 GMT

Hi,

I had the same issue with the PCA10100 and PCA10040 on the nRF SDK v2.1.0. If I program the nv sample the problem is gone on both boards.

Thnx Reza!
