new version of the pC/OS

A small correction in pC/OS for OS_Pipe...Post. An interrupt and during sheduling is switched off a sender can't use the fast mode on OS_Pipe...Post since data source can't be guarantied.


When will the first ARMv8-M MCU be available ?


After I was able a few years ago to co-develop the L4-microkernel 'MobiCore' (now 'Kinibi TEE' of trustonic) already on Trustzone of ARMv7-A products from Samsung (Exynos4 and Exynos5) and Qualcomm (Kait), I am now looking forward when the first ARMv8-M MCU comes from a chip maker. The ARMv8-M specifications see once already promising. I'm curious how well and safely the TrustZone is useful by the special call - with or without a secure-OS and without a separate memory.
In addition to the 'small' TrustZone I'm excited about the new stack-limit register, the improved MPU and the new CryptoCell's.

In any case, the ARMv8-M (and ARMv8-R without TrustZone but with Hypervisor, e.g. ARMv8-R52) could inspire strongly the IoT- and automotive-world when a good security concept (secure-boot, keys & management, containering, storage) is used!


DCF radio clock with I2C OLED-display too

Open/Free BSD urndis ≠ Microsoft RNDIS

BSD writes:
The urndis driver provides Ethernet access over Remote NDIS (RNDIS), allowing mobile devices such as phones and tablets to provide network access. It is often referred to as USB tethering, and in most cases must be explicitly enabled on the device.
urndis should work with any USB RNDIS devices, such as those commonly found on Android devices. It does not support different media types or options. For more information on configuring this device, see ifconfig(8).

But after some tests... Open/Free BSD urndis is not equal to Microsoft RNDIS !

ScanDrive now MassStorage & CCID

ASSD card

The ScanDrive, based on the SAM3SxA_Stick, now works as a USB-composite with MassStorage and CCID too. (see MSC & CCIDdevice-manager)
If a secure µSD Karte with support of ASSD is connected, now you can communicate with the embedded secure-element via the simple interface of the ScanDriveViewer (mass storage vendor commands) or regular via CCID-class and PC/SC. The required ATR for CCID of the secure elements is generated by the Blackberry description as "virtual ATR" (MSC & CCIDWindows / MSC & CCIDLinux) from the card registers.

microSDXC card

SanDisk introduces a microSDXC-card with 200GB.
Although this is a crooked value - from the view of the 2n rule - but is currently the highest feasible capacity on a microSDXC-card.
The 400 US-$, so 2 US-$ per 1GB, are also an announcement...

high-speed SPI mode of the SD/SDHC/SDXC-cards supported

high-speed SD mode

The MMC/SD-port now supports for all SD-cards the high-speed mode too (since SD 2.00 specified) with max 50MHz. But this is optional for the card and is not supported by all manufacturers (such as SanDisk 03-4453) offered. If it is possible, now reverted to high-speed.

picoQuadcopter - interim ...

The basic system is setup! Based on the pC/OS Kernel data from the MPU9150 and the Deltang RX31 receiver are collected and by a exchangeable mathematical processing forwarded onto the motors via PWM. Currently, this process is still very primitive and the picoQuadcopter behaves as - a firecracker :-)
But that is exactly what I want, now it goes to the inner core - the understanding of signal processing!
And I've also learned the following points:

  • the MPU9150 takes more than 2 seconds as "boot up time" until you can communicate stable with it via I2C
  • the battery should be sit tight, otherwise there are usually control problems by weight shift
  • a watchdog should be used to stop the motors on system errors

    Here are some photos and a video of the first flight tests: engines / on the scale 1 / on the scale 2 / on the scale 3 / first test flight :-)
    A separate page for documentation of the project career with more details and HW/SW description will be created soon ...

    ScanDriveViewer Android App


    The ScanDriveViewer application for the SAM3SxA_Stick as MMC/SD ScanDrive is now ported to Android too.
    Additional to the usual data on the inserted card in the ScanDrive, this app also decodes and shows the data of the internal (e)MMC memory and - when available - of the in the device itself used (micro)SD card.

    minimum requirements:
    • at least Android 3.1 (with USB-Host support for the ScanDrive)
    • support of USB-devices with 500mA max. power consumption (for ScanDrive + 256GB card)


    mini fix in the RTOS kernels pC/OS

    fix in the MMC/SD-port

    A small fix in the MMC/SD-port McEx/ASSD extension (secure micro SD). The returned APDU-response now includes its own lenght in the first 2 bytes.


    first SDXC card 256GB available

    SDXC cards

    Lexar offers as the first manufacturer 256GB SDXC cards and other manufacturers will surely follow soon. Now we have arrived the middle of the of the current SSD capacity. Remember: a blu-ray disc is 50GB :-)


    McEx/ASSD extension of the MMC/SD-port

    ASSD cards

    Based on the ASSD extension of the MMC/SD-port for SD-cards supporting McEx/ASSD (secure micro SD) now APDU exchange with this cards (the embedded secure element and the on it installed applets) is possible/supported.


    update of the MMC/SD-port

    A first update of the MMC/SD-port for SD cards supporting McEx/ASSD (secure micro SD). Although the ASSD module is not included, but some small preparations (eg high-speed SD card support) are thus already available in advance.


    update of the MMC/SD-port

    An update of the MMC/SD-port for the detection of SD 4.00 cards. Functional, compared to SD 3.00 cards in SPI mode, nothing has been changed, except the concrete recognition of the SD version. The spec now defines exactly when a card, depending on their capacity, is SD/SDHC/SDXC and what version of CSD and security-extension depending on spec version is to use...


    first SDXC cards 128GB available

    SDXC cards

    SanDisk and Lexar offers as the first manufacturer 128GB SDXC cards. Other manufacturers will surely follow soon.
    Who can use it (Mobiles/Tablets/Photo) ?
    Any device which also supports SDHC cards without limiting C_SIZE of the card - nearly all! Only if the device does not support exFAT, the card must be reformatted (FAT32) and thus no files with a size larger than 4GB can be stored.


    first µSDXC-cards announced

    microSDXC cards

    SanDisk and Kingmax announce as the first manufacturer µSDXC cards with 64GB and 128GB are in prospect. Other manufacturers will surely follow soon.
    At what level prices will be located at the start remains to be seen. I've heard something from 220 Euro...

    The project includes again basic functions for the user for character and string output, cursor handling and some graphics functions.


    MMC/SD-port with first SDXC-card tested

    The MMC/SD-port now is tested with the first SDXC-card (Transcend 64GB SDXC) too and runs fine !
    But for exFAT on Windows XP and Server 2003 the Update KB955704 is required. Older versions of Windows are not supported.
    And VERY IMPORTANT: Only very few professional card reader like the IOgear GFR204SD (and almost no internal reader of notebooks) support at present SDXC based upon SD3.00 !


    additional SDXC-cards in shops

    Next manufacturers announce or offer 64GB SDXC-cards. Only the price move is still not really down. So I am still waiting a little...
    Additional the first card reader with SDXC-support finally dive in to online shops.


    new ports of the RTOS kernel pC/OS


    The pC/OS Kernel was ported to the Cortex-M3 LPC13xx and to the Cortex-M0 LPC11xx.


    first SDXC-cards in online shops

    The first 64GB SDXC cards are available on the Internet. But even the prices are 250 to 490 US-$, but the dance is open. Only at these prices I'll probably wait a little...
    But the aim is therefore clear - the microSDXC class 10 card with 2TB ;-)

    A first update of the MMC/SD-port for SDXC cards. Furthermore, the error was finally corrected in the Nbs calculation plus Nac and Nbs fix for SDHC cards on the specified values.


    new version of the RTOS kernel pC/OS

    Using the optional function OS_TaskDestroy() in the new pC/OS Kernel, Tasks, waiting on an IPC (semaphores/MBox/queue/pipe/..) or owner of a mutex, can now be canceled.
    Furthermore, the source code was restructured without deteriorate the optimization of the different compilers.


    SDXC cards with up to 2TB

    The next generation of SD cards is comming - SDXC (eXtended Capacity).
    With up to 2TB, accelerated interface and using exFAT as filesystem it remains now only wait and see whether the SPI-mode is still supported. The specification is still coming in this quarter of 2009.

    delayed update of the pC/OS

    Finally, a long overdue update of the pC/OS Kernel against "neested interrupts" on ARMs and Cortex.


    updates for pC/OS and pC/TFS

    With the update of the pC/OS Kernel now its possible to reduce the needed RAM in the task administration if only a few tasks in defined. In addition a unique task-ID was added, which can be used on other modules like pC/TFS, to reduce the RAM in the administration of known tasks. And so the identification of a task is clearly (see ChangePrio and Mutex).
    The update of the pC/TFS FileSystems includes the new function TFS_SetEOF(..) and the new task identifying of pC/OS.


    first Cortex-M3 port of pC/OS


    The port of the pC/OS Kernel on Cortex-M3 Luminary LM3S811 is now finished.

    redesign of pC/LZFG plus COP

    Further problem details from the bug reporter caused me to redesign the pC/LZFG Decompressor in case of CRC size, endianess and alignment completely. Now the length and CRC of org-file will alltimes stored big endian in the cop-file and the CRC is always 16bit - in the 32bit version of COP too !
    So the pC/LZFG module and the PC-compress/decompress COP were revised. In order to distinguish this from the past, incompatible older versions, a modified LZFG signature in the cop-file is used.
    (and thanks again to the bug-reporter Baruch Cochavy !)


    bugfix in pC/LZFG

    Such a thing should not happen to me after 2005 again!
    A not correctly initialized variable in pC/LZFG Decompressor produced a wrong output. Sorry !

    big modules update

    Update of all pC/... modules to U08..U32 types. Some additional type-adaptations and better portability of some modules for RTOS-less use implemented.


    small update of pC/OS provide

    Due the porting to the first 32-bit processor necessarily became a first small update of the pC/OS Kernel.
    Furthermore I inserted the past conditions of the AT91SAM7Sxx-Port using Keil. This does not run however so far stably. I still get at the most unbelievable Opcodes Undef_Handler-, PAbt_Handler- or DAbt_Handler- aborts.


    AT91SAM7Sxx port of pC/OS ready

    The port of the pC/OS Kernel on AT91SAM7Sxx is now finished.

    Only why Rabbit needed 4 months for it... ? - But thanks HY-LINE !


    new version of pC/MEM Memory-Manager

    MEM_CleanUp and the for this needed task-registration added.


    total confusion

    Since Rabbit Semiconductors doesn't have it seemingly necessary...
    So I must look for a new development-board for the previous communication-ports and still lacking (for example FireWire). But which board is ideal for it and has a little-edian-core, linear addressroom and is min. 16 bit ? (as counter part of the 8051)
    Who can help me and recommend a board ?


    new development kit purchased

    After I have changed my OS on PC, I can't use my old Am188ES development board. So I have purchased a Rabbit RCM3400 Development kit, but I still waiting for shipping since 8 weeks.
    What's the problem ?


    new version of pC/TFS FileSystem

    TFS_GetFreeSize and TFS_MoveFile added. Bugfix in TFS_Repair, TFS_RenameFile and TFS_RenameDir.


    new version of pC/OS Kernel

    MUTEXes added, Eventgroups correct implemented and code-cleanup

    the reference-manuals now can direct printed (IE6.0 and Moz1.4 tested)



    I'm very busy at this time.
    It's not allowed for Me to make all modules available or to download. But some still follows...
    The Konqueror from KDE 3.1 looks well! But unfortunately he now has the same problems like the Opera-Browser approximately. Keep it up - next time... :-))


    SORRY - some new sub-sides are not ready. But I'm very busy at this moment.
    Additional I will implement MUTEX's in to the Kernel and have a look on the incorrect implemented Eventflag's.
    How has a good idea - please mail me !


    Update of pC/TFS FileSystem - user-handling simplyfied, new functions and changed file-access rights.


    New Version of pC/TFS FileSystem - now with Links ! .... - but Sorry - the Source I can't make downloadable.


    CORRECTED! - New 8051-Port for the pC/OS kernel for the Keil-C51 development µVision
    After some problems with the specials of Keil - now it's run fine.


    NEW! - Now with autodetect language-support
    german browser = german sides / all other = english sides
    But - Sorry! The english version is computer-based generated :-(
