I removed the cap on the top grey line on the left to get better access to the trace underneath the leg of CPVDD and was able to cut it successfully. I used a pretty sharp hobby knife with a pretty pointy blade tip and was able to get underneath it to cut that trace.
I unfortunately expose a bit of the ground plane I believe that’s on top of the rest of the board surround the IC. I don’t expect it to be an issue but I’ll keep and eye on it, cleaned the area a bit to get any remain copper particles out and flux off.
Getting that cap back on is another issue. I haven’t done yet but I have a very small soldering iron that might be able to do the job. I have little experience getting components that small back on their traces. It’ll be an interesting adventure.
Thanks for the picture that really helped btw. Had no idea that there was a trace underneath and that XSMT needed 1.8v as well. I should be able to tap the positive side of the rail caps hooked up to DVDD, LDOO with wire wrap and then jumper them together to a 1.8v source
Thank you again. I’ll let you know how it goes with i2s on the HiKey 960. That’s my next adventure with this project
Also, exposing that trace so that cutting is easier would be a nice revision to the board would be nice btw
