Quick feather region rom overflow

As picture attached, rom size is not enough after adding some sensor drivers. How to add more space in rom region? I found quickfeather.ld in GCC_Project folder and the origin for ROM section is 0x00. As my understanding, 0x00 is for bootloader and 0x80000 is for m4app. Is quickfeather.ld the right file for qf_ssi_ai_app?
MEMORY
{
rom (rx) : ORIGIN = 0x00000000, LENGTH = 0x0002C000
ram (rwx) : ORIGIN = 0x2002C000, LENGTH = 0x0003c800
spiram (rw) : ORIGIN = 0x20063800, LENGTH = 0x0000800
HWA (rw) : ORIGIN = 0x20064000, LENGTH = 0x00018000
shm : ORIGIN = 0x2007C000, LENGTH = 0x00004000
}
BTW, should we modify tinyfpga-programmer-gui.py to meet the changes of rom region in .ld file?

It works after change the rom length and modify the origin address for the other section in quickfeather.ld.
MEMORY
{
rom (rx) : ORIGIN = 0x00000000, LENGTH = 0x00040000
ram (rwx) : ORIGIN = 0x20040000, LENGTH = 0x0003c800
spiram (rw) : ORIGIN = 0x2007c800, LENGTH = 0x0000800
HWA (rw) : ORIGIN = 0x2007d000, LENGTH = 0x00018000
shm : ORIGIN = 0x20095000, LENGTH = 0x00004000
}

Many thanks for that solution.

Thanks for the tip — changing the ROM length and origin address did the trick! Just to clarify: is there a recommended way to calculate safe values for other sections like `spiram` or `HWA` if usage increases?

Hey, thanks for sharing this! I've bumped into similar ROM size issues when trying to cram in extra features. Modifying the quickfeather.ld file seems like the right approach for the qf_ssi_ai_app. Just double-check that shifting the ROM origin won't clash with the bootloader's critical functions, maybe similar to when you're trying to nail a tricky jump in a game like
Snow Rider 3D. And yeah, updating tinyfpga-programmer-gui.py to reflect the new ROM region definition in the .ld file is likely essential for proper flashing. Good luck!
