|
* The FreeRTOS kernel's RISC-V port is split between the the code that is
|
|
* common across all currently supported RISC-V chips (implementations of the
|
|
* RISC-V ISA), and code which tailors the port to a specific RISC-V chip:
|
|
*
|
|
* + FreeRTOS\Source\portable\GCC\RISC-V-RV32\portASM.S contains the code that
|
|
* is common to all currently supported RISC-V chips. There is only one
|
|
* portASM.S file because the same file is built for all RISC-V target chips.
|
|
*
|
|
* + Header files called freertos_risc_v_chip_specific_extensions.h contain the
|
|
* code that tailors the FreeRTOS kernel's RISC-V port to a specific RISC-V
|
|
* chip. There are multiple freertos_risc_v_chip_specific_extensions.h files
|
|
* as there are multiple RISC-V chip implementations.
|
|
*
|
|
* !!!NOTE!!!
|
|
* CARE MUST BE TAKEN TO INCLUDE THE CORRECT
|
|
* freertos_risc_v_chip_specific_extensions.h HEADER FILE FOR THE CHIP IN USE.
|
|
* If the chip in use includes a core local interrupter (CLINT) and does not
|
|
* include any chip specific register extensions then set the GNU assembler's
|
|
* include path such that the header file contained in the
|
|
* FreeRTOS\Source\portable\GCC\RISC-V-RV32 directory is the header file that is
|
|
* actually inlcuded. Otherwise set the assembler's include patch to the
|
|
* sub-directory off of the
|
|
* FreeRTOS\Source\portable\GCC\RISC-V-RV32\chip_specific_extensions directory
|
|
* that contains the freertos_risc_v_chip_specific_extensions.h specific to the
|
|
* target chip.
