• I was told by experts:
  • Legacy ARM 7, 9, 11 architecture - Deterministic I/O time was practically impossible. For I/O ( or interrupt routines ?! ), the C compilers generate 5 non-atomic commands, plus 2 other commands. It was necessary to disable interrupts for deterministic I/O operations - This is not acceptable for many applications and systems.
  • ARM Cortex architecture - Now there are just 3 atomic commands necessary for I/O ( or interrupt routines ?! ), but the sequence can be still interrupted of course. So either it is not necessary to disable interrupts for I/O operations, or at least the time with disabled interrupts is much shorter.

1. AFAIK, there is a unique MAC address (1) - as the Raspberry uses a dedicated commercial Ethernet chip onboard, which supplies this MAC address ?!
   • Raspberry Pi Spy "Finding the MAC Address of a Raspberry Pi".
   • If so, You may use the Raspberry board freely, in the Internet.
2. AFAIK Raspberry passed CE certification (2).
   • Raspberry Pi "Tag: CE compliance".
   • Your device in which your board operates, needs a CE certification too (3).
   • If so, and if your device fulfuls the conditions (1)+(2)+(3), You might put it on the market.

• In opposite, evaluation boards and demonstration boards of chip manufacturers nowadays often include the Ethernet function in the CPU chip. They provide non-unique MAC addresses and USB client device numbers “for evaluation and development purposes only”.
  • You may not use use such boards freely in the Internet, with these non-unique MAC addresses.
  • To put it on the market, you must get a legal unique MAC address and / or a legal unique USB client address. Additionally the embedded device in which your board is operating, must be CE compliant.

That's why you must not connect the JTAG interface of the device to a remote PC, while the device is plugged into a 230 Volts power socket, under any circumstances. For practical work in a laboratory - and just there ! -, you need to use a insulating transformer to isolate the 230 Volts power supply from the device.

• In opposite to earlier design approches for bare-metal microcontroller, a huge amount of RAM is supplied to enable a change in the usual development workflow of embedded software:

  • You are asked to develop your complete software in RAM. As final step of software development, you should then convert the application to a Flash application.
  • In opposite to the standard CCS toolchain, you need an externally provided tool for flash programming.

  • The Xilinx ARM SoC chip has 256k of internal RAM. This might be enough to run Linux as application on the first ARM core on external RAM memory, and a small realtime operating system ( e.g. FreeRTOS ) as application on the other core, with internal 256K RAM memory. The code of the small realtime operating system and its individual application might run in RAM, with full CPU speed. Running this from slow Flash memory does not provide the wanted computing power.
  • In opposite, Altera's ARM SoC chip has just 64K of internal RAM. This is not suitable to run even a small realtime operating system and its individual application, in RAM, usually.

• mbed - “The fastest way to prototype with ARM based microcontrollers”.

• Events vs. interrupts:
  • Events cause the MCU core to wake up, but no code is executed.
  • Interrupts cause the MCU core to wake up and to execute instructions ( jump to and execution of interrupt service routines ).
• I was told by experts: With early releases of ( just StMicroelectronics ? ) Corex M0+ MPUs, there were problems with in events by the ARM core, but now with current production releases, this is past and now everything works fine.

• According to experts,
  • it is more energy efficient to wake up a MPU every second, which runs with high frequency,
  • then to run a MPU with low clock all the time.
• , because chips in CMOS technology consume power, as soon as the MPU is active.

• According to experts, FIFO is an outdated concept of the 1980th and 1990th.
• With current MCUs, incoming data is stored in a 16-32 bit shift register, and is then transfered by DMA to the target memory locations.

• The MCU “ARM Cortex M0” has no unprivileged level.
• You may write an ARM Cortex application in C language “from the first line on”. There is no need as with other MCUs first to have some assembly code.
• Assembly code, code copy direction.
  • Mathematical operations - Intel style:
    • “ADD R0 R1” → R0=R0+R1.
  • Load+store operations - No unique code copy direction.
    • “LD R0, [R1]” → [R1] = R0.
    • “STR R0, [R1]” → R0 = [R1].
  • The number of IRQ priorities ( 8 - 256 ) of ARM Cortex M3, M4, M7 depends on OEM decisions.
