nrf52810 custom board

[pktron]

![image description] hi,

I can able to flash but when i try to debug by putting breakpoints its not coming out of this APP_ERROR_CHECK(err_code) function, attached is the screenshot for the same.

Thanks in advance pavan

(/attachment/53ae4f7b9bc6d98850e47c9c96522853) still its not working i am using below SDK with below path.E:\Nordic\Epigon_latest_code\nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ble_app_uart\pca10040e ..

Attched the gerber details . please suggest if any changes required. Thanks in advance pktron

Hello,

I have designed custom board using nrf52810 but i am unable detect the device in mobile nothing is broadcasting , my setup as below

1. Custom board have only 32MZ crystal . we are using internal oscillator and my code changes for internal clock is as below

//#define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC ,
// .rc_ctiv = 32,
// .rc_temp_ctiv = 2,
// .xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}

please let me know if any changes required?

2. First I am erasing the board completely.

3. flashed the softdevice from this path nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\components\softdevice\s112\hex

4. then flashed the apllication code from this path nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ble_app_uart\pca10040e\s112\arm5_no_packs

when i run the code nothing is advertising in my mobile . please find the attached schematic of my custom for your reference NORDIC BLUETOOTH DESIGN.pdf

thanks pktron

What about to write your own simple FW which has UART debug logging and you place proper debug after each step of initializing things in you code? That would be standard procedure for me (in opposite to guessing from schematics why the FW don't work;)

Make sure that you have removed the DEVELOP_IN_NRF52832 define from the Preprocessor Symbols as this will enable nRF52832 workarounds that are not compatible with the nRF52810.

Also, the rc_ctiv value should be 16 and not 32, i.e.

#define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC,
.rc_ctiv = 16,
.rc_temp_ctiv = 2,
.xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}

Are you able to debug the application?

[bjorn-spockeli]

Have you applied the changes I suggested in my first comment?

Hi,

Its working fine after changing my crystal load capacitor value to 22pf..
