| sf-slack | <mkurc> I do. I'll check the bitstream | 07:03 |
| *** epony has joined #symbiflow | 07:18 | |
| sf-slack | <mkurc> @olof.kindgren Bad news :( The bitstream seems not to be working. The LED remains off all the time. | 07:22 |
| sf-slack | <kgugala> @olof.kindgren you can use fasm2bels to decompile the bitstream | 07:23 |
| sf-slack | <kgugala> and get structural verilog | 07:24 |
| sf-slack | <olof.kindgren> @mkurc Thanks for checking. It was a shot in the dark. I will do some more detailed analysis once I get a cable | 07:24 |
| sf-slack | <kgugala> you can run simulations with it | 07:24 |
| sf-slack | <kgugala> (this is quite useful in debugging) | 07:24 |
| sf-slack | <kgugala> BTW we have a similar tool fo 7 series FPGAs | 07:25 |
| sf-slack | <olof.kindgren> @kgugala That's handy, but I'm trying too many things at once. First step should really be to see I got correct pin for the LED, reset polarity and that the clock is runnkng | 07:25 |
| sf-slack | <olof.kindgren> Once I have that working it could make sense to do post-p&r simulations if things are still not working | 07:27 |
| *** kraiskil has joined #symbiflow | 07:27 | |
| sf-slack | <kgugala> mhm | 07:27 |
| sf-slack | <kgugala> also it probably makes sense to add fasm2bels support to edalize | 07:27 |
| sf-slack | <kgugala> :) | 07:27 |
| sf-slack | <olof.kindgren> @kgugala Yes. netlist/gatelevel simulations is one of the reasons I'm looking at building a next-generation Edalize (called Edalize Slight Return for now) | 07:30 |
| sf-slack | <olof.kindgren> https://github.com/olofk/edalize/wiki/Edalize-(Slight-return) | 07:30 |
| sf-slack | <kgugala> Return of the sims | 07:31 |
| sf-slack | <kgugala> ;) | 07:31 |
| sf-slack | <olof.kindgren> Does anyone know a particular brand of these SWD cables that are both supported by OpenOCD and has the right connector? | 07:31 |
| sf-slack | <mkurc> @olof.kindgren Regarding the PB-SDIOMUX error: You are using the binary toolchain provided by QuickLogic right? Can you tell which version? (release). I recall an issue with those SDIOMUX pins and I'd like to double-check if it is not a lingering bug there. | 07:36 |
| sf-slack | <olof.kindgren> Should be 1.2 Will double check | 07:37 |
| sf-slack | <olof.kindgren> Yes. Installed from `Symbiflow_v1.2.0.gz.run` | 07:37 |
| sf-slack | <mkurc> Ok, thx. | 07:38 |
| sf-slack | <olof.kindgren> Related to that, can you verify which pin number I should use in the pcf for the red LED on the quickfeather board? | 07:38 |
| sf-slack | <kgugala> @olof.kindgren regarding the cables - I think we should soon open source Antmicro's adapter - the latest revision supports SWD and can be used with QF (I also tested the current revision with some other boards e.g. OrangeCrab and it works fine) | 07:40 |
| sf-slack | <olof.kindgren> That would be cool. Wouldn't help me in this particular case though since I guess I would still need to build one :) | 07:41 |
| sf-slack | <mkurc> So Quickfeather uses the chip in PU64 package. You may refer to IO pins either by number or by "alias" (eg. IO_20). The RGB led uses IO_22, IO_21 and IO_18. | 07:45 |
| sf-slack | <olof.kindgren> @mkurc Cool. So yesterday I tried `22` which didn't work and then `34`. Do you mean that `IO_22` is an alias for `34`? | 07:49 |
| sf-slack | <mkurc> Yes it is | 07:49 |
| sf-slack | <olof.kindgren> Hey, I just found a video which describes how to use a TinyFPGA (hopefully BX) to program the board. Might try that later | 07:49 |
| sf-slack | <olof.kindgren> @mkurc Cool. Thanks. Then I got the pinout correct at least | 07:49 |
| sf-slack | <mkurc> great :) | 07:50 |

| mithro | kgugala: You should be able to use to the USB bootloader to program the QuickLogic device, right? | 20:25 |
| sf-slack | <kgugala> @mithro yes, you should. The device should come preprogramed with the USB - UART bitstream. This should allow you loading bitstream using firmware running on the CPU | 20:28 |
| sf-slack | <kgugala> I never used this | 20:28 |
