tcal@danielyou -- about LEDs on the Arty board for the Antmicro TFLite demo.   Start with litex-buildenv/build/arty*/software/include/generated/csr.h (after you've built gateware).  It will define a macro "cas_leds_out_write(unsigned char value)".   It uses "csr_writel()" which is defined in litex-buildenv/third_party/litex/litex/soc/software/include/hw/common.h.    You can probably just cut out those macros/inlines and put17:28
tcalthem in your C program.    (Access to the RGB LEDs is not generated by default, but it can be turned on.)    NOTE: this applies to the Antmicro fork of litex-buildenv pinned to November 2019, which is what is used by the demo.17:28

pepijndevosAh, it's a special thing for ULX3S with a very broken makefile -.-18:53
daveshahThere is a newer version called fujprog that might be easier to build19:06
daveshahBut openFPGloader is probably the way to go for ULX3S19:06
