I have the same problem of getting

E: Endpoint binding failed with -11

Any clue on it ??

Thanks,

hi，

how to flash to cpunet?
Build for real_ board_ cpunet?
I'm new to learning nrf5340dk.

why are you testing this with v1.9.99? That is not a release version. We have NCSv2.0 released.

Also my side of the VSC window looks a bit different than yours.

So please update your Visual code studio and nrf extensions along with your NCS release.

Your issue seems to be in zephyr\drivers\bluetooth\hci\rpmsg.c where bt_rpmsg_open is unable to take the semaphore ipc_bound_sem. I have not seen this before, and if you use latest VSC and NCS version, then we can try to investigate it with similar tools and SDK setup.

it's default codes, runing to 5340DK well.

what are the configurations you used to flash into the network core? The bluetooth examples needs hci_prmsg to be flashed into network core. If you have used the right board and right configuration, then a child image should be flashed into the network core along with the peripheral uart being flashed into the application core. It looks to me that network core has not been flashed.

Hi,

thanks for reply,

Helloword and uart work well,

but bt_enable error,

use the same source code,DK work well,

I think the hardware problem, but i have no idea.

Best regards

should have worked out of the box if your hardware is setup right, cannot see anything obviously wrong in your schematics aswell. Are you able to run any other samples apart from peripheral uart?
