revised porting of the RTOS Kernel pC/OS

RISCV

The porting of the pC/OS Kernel to the RISC-V of SiFive FE310 has been revised again. The central trap-entry (system-exceptions & timer/user-interrupts) has been optimized and the software-interrupt is finally working cleanly.

SDUC cards with up to 128TB

SDUC

The next generation of SD cards is comming - SDUC (Ultra Capacity) - with up to 128 TB. Let's see how long the new upper limit lasts...;-)
The new additional interface SD Express (PCIe-3.0 plus NVMe-1.3) enables data rates of up to 985 MB/s.

new port of the RTOS kernel pC/OS

Renesas RX

The pC/OS Kernel was ported to the Renesas RX210 and RX62N. As toolchain the IAR Embedded-Workbench was used.

new port of the RTOS kernel pC/OS

Cortex-M4

The pC/OS Kernel was ported to the Freescale MK60DN and MK66FX. As toolchain the ARM-Keil MDK was used.

new port of the RTOS kernel pC/OS

MIPS PIC32MZ

The pC/OS Kernel was ported to the Microchip PIC32MZ and the ports to the Microchip PIC32MX renewed. As toolchain the MPLAB-X IDE and an J-Link EDU (mini) was used.

new port of the RTOS kernel pC/OS

EFM32HG

The pC/OS Kernel was ported to the Cortex-M0 Silicon Labs EFM32. As toolchain the ARM-Keil MDK was used.

extension of the (small) Serial File System pC/SFS

The pC/SFS (small) Serial File System was getting an optional extension SFS_RemoveDirTree(..). The link-handling was also corrected.
A directory can now be deleted completely with all contained sub-elements (Dir / File / Link). However, a link from outside into this sub-tree can not be resolved and thus remains as an error. All other links (internal or external) may be resolved.

correction in the (small) Serial File System pC/SFS

The pC/SFS (small) Serial File System was getting a correction in internal functions SFSMem_Alloc() & SFSCreate_Entry().
The creation of a directory wasn't working cleanly.

new port of the RTOS kernel pC/OS

Synopsys ARC

The pC/OS Kernel was ported to the Synopsys ARC-EM. The nSIM simulation and the ARC-EMSK FPGA-board were used for this.
This ARC-EM port does also not include active support for the TEE (here SecureShield) like the ARMv8M port, so all functions in the secure-side are to be treated as a collection of a single resource, so only one task can be in the secure-side (SecureShield) using a function call.

Also, the pC/SFS (small) Serial File System has been ported to the Synopsys ARC-EMSK board.

tiny correction in the (small) Serial File System pC/SFS

The pC/SFS (small) Serial File System was getting a small correction in internal function SFSChange_Entry().
The API-function call SFS_ChangeDir("/") wasn't working correctly.
