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 E: HCI driver open failed (-11)
What's wrong with code -11?
Best regards
