01:23 | quitte | Hi. Is there a 1:1 document of the SOM? I need the jtag pads positions for pogo pins. |
02:22 | jnettlet | quitte, you couldn't find what you were looking for on documents on the website? |
02:27 | quitte | jnettlet: I only found a picture of that board region in the user and reference manual. but since I have to drill to .1 mm that is not good enough. I'd prefer to just print a 1:1 picture and put it in the drill press. But I could also use a x-y table if I had the dimensions |
02:28 | jnettlet | quitte, the cad drawing for the microsoms aren't good enough? |
02:29 | quitte | jnettlet: that sounds great - but I did not see them. Or maybe I did and they don't have the jtag test pads? |
02:31 | quitte | jnettlet: do you mean the mechanical description with the board to board connector positions? |
02:32 | jnettlet | quitte, why do you need to drill down? |
02:33 | jnettlet | the jtag interface is exposed as test pins on the microsom |
02:33 | quitte | jnettlet: yes. and i need something to put the pogo pins in |
02:34 | jnettlet | why not just solder on the header you need? |
02:36 | quitte | i did that. it's not reliable enough. the pads are just too tiny to solder something on in a way where I can still move the board |
02:38 | jnettlet | is there a specific problem you are looking into, or is this just for testing? |
02:39 | quitte | i bought the board specifically as some multi-core arm that i can attach with jtag to |
02:41 | jnettlet | okay. I would look at the step file for the 3d model and see if that gives you the dimensions you need. Other than that we always just solder to som points to use jtag, but since we have done the bringup there has been no need. |
02:43 | quitte | jnettlet: could you tell me the x-y coordinates in relation to the center of the two heatsink holes per chance? |
02:44 | jnettlet | quitte, I don't have the information, and since you are modding your som I will leave that up to you. In general I mostly work with software. |
02:45 | quitte | okay. I'll figure out how to open the step file. I'm not modifying the som, however. Just the heatsink. |
