#pragma arm section as compiler command line arg

Ed Theobald

I can use the following #pragma in my code to put variables into my own data section:
#pragma arm section rwdata = "__my_data_block__"

Is it possible to do this as a compiler option so that I can have a whole group of files compiled thusly?

The reason I want to do this is so that I can compile a whole group of 'off the shelf' library files without having to edit them to add the #pragma.

Thanks for any help.

    Thanks! That did the trick.

    So in the scatter file I add something like:

    __bluetooth_library_block__ +0 ALIGN 0x80 { ble_event.o (.data, .bss) ble_gap_address_get.o (.data, .bss) ble_gap_address_set.o (.data, .bss) ble_gap_adv_data_set.o (.data, .bss) ble_gap_adv_start.o (.data, .bss) ble_gap_adv_stop.o (.data, .bss) ble_gap_app.o (.data, .bss) ble_gap_appearance_get.o (.data, .bss) ble_gap_appearance_set.o (.data, .bss) ble_gap_auth_key_reply.o (.data, .bss) ble_gap_authenticate.o (.data, .bss) }

    ... and this places all ram data from these modules into the same block named __Bluetooth_library_block__.

    Now I can setup the MPU to allow task 'X' access to this block.

    Thanks again!
