Overview ¶
Package spimock provides a fake SPI flash part for unit testing. This simulates an MX66L51235F.
Index ¶
Constants ¶
View Source
const FakeSize = 64 * 1024 * 1024
FakeSize is the size of the mocked flash chip.
View Source
const WriteWaitStates = 5
WriteWaitStates is the number WritePending is set to after a write.
Variables ¶
View Source
var FakeSFDP = []byte{}/* 112 elements not displayed */
FakeSFDP is the SFDP from the MX66L51235F datasheet.

Types ¶
type MockSPI ¶
type MockSPI struct {
// Data contains fake contents of the flash chip.
Data []byte
// SFDPData contains fake SFDP.
SFDP []byte
SpeedHz uint32
// Is4BA is set to true if the chip is currently in 4-byte addressing
// mode.
Is4BA bool
// IsWriteEnabled is set to true if data can be written.
IsWriteEnabled bool
// WritePending is non-zero while a write is pending. It decreases on
// every read of the status register.
WritePending int
// Transfers is a recording of the transfers.
Transfers []spidev.Transfer
// ForceTransferError is returned by Transfer when set.
ForceTransferErr error
// ForceSetSpeedHzError is returned by SetSpeedHz when set.
ForceSetSpeedHzErr error
// contains filtered or unexported fields
}
MockSPI is an implementation of flash.SPI which records the transfers.
func NewFromFile ¶
NewFromFile returns a new MockSPI which is backed by a file. If the file does not exist, it will be created. Ideally, the file's size should match FlashSize.
func (*MockSPI) SetSpeedHz ¶
SetSpeedHz sets the SPI speed. The value set is recorded in the mock.
