Allows creating binaries using an existing binary type & linker script, but with modified RAM/SCRATCH addresses For example, to only use SRAM1 so you can power down SRAM0 in your binary you could use `pico_set_modified_binary_type(<my_exe> no_flash RAM "0x20040000" "256k"`

this is useful functionality; we need to think about whether this is best as modifying the linker script or injecting as per FLASH_SIZE (either way it should - and i think it is for FLASH_SIZE be modifiable via linker script) |
Perhaps it would be nice if you could use symbolic aliases here, rather than having to use hardcoded addresses? 🤷 |

Maybe this is a first step towards #1547 ? |

This adds a function to create binaries using an existing binary type & linker script, but with modified RAM/SCRATCH addresses
A similar function is already in use by the encrypted bootloader example, and picotool xip_ram_perms binary, so this extends those by adding scratch address modification
For example, to only use SRAM1 so you can power down SRAM0 in your binary you could use
To create a XIP_SRAM only binary you could use
pico_set_modified_binary_type(<my_exe> no_flash RAM "0x13ffc000" "12k" SCRATCH_X "0x13fff000" "2k" SCRATCH_Y "0x13fff800" "2k")The existing
memmap_blocked_ram.ldcould be created using
