Hello everyone, is possible to use ChipWhisperer-Lite, for glitch in this STi7111 board, on uart port or jtag?
I know the pinout of both

Hello,

The ChipWhisperer-Lite supports both Vcc and clock glitch, so in theory it’s able to glitch most targets. Keep in mind that the Lite only has a basic trigger (just rising/falling edge) and a max clock frequency of 300MHz, so if you need a complicated trigger setup or your target is running at a high frequency, the CWLite might not meet your needs.
