SPI NOR Test Pads
Test pads are available on the back of the board to access SCK, MISO and CS between the SoC and the NOR utility flash. MOSI is also present, but is buried in an internal layer (second from back) which can be accessed by carefully scraping off the top FR4 using a sharp tool, or by using a tiny carbide bit on a milling machine.
