How to use a board specific linker script without modifying platform.txt #2307
-
|
I'm using a custom variant of rp2040 and I want to have project specific custom linker scripts for it. Right now im modifying the memmap_default in the lib folder. I see that boards have a line myboard.build.ldscript=memmap_default.ld but I cant seem to find where it's taken into account in the build process. When I look at platform.txt all I see is that its hardcoded to the one in /lib. Is it possible and am I wrong? |

I was planning on enabling it through that boards.txt entry. But, since every RP2040 board has the same memmap and no external SRAM/etc. that the linker needs to worry about, I never got around to it. Right now editing Note that OTA, core, filesystems/EEPROM, and final link stages assume certain things about the layout and if you drop things or rearrange them it might not work too well. |

platform.txtlike you're doing is the only way. It should be cleaned up eventually, I suppose...Note that OTA, core, filesystems/EEPROM, and final link stages assume certain things about the layout and if you drop things or rearrange them it might not work too well.
