Hi , is there an advised JTAG connector for the board that I can buy and solder it?
Just interested in low-level debugging of u-boot, with Segger or whatever debugger.

Hello,
I see on the board there is a JTAG in the form of Tag-Connect | Tag-Connect types.
I made a mistake and got the one w/ the āfeelersā but needed the holder instead.
Seth
P.S. I just researched their pages online, i.e. the tag-connect pages. So, the things I was calling āfeelersā are called ālegsā and not āfeelers.ā There is a holder but it is called a retaining clip.

Great, I will order it, thanks!
Michael.
being you appeared to have gone down this road,
i got a jtag Sipeed SLogic Combo 8 Slogic Analyzer on order
looks like this is the PCB adaptor that is needed, correct me if iām wrong.
TC2050-IDC-NL-050-ALL
down side is that Sipeed is 12 pins and TC2050 is 10 pins
any insight on this ??

@amf99 ,
Helloā¦I have not been able to get it up and running just yet. I started w/ the BBAI-64 and the same type of connector for debugging.
The reason beingā¦
- I do not know what source to use for debuggingā¦
- Do I use Eclipse or another type?
- Can I use VS Code?
Anyway, I have the wrong header but I decided to ābreakā it to make it fit. So, the plug-of-nails works for a connection but I am still wondering about it.
@amf99 , I think reading the Connection datasheet will help. I got the 2050-IDC w/ easy clips (oops). I should have purchased the one w/out easy clips. So, I broke off the easy clips.
No insight so far on the 12 pins versus the 10 pinsā¦
I purchased the XDS110 and not the XDS100v2 by mistake. I am full of follies these daysā¦
Those couple of links are for the BBAI-64 and NOT the Sipeed debugger which can be used for the BeagleV-Aheadā¦ (I am pretty sure).
Switching up exact pins may be neededā¦
This one is what you are describing, I think: TC2050-IDC-NL-050-ALL Plug-of-Nails to 0.05" IDC | Tag-Connect
I will save up a bit and purchase one and get the Sipeed Debugger connector too. I will keep you updated if you bring it up againā¦
thanks for the quick reply, guess we are no longer on the 3 to 4 hour waiting list to do replies, lol
have you looked at this link, seems like they have some software that works, at least to test the connection.
i have one of the XDS100V ? version, donāt recall which, will have to dig this out of the junk box,
as for the VS code, havenāt used that yet, normally use eclipse, which can be a pain to get working each time a new version comes out.
i see rcn posted a link to buy from digi, TC2050-IDC-NL, may have to order one, the sipeed isnāt due in till end of Dec.

I purchased the FlashPro5 and tried to contact the Tag-Connect people.
For some reason, my email failed. Off to try againā¦
Seth
P.S. I will update shortly or on Tue.
@amf99 ,
Alsoā¦there is a couple adapters people have on their tag-connect site.
1. BBAI-64
From what I found so far, the TDA4VM uses the TI XDS110 (Probably Wrong). I just researched the XDS110 and it looks like the TDA4VM was dropped or it never had support. Blah.
Okayā¦so this is the one needed for the TDA4VM: TMDSEMU560V2STM-U Debug probe | TI.com and I will keep looking for other debug probes available for the TDA4VM. Sheesh.
2. BeagleV-Ahead
The onboard chip TH1520 on the BeagleV-Ahead has the plug-of-nails for debugging but I am unaware currently of the connection to the Sipeed debugger and what pins do what now.
3. BeagleV-Fire
And yes, that link you posted has the FlashPro5 as the debugger w/ the plug-of-nails as the board connection.
All 1 - 3 have the plug-of-nails connection from the board to outer resources (pins) that may need different functionality (UART, SPI, GPIO) and currently, I know little so far.
Seth
P.S. I researched the XDS110 b/c of the TDA4VM onboard the BBAI-64. Since then, the two newer boards use different, non-TI chips which may bring different types of debuggers like the MicroChip FlashPro5 for debugging purposes. I will get the link for the TDA4VM and XDS110 useā¦
