This is pre-converted ch585 riscv usb/nfc/ble evt firmware library with gcc and makefile support from WCH official CH585EVT.ZIP.
It is converted by ch5xx_riscv_ble_evt_makefile_gcc_project_template
This firmware library support below parts from WCH:
- ch584
- ch585
The default part is set to 'ch585', you can change it with ./setpart.sh <part>. the corresponding 'Link.ld' will update automatically from the template.
The default 'User' codes is not BLE related, just blink a LED. all evt examples shipped in original EVT package provided in 'Examples' dir.
To build the project, type make.
Ch584/ch585 firmware library use a private extended instruction 'mcpy' in RVMSIS/core_riscv.h as:
__attribute__((always_inline)) RV_STATIC_INLINE void __MCPY(void *dst, void *start, void *end)
{ __asm volatile("mcpy %2, %0, %1" : \
"+r"(start), "+r"(dst) : "r"(end) : "memory");
}
To build ch584/ch585 project, you have to use MRS toolchain instead of building gcc from riscv-gnu-toolchain or prebuilt xpack toolchain, etc.
