17:28 <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 put

17:28 <tcal> them 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.

17:47 <pepijndevos> Is this still correct? https://github.com/gojimmypi/ulx3s-toolchain/blob/master/soft_cpu.sh

18:34 <pepijndevos> What is ujprog part of?

18:53 <pepijndevos> Ah, it's a special thing for ULX3S with a very broken makefile -.-

19:06 <daveshah> There is a newer version called fujprog that might be easier to build

19:06 <daveshah> But openFPGloader is probably the way to go for ULX3S
