This commit introduces the `ChangeSpiFreq` trait to allow dynamic modification of SPI frequencies. Implementations for `StmSpi` and `RpSpi` are added, and the `Serprog` struct is updated to use this trait instead of a callback. This simplifies the code and ensures consistent handling of frequency changes across different SPI implementations. Signed-off-by: Arthur Heymans <[email protected]>
This commit modifies the `Serprog` struct to make the SPI field optional, allowing the program to run without SPI functionality. A new `NoSpi` module is added to provide a no-op SPI implementation for cases where SPI is not available. The `OSpiOp` and `SSpiFreq` commands now check for SPI availability and return appropriate responses if SPI is not present. Signed-off-by: Arthur Heymans <[email protected]>
This commit introduces new enums, structs, and bitfields to support Multi-IO SPI modes and operations. It includes the `MultiIOMode` enum, `MultiIOSpiHeader` and `QMultiIOSpiModesResponse` structs, and extends the `SerprogCommand` enum with `QMultiIOSpiModes` and `MultiIOSpiOp` commands. Additionally, it adds the `IOModeAndDirection` bitfield to handle IO mode and direction flags. Signed-off-by: Arthur Heymans <[email protected]>

This commit introduces a new project called Flashcrab, which includes support for OSPI (OctoSPI) flash memory operations and USB communication. The project also includes integration tests for various hardware functionalities such as DAC, hardware hashing, and LED sequence control. The build system is configured with Flip Link for the Thumbv8m target, and the project is set up for embedded testing. Signed-off-by: Arthur Heymans <[email protected]>
- Introduces new CsControl trait for chip select management - Provides NoCs implementation for no-op CS control = Implements CsControl for OutputPin with single CS support - Updates Serprog struct to use CsControl trait - Adds SSpiCs command handling for CS selection
This commit introduces Multi-IO SPI functionality to the serprog module, enabling support for advanced SPI modes like Dual I/O, Quad I/O, and QPI. It includes a new `multi_io_spi` module, updates to the `Serprog` struct to handle Multi-IO SPI transactions, and new commands (`QMultiIOSpiModes`, `MultiIOSpiOp`) for protocol interaction. The changes also ensure compatibility with existing SPI operations while extending the maximum buffer size handling for Multi-IO transactions. Signed-off-by: Arthur Heymans <[email protected]>
This commit introduces the `OspiWrapper` struct to work around orphan rules and implements the `MultiIOSpi` trait for it. The struct provides methods to build transfer configurations and handle reset, read, and write operations for OSPI (Octo-SPI) transactions. The `serprog` integration is updated to use `OspiWrapper` instead of a dummy SPI implementation. Additionally, the `vbus_detection` configuration for USB is disabled by default for broader compatibility. The changes enable support for multi-IO modes and enhance the functionality of the serprog interface. Signed-off-by: Arthur Heymans <[email protected]>
