08:03 <oter> yoseng I cut/pasted the relevant bits of a LiteDRAMDMAReader example here: https://pastebin.com/Y6cuUAcJ. The bus width etc. (where not generic) are for the ECPIC-5 Lattice board (sorry, don't have yours). It's super naive, but helped me learn. As _florent_ pointed out, love using Litescope to see what's going on. Trigger the example DMA read sequence via a write to the CRG called "output". Any other trigger (button?) would do too.

08:41 <_florent_> somlo: nice for Rocket, VexRiscv-SMP is in fact very similar and the CPU itself is also almost its own SoC

09:57 <Bk> Hi, i have a problem with picorv32.

09:57 <Bk> I load on my fpga the project with interrupt enable

09:58 <Bk> but when an interrupt occours the riscV doesn't enter in a irq function

09:58 <Bk> i loaded the example function with a simple counter inside irq function

10:42 <_florent_> Hi Bk, we would probably need more info about your use case. The default LiteX/PicoRV32 configuration uses interrupts for the UART and seems to be behaves correctly:

10:43 <_florent_> lxsim --cpu-type=picorv32 works correctly while commenting out https://github.com/enjoy-digital/litex/blob/master/litex/soc/cores/cpu/picorv32/core.py#L156 makes it fail

10:45 <Bk> ok, i try to see better this. Another question. How can I load my main file in litex riscV project?

10:46 <Bk> my user case is receive ad interrrupt from external ip

10:47 <Bk> my riscV must be enter in a fuction and print some ip informations

10:48 <Bk> sorry for my bad english

11:33 <_florent_> Bk: is you want to load application code to the CPU, you can have a look at: https://github.com/enjoy-digital/litex/wiki/Load-Application-Code-To-CPU

11:34 <_florent_> if you want a simple example with litex_sim, you can do:

11:34 <_florent_> litex_sim --cpu-type=picorv32

11:34 <_florent_> then

11:34 <_florent_> litex_bare_metal_demo --build-path=build/sim/

11:34 <_florent_> and

11:35 <_florent_> litex_sim --cpu-type=picorv32 --ram-init=demo.bin

11:35 <_florent_> this will create a SoC with PicoRV32 and execute the demo app on it

13:02 <cr1901_modern> how do yo send input to the simulator?

14:42 <_florent_> cr1901_modern: with litex_sim the UART is redirected to the console

14:43 <_florent_> so it's very similar to using the SoC on hardware through a terminal

15:53 <cr1901_modern> Ahhh that's cool. I might be able to dup my USB bug (see privmsg) then...

15:53 <cr1901_modern> _florent_: ^^

22:35 <ethanhs> Hi! Very cool project :)

22:37 <ethanhs> Does anyone know if it is possible to buy a Trellisboard, I've been reading through some of the pcie/ethernet boards litex supports and I'm thinking of getting that or an Acorn
