| mithro | somlo / tnt / geertu: Know anyone who might be able to help CarlFK? | 01:31 |
|---|---|---|
| somlo | I don't have an arty, but on any board I've used one can simply program the bitstream into the board via openocd, and that counts as a (very "low level") reset, no physical btton push needed | 01:39 |
| somlo | beyond that, I got nothing :) | 01:39 |
| somlo | unless you mean you want the LEDs to respond to some sort of user action, not just start blinking upon reset or bitstream being programmed | 01:42 |
| mithro | somlo: Well, CarlFK is trying to enable people to have remote access to Arty boards | 01:42 |
| CarlFK | somlo: I'll add your public key to the host and you can give it a shot? what's your github name? | 01:43 |
| somlo | in which case, I don't know -- have some fancier demo program that's ethernet enabled, up to and including running linux, and control it that way | 01:44 |
| CarlFK | simple - I just want to confirm something works other than the power led | 01:44 |
| CarlFK | fancy is the wrong direction | 01:45 |
| CarlFK | although if you want to do all those things you said, that's fine too - we will find out if something works | 01:46 |
| somlo | CarlFK -- I might still be misunderstanding here, but when the board is reset, the LEDs look a certain way; then, if you push a litex bitstream, they start blinking in a litex-specific way -- so you can tell the difference | 01:47 |
| somlo | all that can be done w/o physically touching the board | 01:48 |
| somlo | now, getting it physically reset so that it does the "factory default led thing" again might be tricky | 01:48 |
| somlo | if you have a way to power-cycle it remotely, that would be one way to take care of that portion :) | 01:50 |
| somlo | e.g., some sort of "managed" USB hub where you can turn off power to a port through some software API | 01:51 |
| CarlFK | I do - PoE to the pi, Arty is hooked to Pi, so it all goes down | 01:51 |
| somlo | so once the board is in factory default mode, openocd to send a bitstream to it will get it to do the litex led demo thing again | 01:52 |
| somlo | rinse and repeat | 01:52 |
| somlo | you can probably use an even simpler and smaller led blinky bitstream than LiteX, if you want to optimize for bitstream size :) | 01:53 |

| _franck_ | CarlFK: which Arty do you have ? I can give you a blinker (or something else) for a Arty-A7 35T | 08:45 |

| _florent_ | tnt: if the Xilinx Platform Cable is FTDI based, it should work for JTAG Bone. I'm personnally mostly using JTAG HS2 cables | 17:29 |
| tnt | _florent_: I don't think it is. It has a cpld inside IIRC. | 17:31 |
| tnt | and a FX2 (it needs a firmware loaded) | 17:31 |
