I think I was missing "-C", "link-arg=-Tesp32_rom_functions.x",?

[target.xtensa-esp32-none-elf]
runner = "espflash --monitor /dev/tty.usbserial-02728E37 --monitor-speed 115200"

[build]
rustflags = [
  "-C", "link-arg=-nostartfiles",
  "-C", "link-arg=-Wl,-Tlinkall.x",
  "-C", "link-arg=-Tesp32_rom_functions.x",
]
target = "xtensa-esp32-none-elf"
