I have a 256-BGA chip (NXP PowerPC) , which I’d like to glitch, however it’s stuck on a PCB now and it’s really hard tracing signals out. So I was thinking it may be a good thing to try to design a CW-UFO victim board. A few questions that popped up:
- Do you have your Altium schematic library published? It will be a great help, as I don’t want to create a lot of footprints from scratch
- Have you had any success with voltage glitching any PowerPC targets, such as SPC5748GSK1MMJ6? If so, is there a log of the procedure anywhere?
- The chip I am targeting has a low-power domain which needs to be supplied by the internal chip regulator using an off-chip NPN driver. This is a requirement and supplying the chip with an external regulator is not allowed. This is not the case with SPC5748GSK1MMJ6, which is the target used in the CW board. I noticed that the glitch is inserted in pin K2 and any of the VDD_LV pins. For my application, I think I could glitch VRC_CTRL and any of the VDD_LV pins. Can you please comment on that?
- I will also need to monitor the VDD_LV line with a scope (need to do power analysis as well), so I am thinking of adding a series resistor and an SMA connector to the line. That will need to be mounted on the target board itself
