IAR nrf52832_xxab.icf error

[jsleeman]

Hello,

I noticed the linker file we were using was for the nRF52832_xxAA so I got the nrf52832_xxab.icf from C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.0\arm\config\linker\NordicSemi\nrf52832_xxab.icf.

After switching linker files IAR fails the linking stage with the following error: Error[Lc041]: "block PROC_STACK" defined but not referenced nrf52832_xxab.icf 74

The new linker file: nrf52832_xxab.icf

Are the linked files included with IAR correct?

Look forward to hearing from you, James

If you are using the SoftDevice, then I would recommend using the ble_app_uart_iar_nRF5x.icf from the SDK version you are using. The only thing that changes between the .icf files for the ble_peripheral examples is the ram starting address. The total RAM is always the same(end: 0x2000ffff), but the RAM start address for where your application should start depends on how much RAM the SoftDevice uses. This changes based on how many services, characteristics, links, etc you configure the SoftDevice to use.

The sd_ble_enable function, which is used to enable the SoftDevice, will return the minimum start address of the application RAM region required by the SoftDevice for the given configuration in the app_ram_base variable. The value of app_ram_base will be printed on the UART/RTT if you have logging enabled. You can also open a debug session, set a breakpoint after the in softdevice_enable(ble_enable_params_t

• p_ble_enable_params) function in softdevice_handler.c and examine the value of app_ram_base that way.

I recommend taking a look at how one of the examples in the SDK, and see how the IAR project is configured.
