resumeProg (SPIFlash)

Signatures

• bool SPIFlash::resumeProg(void)

What It Is For

Resume a previously suspended program/erase operation.

Parameters

• No parameters.

Behavior Details

Pair this with suspendProg to complete long operations after temporary interruption.

Return Semantics

Returns true on successful resume.

Failure Behavior

Fails if no suspend state exists, command unsupported, or chip state invalid.

Common Mistakes

• Calling resume without a valid suspended operation.
• Assuming resume success without verifying final data integrity.
• Ignoring failed resume and continuing normal writes immediately.

Choosing Between Similar APIs

• Use resumeProg() only after confirmed suspend state.
• If suspend is unsupported, keep single-operation flow without resume logic.
• Validate final data after resume on your exact chip.

Example

flash.suspendProg();
// do urgent task
flash.resumeProg();
