Enumeration Type Documentation

pico_error_codes

enum pico_error_codes

Common return codes from pico_sdk methods that return a status.

All PICO_ERROR_ values are negative so they can be returned from functions that also want to return a zero or positive value on success.

Note these error codes may be returned via bootrom functions too.

Enumerator
PICO_OK	No error; the operation succeeded.
PICO_ERROR_NONE	No error; the operation succeeded.
PICO_ERROR_GENERIC	An unspecified error occurred.
PICO_ERROR_TIMEOUT	The function failed due to timeout.
PICO_ERROR_NO_DATA	Attempt for example to read from an empty buffer/FIFO.
PICO_ERROR_NOT_PERMITTED	Permission violation e.g. write to read-only flash partition, or security violation.
PICO_ERROR_INVALID_ARG	Argument is outside of range of supported values`.
PICO_ERROR_IO	An I/O error occurred.
PICO_ERROR_BADAUTH	The authorization failed due to bad credentials.
PICO_ERROR_CONNECT_FAILED	The connection failed.
PICO_ERROR_INSUFFICIENT_RESOURCES	Dynamic allocation of resources failed.
PICO_ERROR_INVALID_ADDRESS	Address argument was out-of-bounds or was determined to be an address that the caller may not access.
PICO_ERROR_BAD_ALIGNMENT	Address was mis-aligned (usually not on word boundary)
PICO_ERROR_INVALID_STATE	Something happened or failed to happen in the past, and consequently we (currently) can't service the request.
PICO_ERROR_BUFFER_TOO_SMALL	A user-allocated buffer was too small to hold the result or working state of this function.
PICO_ERROR_PRECONDITION_NOT_MET	The call failed because another function must be called first.
PICO_ERROR_MODIFIED_DATA	Cached data was determined to be inconsistent with the actual version of the data.
PICO_ERROR_INVALID_DATA	A data structure failed to validate.
PICO_ERROR_NOT_FOUND	Attempted to access something that does not exist; or, a search failed.
PICO_ERROR_UNSUPPORTED_MODIFICATION	Write is impossible based on previous writes; e.g. attempted to clear an OTP bit.
PICO_ERROR_LOCK_REQUIRED	A required lock is not owned.
PICO_ERROR_VERSION_MISMATCH	A version mismatch occurred (e.g. trying to run PIO version 1 code on RP2040)
PICO_ERROR_RESOURCE_IN_USE	The call could not proceed because requires resourcesw were unavailable.
