[BUG] <nuttx:nrf52840_dk:sdc_nimble issue. >

[zhihui2015]

Description / Steps to reproduce the issue

1. The project version used is NuttX-12.6.0, and the compiler version is arm-none-eabi-gcc (Arm GNU Toolchain 13.2.rel1 (Build arm-13.7)) 13.2.1 20231009
2. Execute ./tools/configure.sh -l nrf52840-dk:sdc_nimble
3. Execute make, sdk-nrfxlib will be downloaded in the process, and the nuttx.bin will be generated
4. nuttx.bin the burning is performed, it is found that it cannot be burned, and after analysis, it is found that the size of the nuttx.bin is 536871168, which is the abnormal size
5. Open the nuttx.bin with jflash, and find that most of the back is 0, which should be an exception to the construction, and the back should be useless. After truncate -s 512K nuttx.bin truncate and then burn again, i can burn normally.
6. Restart after burning, and print as follows
   nx_mount: ERROR: target /proc exists and is a special node
   ERROR: Failed to mount the PROC filesystem: -20
   ERROR: nrf52_sdc_initialize() failed: -1

NuttShell (NSH) NuttX-12.6.0

Why is that? Do I need to download a separate softdevice controller, such as the S140? Or does nuttx.bin already include a softdevice controller? I'm not sure.

On which OS does this issue occur?

I haven't seen this before because I always use nuttx (elf file) or nuttx.hex.

nuttx.bin it is huuuuge which doesn't look good:

-rwxr-xr-x  1 raiden00 raiden00 513M Feb  8 08:08 nuttx.bin

Why is that? Do I need to download a separate softdevice controller, such as the S140? Or does nuttx.bin already include a softdevice controller? I'm not sure.

all is done automatically. nuttx.bin seems broken, try with nuttx or nuttx.hex.

nrf52840-dk:nsh configuration is normal size:

-rwxr-xr-x  1 raiden00 raiden00  80K Feb  8 08:18 nuttx.bin*

so the soft device support breaks something in nuttx.bin generation. The same issue is with cmake build

@raiden00pl Thanks for your reply!

With nuttx(elf), I can successfully flash using J-Link. After flashing, the log output is as follows:

ABCDE▒nx_mount: found procfs  
bt_initialize: btdev 0x200007e4  
SoftDevice Controller initialized  
NRF52 Bringup complete  
btnet_ifup: Bringing up: 00:00:00:00:00:00

NuttShell (NSH) NuttX-12.6.0  
nsh> hci_tx_kthread: started  
hci_tx_kthread: HCI TX thread started  

Has NimBLE started running normally? However, I cannot find any BLE advertisements using nRF Connect.

I tried entering nimble in NSH, and the system executed nimble_main. I also added print logs in nimble_main, and they were successfully printed, which indicates that the system has loaded nimble_main correctly. However, I still cannot find the BLE advertisement in nRF Connect, and I am not sure why.

Could you share your test steps with me?

[raiden00pl]

I confirm that it doesn't work with release 12.6, but it works with 12.7 and 12.8. Master branch is also broken

[raiden00pl]

master is broken by this commit 620f4bc #15237

[hujun260]

OK

[hujun260]

Please help me verify this pr.
#15797

Thanks for the reply! @raiden00pl I switched to 12.6-RC1, or 12.8, and the tests are all fine. I can now detect BLE advertisements and establish connections using nrf-connect. Both 12.6 and master versions have issues.

@hujun260 I cherry-picked this PR-15797, and it seems mostly fine. BLE advertisements work during testing, but I see the following log during startup:

nsh> nimble
GAP procedure initiated: stop advertising.
Failed to restore IRKs from store; status=8
advertise

Not sure if there are any other issues?

If you revert 620f4bc, will there still be problems?

[raiden00pl]

Failed to restore IRKs from store; status=8

This message is expected.
