Getting "No space in execution region" errors.

[Muhammad Ahmad Shah]

Hi.

I'm trying to declare an uint16_t array while programming on the NRF52 Development kit as follows :

uint16_t FinalSignalArray[225000];

However, I keep getting the following errors:

.\_build\nrf52832_xxaa.axf: Error: L6406E: No space in execution regions with .ANY selector matching main.o(.bss).
.\_build\nrf52832_xxaa.axf: Error: L6406E: No space in execution regions with .ANY selector matching arm_startup_nrf52.o(STACK).

.\_build\nrf52832_xxaa.axf: Error: L6407E: Sections of aggregate size 0x6ff28 bytes could not fit into .ANY selector(s).

What should I do ? Please advise. :(

I am not sure, but that error may occur because that declaration tries to reserve 450kB in RAM, while nRF52 has 64kB RAM.

A 450kB array on a chip with 512kB of flash? Are you sure you're using an appropriate chip for this application? The general use of the nRF series is really to run bluetooth, which you won't be able to do as the bluetooth stack alone takes 112kB out of the 512kB on the chip and you don't have that left.

This is really data which cannot be calculated on the fly, or stored in a much more compressed format?
