The eMMC and RESET_N pins are diagramed above. Others are listed below.

=== Hardware ===
The cwlite must be modified to support the +1.8V level required by the Vita target. First remove the solder bridge on SJ6, which forces the FPGA logic to 3.3V. Next solder some pin header to JP5 and place a jumper between pin 2 and 3 (the two pins farthest from the FPGA). This will allow the psvemmc target's 1.8V VTarget pin to be used.
=== Software ===
You must use the custom build of [https://github.com/yifanlu/chipwhisperer chipwhisperer]. This build has the target IO restraints set to 1.8V as well as support for the MMC logger/trigger and UART trigger. Follow the installation instructions from [newae https://wiki.newae.com/Installing_ChipWhisperer] and you can execute the glitch scripts by copying them to "software/vita-glitching".
