Failed to reset CS47L63

[Zhongsan]

Hi,

Failed to reset CS47L63 when swapping the role,

if use the configuration like this:

[
{
"nrf5340_audio_dk_snr": 1050140236,
"nrf5340_audio_dk_dev": "headset",
"channel": "left"
},
{
"nrf5340_audio_dk_snr": 1050167579,
"nrf5340_audio_dk_dev": "gateway",
"channel": "NA"
},
{
"nrf5340_audio_dk_snr": 1000,
"nrf5340_audio_dk_dev": "headset",
"channel": "right"
}
]

everything is fine

if swapping the role like this:

[
{
"nrf5340_audio_dk_snr": 1050167579,
"nrf5340_audio_dk_dev": "headset",
"channel": "left"
},
{
"nrf5340_audio_dk_snr": 1050140236,
"nrf5340_audio_dk_dev": "gateway",
"channel": "NA"
},
{
"nrf5340_audio_dk_snr": 1000,
"nrf5340_audio_dk_dev": "headset",
"channel": "right"
}
]

will be failed:

why? Is the DK broken?

Hi,

I would need to have some additional information.
1. Could you provide more information about your setup? Which devices do you use and how are they connected?
2. Do you use unmodified nRF5340 audio sample?
3. Could you please provide more information about the issue? When did it happen first? Did it work well before the error appeared? If it did, for how long?
4. Could you try swapping the lines in nrf5340_audio_dk_devices.json configuration file several times? What is the result? Does it fail consistently when you change configuration?
5. Do you build using script or command line? Please provide the steps that you use for building.

Best regards,
Dejan

Hi, Dejans

for Q1, the steps;

1.edit prj.conf, add following config:

##############################
CONFIG_BT_DEBUG_LOG=y
CONFIG_DEBUG_INFO=y
CONFIG_BT_LOG_LEVEL_WRN=y
#########################
CONFIG_SW_CODEC_SBC=n
CONFIG_SW_CODEC_LC3=y

CONFIG_AUDIO_SOURCE_USB=y
CONFIG_AUDIO_SOURCE_I2S=n

CONFIG_TRANSPORT_CIS=y
CONFIG_TRANSPORT_BIS=n

CONFIG_LOG_MAIN_LEVEL=4
CONFIG_LOG_AUDIO_CODEC_LEVEL=4
CONFIG_LOG_AUDIO_DATAPATH_LEVEL=4
CONFIG_LOG_AUDIO_SYNC_TIMER_LEVEL=4
CONFIG_LOG_STREAMCTRL_LEVEL=4
CONFIG_LOG_BLE_LEVEL=4
#CONFIG_LOG_AUDIO_SERVICES_LEVEL=4
CONFIG_LOG_CS47L63_LEVEL=4
CONFIG_LOG_CTRL_EVENTS_LEVEL=4
CONFIG_LOG_I2S_LEVEL=4
CONFIG_LOG_AUDIO_USB_LEVEL=4
CONFIG_LOG_BUTTON_HANDLER_LEVEL=4
CONFIG_LOG_HW_CODEC_LEVEL=4
CONFIG_LOG_LED_LEVEL=4
CONFIG_LOG_PMIC_LEVEL=4
CONFIG_LOG_POWER_MODULE_LEVEL=4
CONFIG_LOG_SD_CARD_LEVEL=4
CONFIG_LOG_BOARD_VERSION_LEVEL=4
CONFIG_LOG_DEFAULT_LEVEL=4

2.  edit nrf5340_audio_dk_devices.json to match the Nrf5340 Aduio DK, like previous mentioned;

3. use two usb cables to connect two Nrf5340 Audio DK with the laptop

3. build the project by bash cmd: python buildprog.py -c both -b debug -d both -p

Q2. just edit the prj.conf for debug message

Q3. we got the nrf5340 audio dk for several days, it is the first time of this issue appeare, and first time to swap the role

Q4. after swapping the role for several times, this issue was gone, but Not sure if it's permanent

Q5. build the project by bash cmd: python buildprog.py -c both -b debug -d both -p

BR,

Zhongsan

Hi Zhongsan,

You should have the battery included in the package with nRF53 audio dk board. Please try using that battery.

Could you provide a log that shows the error? Is error present when you connect the battery?

Best regards,
Dejan

[Zhongsan]

Hi, Dejans

sorry for too late to reply

we dont have any battery or NFC attena in anti-static package

thanks

[dejans]

Hi Zhongsan,

The battery is included in the cardboard box together with the board, but outside of anti-static package.

Best regards,
Dejan

[Zhongsan]

Hi, Dejans

yes, but we dont receive that, i dont know what happened, and already send a email to the distributor

BR

thanks

[dejans]

Hi Zhongsan,

I hope that you will get the battery soon.

Best regards,
Dejan

I was having similar issues as Zhongsan  - here is the information asked of him in this thread but pertaining to my situation (in case anyone in the future comes along to find this):

• Board Specs:
  • PCA10121
  • 1.0.0
  • 2022.20
• The board that was showing this behavior has modified antenna we're experimenting with (not sure the PN or anything)
• I've enabled 'CONFIG_AUDIO_SOURCE_I2S' and 'CONFIG_STREAM_BIDIRECTIONAL' in prj.conf
  • I have tried some other options but this is what I currently have and did not record the others
• Building & Programming with buildprog.py
• I've added debug prints to try and diagnose this before finding this thread - removing them has no effect.

I was originally testing with only USB providing power; when I plugged the battery into the board giving me trouble a simple power cycle "solved" the issue.

Is it known why having the battery power impacts this (and presumably other things)? It would be nice to know and be able to account for with future development.

Hi,

It was known issue where PMIC failed to start CS47L63 chip and battery helped in this process. This issue was fixed in later versions.
