NCS HCI driver open failed (-11)

[yoyou]

Hello,

nRF5340,NCS1.9.99,

32MHz and 32.768KHz oscillator had exchange with 5340DK, 5340DK work well.

\v1.9.99\nrf\samples\bluetooth\peripheral_uart

    int err = bt_enable(NULL);

    if (err) {

        error();

    }

 

my hardware got error: HCI driver open failed (-11)

*** Booting Zephyr OS build v2.7.99-ncs1-2212-g038a2de883a0  ***
Starting Nordic UART service example
I: 2 Sectors of 4096 bytes
I: alloc wra: 0, fe8
I: data wra: 0, 0
E: Endpoint binding failed with -11

What's wrong with code -11？

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

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

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.

hi，

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