Huge binaries after objcopy

[simonsilvalauinger]

Hi there,
thank you for creating this small project as help to start a rust project. on longan-nano.
Unfortunatelly I have a problem with objcopy trying to use the dfu-util method. Using riscv-nuclei-elf-objcopy -O binary target/riscv32imac-unknown-none-elf/release/examples/blinky blinky.bin results in an 385M sized file! Any other example has a similar result file size.
Does somebody has a clue how to solve this behaviour?

Thank you
Simon

You can try beta or nightly compiler to solve the issue. See also: icebreaker-fpga/icebreaker-litex-examples#6 (comment)
