The pC/OS Kernel was ported to the Cortex-R4 from TI - TMS570. As toolchain the ARM/Keil MDK and the IAR Embedded Workbench with minimal MCU initializing was used.

The pC/OS Kernel was ported to the Nuvoton Cortex-M23 M2351 with support of the TEE. As toolchain the ARM/Keil MDK was used. As in the demo shown, it must be guaranteed that only one task can ever go into the TEE (blocking-semaphore or mutual-exclusion for serialization).

Also the pC/SFS (small) Serial File System has been ported to the Nuvoton M2351 for SPI- and I2C-interfaces.

The porting of the pC/OS Kernel to the Synopsys ARC-EM has been redesigned to support the TEE (secure shield). As in the demo shown, it must be guaranteed that only one task can ever go into the TEE (blocking-semaphore or mutual-exclusion for serialization).

The pC/SFS (small) Serial File System already runs on the ARC-EMSK board and can now work in TEE (secure shield) or in none-secure mode.

The pC/OS Kernel was ported to the Microchip/Atmel SAMD51. As toolchain the ARM/Keil MDK and the IAR Embedded Workbench was used.

Also the pC/SFS (small) Serial File System has been ported to the Microchip/Atmel SAMD51 for SPI- and I2C-interfaces.
Possibly the file system may use the QSPI interface soon ...;-)

The porting of the pC/OS Kernel to the Microchip/Atmel Cortex-M23 SAML11 has been redesigned to support the TEE. As in the demo shown, it must be guaranteed that only one task can ever go into the TEE (blocking-semaphore or mutual-exclusion for serialization).
In addition, the porting of the pC/OS kernel to the Cortex-M33 (ARM MPS2-FPGA) has also been extended identically.

The pC/SFS (small) Serial File System already runs on the SAML11 and can now work in TEE (secure shield) or in none-secure mode.

The pC/OS Kernel was ported to the Microchip/Atmel SAML10 and SAML11. As toolchain the ARM/Keil MDK was used. The used boards were adapted Rabid Prototype TAU boards.
But I noticed something:

• the SAML10 (without TEE) uses the classical EXC-RETURN scheme
• the TEE of the SAML11 is still not actively supported by the pC/OS kernel
• The SAML11 does not have a Secure Access Unit (SAU) but instead he is partitioned via the Implementation Defined Attribution Unit (IDAU) and Peripheral Access Controller (PAC). This results in settings in the NVM User Row (UROW) and possibly also in the NVM Boot Configuration Row (BOCOR). But I have to understand that first of all ...

It's Microchip that has the first ARMv8-M to buy.

• SAML10 - Cortex-M23 without Trustzone (TEE) and without crypto accelerators
• SAML11 - Cortex-M23 with Trustzone (TEE) and with crypto accelerators

The pC/OS Kernel was ported to the Renesas RL78. As toolchain the IAR Embedded-Workbench was used.

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.

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.

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

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

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.

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

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.
