CP2102 details about orbuculum

[mubes]

Hi sorki, good to have you aboard. The more people who start using this then the more solid we can make it all. Your command line isn't quite right, try;

orbuculum -b swo/ -v 3 -a 115200 -p /dev/ttyUSB0

(Oh, and please make sure you're using the latest version of the code, I tidied the command line options a couple of weeks ago, so if you happen to have an older version you might be out of date).

...and see if that helps you move forward. You've also switched in the TPIU with your prepareSWD statement, so you might want to try this in the first instance (since you don't have the -t option on the orbuculum command line);

prepareSWD 72000000 115200 0 0

Given that you're outputting sample Program Counter data with the .gdbinit you attached you will definitely hit overflow issues. Once you've got this running I'd love you to try the HX8 board but only 1 or 2 bit TRACE width is working at the moment....I'm currently working on the 4 bit support. That stuff remains very experimental for now, but there are very good things coming on that side.

Regards

Wow, it works with the command line you provided - kind of at least as I'm getting only

80 IDLE --> TS(1) : 79 TS --> IDLE(1)

and no samples in orbtop. I'm mostly interested in orbtop as it feels like the last missing piece in my tool-chain for quickly discovering timing / performance issues.

I'm running the latest version, seems easily package-able for Nixos. sorki/nixpkgs@7bbe749

For 1 or 2 bit tracing with HX8 do I need to change anything in toplevel verilog file?

OK, You're collecting timestamps, so that's promising. Here's my dwt configuration that's creating orbtop output for me right now;

dwtSamplePC 1
dwtSyncTAP 3
dwtPostTAP 1
dwtPostInit 1
dwtPostReset 15
dwtCycEna 1

For two bit output from the HX8 set .width(2) in toplevel.v and make sure you've got prepareTRACE 2 in your gdbinit.

Sorki,

I've heard nothing back on this for two weeks now, so I am assuming your issues are resolved and closing the issue. Please feel free to follow up if you need more.
