Hello. We are trying to get arm_blink_leds to work.
We have all the example source code for BBB and BW (fpga).
Anyone made this work? What was your setup? We are using Arachne-pnr, Debian 10.3, yosys 0.8 (I think).
- the shell script doesn’t read back the mem write unless I hack the write flag
- not sure that any electrical signal over gpmc but the BBB does complain with a bus error if the BW isn’t physically there so…
- on the BW side, I think that we’re only seeing write and read signals on start up (which are probably transients on the bus)
