Log + Utilities

Reload the FPGA configuration from flash (needs a connection).

Reads the FPGA flash back to identify the installed build. Briefly blanks + reloads the FPGA; writes nothing.

Read the whole 1 MiB config flash over JTAG and save it (chromatic_flash_dump.bin). Briefly blanks + reloads the FPGA; writes nothing.
