While ridiculously fast, it did have its limitations. Access to source code means ease of adaptation and debugging. Chipset modules are licensed for a one-time fee rather than a unit royalty. In an attempt to reduce confusion various suffixes are used, and in some cases utility macros are provided to access the registers:. The package does not contain any configuration options. The platform HAL can override this definition if necessary.

No more ” keyboard failure – press F1 to continue ” errors. A is the closest replacement I could find, easy to get through www. The central processor is largely compatible and can run at up to MHz.
Linux gpio driver for stpc atlas
Features not needed or desired for embedded use have been left out. In an attempt to reduce confusion various suffixes are used, and in some cases utility ilnux are provided to access the registers:.
This macro executes a hlt instruction, suspending the CPU until the next interrupt and thus reducing power consumption. Chipset support for two chipsets is open.
Compact SBC includes analog/digital I/O, runs Linux
Some are based on information that was provided to me by chip manufacturers under non-disclosure agreements. The BIOS core is less than lines of assembly code, very manageable. An eCos configuration for an STPC Atlas-based platform should also include a platform HAL package to support board-level details like the nature of the external memory chips.
When the variant HAL’s clock macros are enabled the package will also provide profiling timer support.
While ridiculously fast, it did have its limitations. The platform HAL can override these definitions if platform-specific macros are more appropriate.
It is intended for use in embedded systems. The implementation uses the processor’s PIT0 timer since that is the only on-chip timer which can generate interrupts.
The package does not contain any configuration options. Your time is worth more than that. The platform HAL determines the default clock frequency, and can override any of these definitions if required.
It is up to the platform HAL to define the interrupt vector numbers. I consider the CPL to be a flexible, well-written license. In an attempt to reduce confusion various suffixes are used, and in some cases utility macros are provided to access the registers: The legacy BIOS specifications require parameter passing in registers rather than on the stack. Chipset atlss are licensed for a one-time fee rather than a atlzs royalty. Chipset modules for other parts can either be implemented by the user or licensed from PC Engines for a one-time fee.
Implementing new chipset modules requires more experience. Implementing this in C would be very cumbersome.
Less code around lines – easier to understand and navigate. It should be read in conjunction with similar sections from the architectural and platform HAL documentation. Anyone may implement and publish their own chipset modules.
The implementation of other parts of the HAL specification is unaffected, and no additional functionality is provided. I will gladly refer customers to them, or add them to the open source code base.
Unloading the package should only happen as a side effect of switching target hardware. STPC Atlas registers can be accessed in a variety of ways. Not recommended for new designs – please consider coreboot as an alternative. It should never be necessary to load this package explicitly. Access to source code means talas of adaptation and debugging.
