sd_ble_enable returns NRF_ERROR_NO_MEM

[Tarik]

Hi, I am working on the examples\ble_peripheral\ble_app_uart sdk 12 example on SES.

I was first setting:

FLASH_START=0x1B000
SRAM_START=0x20001EB0

Then tried with app_ram_base value, which is:

FLASH_START=0x1B000
SRAM_START=0x20001FE0

In both cases the function sd_ble_enable returns NRF_ERROR_NO_MEM error.

Any help please.

Thanks

The NRF_ERROR_NO_MEM error can be generated by different things. Are you able to debug and see which specific function that generates the error?

It's returning from: ble_stack_init -> softdevice_enable -> sd_ble_enable

Try FLASH_START=0x1F000 and SRAM_START=0x20002128

@Daniel Wang: with these adresses the program does not even find the starting point

Solved by making sure the values of FLASH_START and SRAM_START are the same as the values in ble_app_uart_gcc_nrf51.ld linker script:

MEMORY
{
  FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000
  RAM (rwx) :  ORIGIN = 0x20001fe8, LENGTH = 0x6018
}

So I just set:

FLASH_START=0x1B000
SRAM_START=0x20001FE8
