Hello,

It sounds like you’re encountering some challenges with entering recovery mode on your custom board using the Verdin AM62 module. Let’s explore some potential areas to investigate that might help resolve this issue:

  1. Hardware Connections: Double-check the wiring and connections of the CTRL-RECOVERY_MICO# pin on your custom board. Ensure that the pin is correctly connected to ground and that there are no unintended resistances or shorts that could affect the signal.

  2. Electrical Differences: Compare your custom board’s schematic with the development board to identify any missing components or differences in the circuitry that might impact the recovery mode. Pay particular attention to pull-up/pull-down resistors and any capacitive loads that might affect signal timing.

  3. Signal Integrity and Timing: Ensure that the CTRL-RECOVERY_MICO# pin is held low for the correct duration. Consider using an oscilloscope to verify the signal timing and integrity during the power cycle. Debouncing issues or incorrect timing could prevent the module from entering recovery mode.

  4. USB Boot Configuration: Verify that your custom board is correctly configured for USB boot. This includes ensuring that the USB connections are properly routed and that the board can communicate with the host PC during the recovery process.

  5. Power Supply Stability: Ensure that the power supply to the module is stable and meets the required specifications during the recovery process. Fluctuations in power can affect the module’s ability to enter recovery mode.

  6. Module-Specific Considerations: Review any module-specific errata or known issues that might affect recovery mode on the Verdin AM62. Ensure that your board design adheres to the recommended guidelines provided by Toradex.

By systematically checking these areas, you should be able to identify any discrepancies that might be preventing the module from entering recovery mode on your custom board. I hope these suggestions help you resolve the issue.
