Firmware image size

[fdushin]

Is there any way to expand the size of the "irom0_0_seg" region when building an image?

I am hitting a limit with too much frozen byte code at link time:

Code: Select all

xtensa-lx106-elf-ld: build/firmware.elf section `.irom0.text' will not fit in region `irom0_0_seg'
xtensa-lx106-elf-ld: region `irom0_0_seg' overflowed by 12592 bytes

esp8266.ld seems to have the linker commands for building the image, and it looks like memory is laid out as follows:

Code: Select all

MEMORY
{
    dport0_0_seg : org = 0x3ff00000, len = 0x10
    dram0_0_seg :  org = 0x3ffe8000, len = 0x14000
    iram1_0_seg :  org = 0x40100000, len = 0x8000
    irom0_0_seg :  org = 0x40209000, len = 0x87000
}

Are these values mutable?

I see @pfalcon changed the firmware image size to 0x90000 at 3372f69, and there was a subsequent change to set the start of the file system at 3c9510d.

But I am not sure I understand the math that went into these values.

Thanks!
