Season's Greetings !
Only now once pause!
I wish all Merry Christmas and a happy New Year 2008.
Finally, a long overdue update of the pC/OS Kernel against "neested interrupts" on ARMs and Cortex.
11/04/2007:
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 FileSystem includes the new function TFS_SetEOF(..) and the new task identifying of pC/OS.
10/03/2007:
first Cortex-M3 port of pC/OS
The port of the pC/OS Kernel on Cortex-M3 Luminary LM3S811 is now finished.
As toolchain the IAR Embedded Workbench was used.
09/25/2007:
SDHC support
Based on a request the MMC/SD-port now support SDHC-cards too.
Moreover the current pC/OS Kernel now includes a functional Keil-RDS port for the AT91SAM7.. line.
08/30/2007:
LPC236x_DevMaster fertig
The documentation of the LPC236x_DevMaster is now complete too.
The MOSFET transistors used so far are not available any longer. The spare types are now in the sheets of the SAM7XCxx_DevMaster and LPC236x_DevMaster in-maintained.
Si2301BDS => FDN338P
Si2302ADS => FDN337N
08/26/2007:
LPC236x_DevMaster ready
Now the LPC236x_DevMaster is ready too.
LPC236x_DevMaster -Board
The sheet for it follows in some days.
08/21/2007:
Remaining stock of DevMaster boards and components available
The shop sides to the remaining DevMaster-boards as well as the ICs / adapters were completely revised.
06/27/2007:
SAM7XCxx_DevMaster ready
The documentation of the SAM7XCxx_DevMaster is now ready too.
06/15/2007:
SAM7XCxx_DevMaster ready
The SAM7XCxx_DevMaster is ready. On the documentation I work straight...
SAM7XCxx_DevMaster -Board
The LPC236x_DevMaster I must set on-hold however to approx. begin-Q4 '07 - before no corrected LPC2368 is probably to be gotten. NXP makes it itself not really easy...
05/14/2007:
new DevMaster-boards in planning
Actual I'm working on new DevMaster-boards based on AT91SAM7XCxx, AT91SAM7SExx and LPC236x.
The actual stand:
as header-board
| as header-board
| no formfactor yet
| |
Due to the serious bugs of LPC2378 and the not linear adressable 2x64kB EMC as 128kB, I will actually not use this chip for a DevMaster-board.
Remaining stock of the past DevMaster-boards in very limited number of items you can find here.
02/12/2007:
MMC/SD ports of pC/FAT & pC/FFS free
I can set the modules pC/FAT and pC/FFS not freely, but a simplified variant of the MMC/SD-Ports gives it from now here!
02/01/2007:
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 !)
01/30/2007:
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 !
(and thanks to the bug-reporter !)
