Programming MS12SF1 module

[Rakshita]

I am trying to program MS12SF1 module through nrf5340DK. I tested the blinky code to toggle the LED pins but while checking through oscilloscope the pins showed nothing, wasn't toggling.

Have just connected 4 programming pins - Vdd, GND, SWDIO, SWCLK. The module is programming but somehow I am not able to see the led pins getting toggled.

It would be grateful if someone can help me with this.

Hello,

You can see the toggle on the module but while checking though Oscilloscope, there was no output on those pins?

''Have just connected 4 programming pins - Vdd, GND, SWDIO, SWCLK.'' - could you please explain this by showing the setup picture?

These are the default pins from default device tree file from nrf board (nrf7001dk_nrf5340):-

what is the pin numbers of LED for your module and did you check if it is overlapped with any other pins specified for other peripheral?

No no the module is connected with nrf5340dk so the build configurations which I set was nrf5340dk_nrf5340_cpuapp
The module was programmed with the blinky code
It does have some different pinout as compared to nrf5340 but not able to find out that which pin than represents what

Can I see your setup as I asked in my previous reply? I would like to see how you programed the module using P20 pin of nRF5340?

''It does have some different pinout as compared to nrf5340 but not able to find out that which pin than represents what'' Can you please send the schematic of your module?

Did not program it using P20 pin

I added the internal clock configuration so atleast the blinky and button sample code works fine
But when I tried programming peripheral_lbs code to connect with bluetooth, the led which should get ON when bluetooth gets connected but bluetooth doesn't even advertises but the led switches ON.

How is that possible?

Hello Rakshita,

One of the reasons for not advertising by the peripheral is If no high frequency crystal is not mounted on the board/module. Do you have 32 MHz crystal on the module?

Hi I had the same problem, I'm using an MS12SF1 and running the blink example from SDK 2.6.1 to be successful I had to add the following settings in project.conf:

CONFIG_GPIO=y

# Enable Zephyr's clock management

CONFIG_CLOCK_CONTROL=y

# Sets the HF (High Frequency) clock source

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_50PPM=y

# Sets the LF (Low Frequency) clock source

CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y

# Other clock settings that may be required

CONFIG_CLOCK_CONTROL_NRF_K32SRC_500PPM=y

But this is low frequency, the   MS12SF1  has  nRF7002+nRF5340 WiFi 6+BLE 5.3, I'll need high frequency, how can I enable this in the zephyr?  Especially in project.conf

So can I run all the nordic examples (bluetoot, wifi, provisioning) using the NRF53's internal clock at high speeds?

Hello,

Could you please open a new case describing your issue?
