Building samples about BLE audio with nrf5340dk does not work #45666

Closed CXsCode closed 2 years ago

CXsCode commented 2 years ago

Describe the bug I built zephyr/samples/broadcast_audio_source and zephyr/samples/unicast_audio_server for nrf5340dk_nrf5340_cpuapp, but the demo prompts an error when running, I think it has something to do with the configuration of zephyr/samples/hci_rpmsg built for nrf5340dk_nrf5340_cpunet.I see in zephyr/samples/hci_rpmsg that in addition to prj.conf there is also nrf5340_cpunet_iso_broadcast.conf and nrf5340_cpunet_iso_receive.conf, but I can't get the sample to work no matter which file I use.

To Reproduce Steps to reproduce the behavior:

  1. west build -b nrf5340dk_nrf5340_cpuapp -d 5340_cpuapp -p auto .\samples\bluetooth\broadcast_audio_source\
  2. west flash -d 5340_cpuapp
  3. west build -p auto -b nrf5340dk_nrf5340_cpunet -d 5340_cpunet -- -DCONF_FILE="E:/zephyr/zephyrproject/zephyr/samples/bluetooth/hci_rpmsg/nrf5340_cpunet_iso_broadcast.conf" .\samples\bluetooth\hci_rpmsg\
  4. west flash -d 5340_cpunet or use default configuration for hci_rpmsg
  5. west build -p auto -b nrf5340dk_nrf5340_cpunet -d 5340_cpunet .\samples\bluetooth\hci_rpmsg\
  6. west flash -d 5340_cpunet

And:

  1. west build -b nrf5340dk_nrf5340_cpuapp -d 5340_cpuapp -p auto .\samples\bluetooth\unicast_audio_server\
  2. west flash -d 5340_cpuapp
  3. west build -p auto -b nrf5340dk_nrf5340_cpunet -d 5340_cpunet -- -DCONF_FILE="E:/zephyr/zephyrproject/zephyr/samples/bluetooth/hci_rpmsg/nrf5340_cpunet_iso_broadcast.conf" .\samples\bluetooth\hci_rpmsg\
  4. west flash -d 5340_cpunet or same as above

Expected behavior Samples running successfully

@CXsCode Please add CONFIG_BT_CTLR_ADV_DATA_LEN_MAX=191 in the nrf5340_cpunet_iso_broadcast.conf file. Relates to #45015

It's useful.But why was it not added to the nrf5340_cpunet_iso_broadcast.conf in 45015, but only to the samples/bluetooth/broadcast_audio_source/boards/nrf52840dk_nrf52840.conf? Although the samples running,but the features of this sample does not seem to be realized. I have two other questions: 1.Does the samples of LE Audio support nrf52840dk? I built a sample(broadcast_audio_sink) for nrf52840dk, but it shows that the broadcast source cannot be searched. Log:

It's useful.But why was it not added to the nrf5340_cpunet_iso_broadcast.conf in 45015, but only to the samples/bluetooth/broadcast_audio_source/boards/nrf52840dk_nrf52840.conf?

I think the dual-CPU setup may be confusing for this case. When you build the cpunet image, that is unrelated to the BT host samples (I think perhaps documentation can improved for this).

For the cpunet you should build something like the /samples/bluetooth/hci_rpmsg/ with CONFIG_BT_CTLR_ADV_DATA_LEN_MAX=191.

For the nr5340 any of the CONFIG_BT_CTLR_* configs will not be present in the BT host samples due to the split architecture

Thalley commented 2 years ago

So perhaps https://github.com/zephyrproject-rtos/zephyr/pull/45015 doesn't solve this issue completely, but may require some additional documentation for the nRF5340, as that isn't obvious.

1.Does the samples of LE Audio support nrf52840dk? I built a sample(broadcast_audio_sink) for nrf52840dk, but it shows that the broadcast source cannot be searched.

The samples work with https://github.com/zephyrproject-rtos/zephyr/pull/45015

2.I built a sample(broadcast_audio_source) for nrf5340dk, after running for a period of time, start printing some errors,and printing stopped after a while. Log:

I'll setup my board to advertise and see if I see the same. Could simply be that the connection between the board and PC broke (have you tried re-attaching it?).

@cvinayak using https://github.com/zephyrproject-rtos/zephyr/pull/45015 and compiling hci_rpmsg on the nRF5340 cpunet with

CONFIG_BT_EXT_ADV=y

CONFIG_BT_CTLR_ISO_TX_BUFFER_SIZE=155
CONFIG_BT_CTLR_ADV_ISO_PDU_LEN_MAX=155

consistently, so it does look like something broke somewhere.

@Thalley what does arm-none-eabi-addr2line -e zephyr/zephyr.elf 0x000144a6 give the file and line number as?

zephyr/lib/libc/minimal/source/string/string.c:337 It's a memcpy failing somewhere.

@Thalley is this still a valid issue and reproducible on latest upstream/main?

Thalley commented 2 years ago

Will need to check once I get the time :)

I cannot reproduce this at the moment, but that might be likely due the host not getting any num_complete_packets back from the controller, thus stalling the TX'ing:

Thanks @Thalley, I will follow up as part of https://github.com/zephyrproject-rtos/zephyr/pull/45989 rework.
