I am unable to initialize soft device, but I am able to initialize log, led, gpio and timer as well, I can see debug prints as well. After debugging I found following information. Please help me to solve this problem.
I am using following chip and softdevice:
- nRF51822 REV3
- SDK12.3.0
- S130
- Example code app_ble_uart
- Board PCA10001
MEMORY
{
FLASH (rx) : ORIGIN = 0x1B000, LENGTH = 0x25000
RAM (rwx) : ORIGIN = 0x20001FE8, LENGTH = 0x2018
}
Q1: I want to confirm, as I am using gcc to compile (Not Keil) is following files is the place to change the Stack and Heap size ?
I am setting stack and heap size in \nRF5_SDK_12.3.0_d7731ad\components\toolchain\gcc\gcc_startup_nrf51.S
- Stack_Size, 2048
- Heap_Size, 2048
Q2: I am getting error in following code: The function softdevice_handler_init() returns NRF_ERROR_INVALID_PARAM.
#define SOFTDEVICE_HANDLER_INIT(CLOCK_SOURCE, \
EVT_HANDLER) \
do \
{ \
static uint32_t BLE_EVT_BUFFER[CEIL_DIV(BLE_STACK_EVT_MSG_BUF_SIZE, sizeof(uint32_t))]; \
uint32_t ERR_CODE; \
ERR_CODE = softdevice_handler_init((CLOCK_SOURCE), \
BLE_EVT_BUFFER, \
sizeof(BLE_EVT_BUFFER), \
EVT_HANDLER); \
APP_ERROR_CHECK(ERR_CODE); \
} while (0)

Q3: I am unable to see file name in debug prints! See following code please.
/**
* Function is implemented as weak so that it can be overwritten by custom application error handler
* when needed.
*/
__WEAK void app_error_fault_handler(uint32_t id, uint32_t pc, uint32_t info)
{
static error_info_t * p_error_info;
p_error_info = (error_info_t*)info;
NRF_LOG_ERROR("ID: %d, PC: 0x%X\n\r", id, pc);
NRF_LOG_ERROR("%s (%d): Code 0x%04X %s\n\r",
(uint32_t)p_error_info->p_file_name, p_error_info->line_num,
p_error_info->err_code, (uint32_t)ERR_TO_STR(p_error_info->err_code));
NRF_LOG_FINAL_FLUSH();
// On assert, the system can only recover with a reset.
#ifndef DEBUG
NVIC_SystemReset();
#else
app_error_save_and_stop(id, pc, info);
#endif // DEBUG
}
Q4: Where I can define DEBUG (I am using gcc as mentioned)?
Let me know if any information you need from me.
Thanks
