Summary
Reduced the target voltage and clock frequency in two firmware images to lower electrical and thermal stress and provide a more conservative operating mode.
ADC checks were switched to input mode without pull-ups to avoid actively driving lines during measurements.
During glitch subsystem initialization, eMMC lines are configured as inputs without pull-ups to minimize active influence on sensitive 1.8V signals.
Incorrect status check in mmc_initialize() due to operator precedence
Testing
These changes are based on code review and documentation analysis only. Validation on a physical RP2040 board and the target device is required to confirm correct behavior and to rule out unintended side effects.
