GDB Load Failed Due to Invalid memory.x Flash Layout #102
Description
Description
In the Hardware > Configuring section of the Rust Embedded Book, the FLASH : ORIGIN value is set to 0x08000000. However in the memory.x file, the value is set to 0x00000000.
Line 6 in 18bb680
This is a very subtle difference but leads to the following error:
$ arm-none-eabi-gdb -q target/thumbv7em-none-eabihf/debug/examples/hello

This was pointed out in a Reddit Post last year.
