Why does make hello.prog use iceprog after running make ARTY.firmware_config? #98

Closed JamesTimothyMeech closed 1 year ago

JamesTimothyMeech commented 1 year ago

In the Makefile iceprog used to program the arty when running make hello.prog after running make ARTY.firmware_config

we get this:

init..
cdone: high
reset..
cdone: high
Extended Device String Length is 0xFF, this is likely a read error. Ignoring...
flash ID: 0xFF 0xFF 0xFF 0xFF
file size: 13872
erase 64kB sector at 0x020000..

because this snippet from the makefile uses iceprog

# Sends the generated executable in flat binary form to SPI flash
%.prog: %.spiflash.bin
        iceprog -o 128k $<

Am I right in thinking that iceprog is the wrong tool for the job here?

It seems that the best way to load programs onto FemtoRV is to follow the instructions in the LiteX tutorials in this repo
