Adapting NRF52832 example to custom board with NRF52810

[cory123]

My custom board with NRF52810 is done and I'm now trying to get some examples working. I am adapting blinky_s132 in SES. To do this I edited the project options including disabling the FPU, defining BOARD_CUSTOM, chaning the device definition to NRF52810_XXAA, and some other changes. I've attached the SES project file. I also opened this project file in a text editor and changed  ...

arm_target_device_name="nRF52810_xxAA"

I also created a custom_board.h which I have attached. The program compiles correctly and programs fine but when debugging it seems to get stuck in a trap. I don't think SES has registered that I'm using 52810 instead of 52832 as can be seem by the flash and ram usage. Can you help me resolve this?

By the way, I can't seem to upload more than one file for some reason.

I'm still having problems with my NRF52810 board. I can run non-softdevice examples fine. Here are the steps I'm taking to get the ble_app_gatts_c_pca10040e project working in SES.

1. open this project in SES.

2. Change project options for "common" config.. Preproccesor macros set to

APP_TIMER_V2

APP_TIMER_V2_RTC1_ENABLED

BOARD_CUSTOM

CONFIG_GPIO_AS_PINRESET

FLOAT_ABI_SOFT

INITIALIZE_USER_SECTIONS

NO_VTOR_CONFIG

NRF52810_XXAA

NRF52_PAN_74

NRF_SD_BLE_API_VERSION=7

S112

SOFTDEVICE_PRESENT

3. created custom_board.c by copying board_pca10040.c and removing defines that do not apply.

4. Comment out contents of buttons_leds_init() function in main.c because I have no buttons on my board.

5. Open nrfGo Studio, program s112 softdevice followed by the new project hex file. I've tried both the "Debug" and "release" without success. If I attache the debugger, reset and then pause the program, I always end up at the same instruction:

4770        bx lr

I've attached a screen cap of that program location I get trapped in. Can you see any mistake I'm making?

Hi,

 Do you use the same setting in Setp.2 & 3? 

Please start a terminal emulator like PuTTY and connect to the used COM port with the following UART settings and provide the log:

• Baud rate: 115.200
• 8 data bits
• 1 stop bit
• No parity
• HW flow control: None

I am using the same custom_board.h in both projects. Here is the preprocessor macros from my blinky project:

BOARD_CUSTOM
BSP_DEFINES_ONLY
CONFIG_GPIO_AS_PINRESET
FLOAT_ABI_SOFT
INITIALIZE_USER_SECTIONS
NO_VTOR_CONFIG
NRF52810_XXAA
NRF52_PAN_74

And is the preprocessor macros for the BLE GATTS example:

APP_TIMER_V2

APP_TIMER_V2_RTC1_ENABLED

BOARD_CUSTOM

CONFIG_GPIO_AS_PINRESET

FLOAT_ABI_SOFT

INITIALIZE_USER_SECTIONS

NO_VTOR_CONFIG

NRF52810_XXAA

NRF52_PAN_74

NRF_SD_BLE_API_VERSION=7

S112

SOFTDEVICE_PRESENT

The only differences I see are...

APP_TIMER_V2

APP_TIMER_V2_RTC1_ENABLED

BSP_DEFINES_ONLY

NRF_SD_BLE_API_VERSION=7

S112

SOFTDEVICE_PRESENT

I don't have a serial port on my NRF52810 board. Do you mean an emulated serial port over the debugger or a physical serial port?

Hi, 

Could you enable the RTT log in the sdk_config.h as follwing and provide it?

//==========================================================
// <e> NRF_LOG_BACKEND_RTT_ENABLED - nrf_log_backend_rtt - Log RTT backend
//==========================================================
#ifndef NRF_LOG_BACKEND_RTT_ENABLED
#define NRF_LOG_BACKEND_RTT_ENABLED 1
#endif

It will show in the Segger.

I enabled RTT as suggested and also disabled deferred logging with...

NRF_LOG_DEFERRED=0

I can now see RTT output from this I added in main.c .....

NRF_LOG_WARNING("hello you\n");

I am getting no RTT output from the SoftDevice or any other RTT output at all. When the SVCALL(SD_SOFTDEVICE_ENABLE ...) is called the program runs until it gets trapped (see screencap). Am I programming the SoftDevice incorrectly? I'm can't seem to figure this one out!
