MSP430 Fails to Boot Firmware After Random Event (Possibly ESD Shock)

[Sergio5714]

Affected HW/FW Revision: 1.0.0 - 1.2.1 (Acquisition PCB)

Description: The MSP430 microcontroller stops booting firmware after an unpredictable event, possibly due to an ESD shock.

Symptoms:

• The probe successfully establishes communication with the dongle.
• However, when starting the acquisition, the process hangs.

Recovery Steps:

• After connecting the probe to the debugger, flashing is initially not possible (memory erase fails).
• However, after entering Debug mode, flashing becomes possible again.
