Gap filling in hex files are now disabled per default, and therefore there is no reason to explicitly disable gap filling. It has never been possible to disable gap filling in binary files. Disabling gap filling would just result in the binary file to be gap filled with the tool's default value, objcopy=0x00. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no> |

.. zephyr:code-sample:: code_relocation_nocopy :name: Code relocation nocopy Relocate code, data, or bss sections using a custom linker script. Overview ******** A simple example that demonstrates how relocation of code, data or bss sections using a custom linker script. Differently from the code relocation sample, this sample is relocating the content of the ext_code.c file to a different FLASH section and the code is XIP directly from there without the need to copy / relocate the code. All other code (e.g. main(), Zephyr kernel) stays in the internal flash. nRF5340 DK platform instructions ******************************** The nRF5340 DK has a 64 Mb external flash memory supporting Quad SPI. It is mapped to 0x10000000. To build and flash the application (including the external memory part): .. zephyr-app-commands:: :zephyr-app: samples/application_development/code_relocation_nocopy :board: nrf5340dk/nrf5340/cpuapp :goals: build flash :compact: STM32F769I-Discovery platform instructions ****************************************** The stm32f769i_disco has 64MB of external flash attached via QSPI.
