<rjo> Bachir: Hi
<Bachir> May I ask you a question ?
<Bachir> concerning the Direct Memory Access of the doc
<Bachir> * The example of the Direct Memory Access of the doc
<rjo> Don't ask to ask. Just ask.
<Bachir> '=D
<Bachir> I try to do the example of the dma
<Bachir> the lowest pulse and delay i can do is 170 ns
<Bachir> is it normal ?
<rjo> Depends. You'll have to describe in detail what you are doing.
<Bachir> I copy paste the example of the doc https://m-labs.hk/artiq/manual-beta.pdf
<Bachir> in page 32 chapter 6.6
<Bachir> I just change "ttl0" to "ttl4"
<Bachir> but I will read the link you gave me
<rjo> there is no page 32 in chapter 6.6
<rjo> page 32 has three examples
<Bachir> page 33 sorry
<rjo> I would suspect that you are seeing sustained throughput limitations. (as in #946)
<rjo> In general there is no problem generating pulses much shorter (as short as 8 ns if you want and 1 ns if you tweak the timing). Just not sustained.
<rjo> If you need higher sustained rates, there are several suggestions in that issue.
<Bachir> I try to comment #[cfg(has_rtio_analyzer)]- io.spawn(4096, analyzer::thread); of the artiq/firmware/runtime/main.rs file
<Bachir> but it is the same thing
<rjo> and did you compile and flash that firmware after editing?
<Bachir> no ...
futarisIRCcloud has quit [Quit: Connection closed for inactivity]
<Bachir> And how do I compile and flash it ?
mumptai_ has quit [Quit: Verlassend]
mumptai has joined #m-labs
<Bachir> is it python -m artiq.gateware.targets.kasli ?
<Bachir> or maybe just write "make" to compile it
<Bachir> and then :
<Bachir> artiq_flash -V femto2
<rjo> see the manual for compiling and flashing
<Bachir> ok thank you
<Bachir> Bye
