| xobs | tcal: yes, that works just fine. | 01:01 |

| xobs | The program "foboot" is stored entirely within the boot rom. When you run a riscv program, the boot rom is still there, it just jumps to your program. | 01:08 |
| xobs | If you want to test a new Peripheral, you can do something like loading your test program to ram instead of spi flash. That way your new bitstream will still be there after you reboot, if you run dfu-util -e | 01:09 |

| tcal | xobs: Thanks! Is putting the entire test program into RAM done with the linker.ld config? Or is it better to use `__attribute__((section(".ramtext")))` in the code? I also see the `--dfuse-address` option to dfu-util...hmm, this is the first I've heard of DfuSe, that's a bit confusing. | 04:54 |
| xobs | I'm not sure what `dfuse` is. I don' see it mentioned in the spec at all... | 06:27 |

| tnt | DfuSe is a propriatary DFU extension for ST micros | 06:38 |
