For opening it up you unfortunately need some Y-style screwdrivers - let’s see what’s underneath!pic.twitter.com/Gdxt75pwpV
Interesting, an STM32H7B0VBT6 is the main processor! Cortex-M7, 128 KBytes Flash, 1024 KBytes of RAM. Also some unpopulated headers close by that expose SWD (the Arm Cortex-M debug interface)!pic.twitter.com/f5cdSlmin6
Next to it is a Macronix 25U8035 8Mb flash - definitely a candidate to be dumped!pic.twitter.com/23gegjHMjn
Found the SWD pinout! Will check later whether it's enabled or locked!pic.twitter.com/Y0JgwJObZn
Let’s see whether SWD is enabled!pic.twitter.com/c1hxRqRwz5
SWD is enabled, but the device is secure unfortunately, so we can't simply dump the firmware via SWD!pic.twitter.com/dr4KWLJZRH
there are glitches in stm32 that can bypass that fwiw
