IAR7.7compile52832ERRS

[justahu]

I USE IAR7.7 AND v11.0

THERE ARE ERRS.

FS_REGISTER_CFG(fs_config_t fs_config) =
	{
		.callback = fs_evt_handler, // Function for event callbacks.
		.num_pages = NUM_PAGES,      // Number of physical flash pages required.
		.priority = 0xFE            // Priority for flash usage.
	};

#define FS_REGISTER_CFG(cfg_var) NRF_SECTION_VARS_ADD(fs_data, cfg_var)

#define NRF_SECTION_VARS_ADD(section_name, type_def) \
    __root type_def @ #section_name
    //__root type_def @ #section_name
#endif

Error[Pa094]: the object attribute "__root" is not allowed here

Error[Ta017]: Auto variable "fs_config @ "fs_data"" cannot be located to section fs_data

help !!!!

thank you

What SDK example are you testing? Where is the "#define NRF_SECTION_VARS_ADD(section_name, type_def) \ __root type_def @ #section_name //__root type_def @ #section_name" ?

HI, I don't know justahu's case but I got same errors with github nrf5-flash-storage-examples (fstorage_example_simple). The link to github example was here: devzone.nordicsemi.com/.../ ....and the solution is?

Hi,

Move the FS_REGISTER_CFG(..) above the fstorage_test() function:

FS_REGISTER_CFG(fs_config_t fs_config) =
{
          .callback  = fs_evt_handler, // Function for event callbacks.
                .num_pages = NUM_PAGES,      // Number of physical flash pages required.
                .priority  = 0xFE            // Priority for flash usage.
};


static void fstorage_test(void)
{
		static uint32_t data;
 .
 .
	

Also replace app_uart.c with app_uart_fifo.c in your project. If you use app_uart.c printf will only print out the first byte (known bug with SDK 11). By adding app_uart_fifo.c you will also need to add app_fifo.c and add the path: Project->Options-> C/C++ Compiler -> Preprocessor tab, and add $PROJ_DIR$\..\..\..\..\..\..\components\libraries\fifo in the include directories list.
