new version of the RTOS kernel pC/OS

Task initialization of the pC/OS Kernel restructured and some minor corrections added.

The idea of expanding the queue to be able to transfer even small data blocks, such as C-structs, was dropped again, as this would have corresponded to the pipe implementation - except for the length storage - including the ~Pend / ~FrontPost weakness during the Copy the data.

new port of the RTOS kernel pC/OS

Cortex-M33

The pC/OS Kernel was ported to the Cortex-M33 with Trustzone-TEE MCUs ST STM32L552 and NXP LPC55S69. As toolchain the ARM/Keil MDK was used.

new port & new version of the RTOS kernel pC/OS

RISC-V

The pC/OS Kernel was ported to the RISC-V of GigaDevices GD32VF103C. As toolchain the NucleiStudio was used.
During this porting a weakness was discovered and eliminated in the memory-manager for kernel requests.

Also the MMC/SD-port (SPI) as well as the pC/SFS (small) Serial File System for SPI- and I2C-interfaces have been ported to the RISC-V of GigaDevices GD32VF103C.

new version of the RTOS kernel pC/OS

SmartMessageQueue as an alternative to MessageBox was added to the pC/OS Kernel. The SmartMessageQueue transfers messages as pure pointers. If the pointer points to an allocated memory block, the ownership of this block is also transferred. If the pointer does not point to an allocated memory block, the risk remains with the user as a non-specific pointer is passed directly.
