utFAT / SD card area for other data
« on: January 07, 2010, 07:57:11 PM »
Is it possible to have two partitions on an SD card - one with utFAT filesystem for HTTP Server, and the other partition without any file system to store raw data in 512 bytes sectors ?

µTasker general / Directly accessing FLASH memory in the simulator
« on: November 08, 2009, 11:11:09 PM »
Although I can open and access files via the uFileSystem in the simulator (eg. filePointer = uOpenFile("test_file.txt"); followed by fnGetParsFile()) any attempt to directly access the FLASH in the simulator causes an exception (eg. uMemcpy(buffer, filePointer, 10); or ucByte = *filePointer;).

On the target it works correctly...

Why is this and how can one work directly with data in FLASH when simulating?

NXPTM M522XX, KINETIS and i.MX RT / Number of LAN buffers in M522XX
« on: September 10, 2009, 12:12:03 PM »
In order to save internal SRAM space, can the number of LAN buffers be reduced?
Eg. NUMBER_OF_TX_BUFFERS_IN_ETHERNET_DEVICE from 2 (2*1.5KB) to 1 and NUMBER_OF_RX_BUFFERS_IN_ETHERNET_DEVICE from 6 to 2
Are there consequences for FTP and web server speeds?

NXPTM LPC2XXX and LPC17XX / Using the uTaskerCombine utility
« on: June 29, 2009, 11:52:00 AM »
How is the uTaskerCombine.exe program used?

For example, what does the following do exactly?

uTaskerCombine "..\..\uTaskerBoot\GNU_LPC23XX\uTaskerV1.3_boot.bin" uTaskerV1.3_BM.bin 0x1000 uTaskerBM.bin

When and how are the functions uDisable_Interrupt() and uEnable_Interrupt() to be used?

STTM STM32 and STR91XF / GPIO use on STR91
« on: May 28, 2009, 11:31:26 AM »
How are GPIOs best configured for input/output use?

Also, is it possible to make use of thir bit masking functionality?

The schematics of the 52259EVB FlexiBus show the connections between 52259 and the MRAM chip:
 
52259    RAM chip
  D0 --------- D0
  D1 --------- D1
  D2 --------- D2
  D3 --------- D3
  D4 --------- D7
  D5 --------- D6
  D6 --------- D5
  D7 --------- D4

 
The processor D0-D3 match the MRAM chip's D0-D3, then D4-D7 of the processor swaps around on the Ram chip. Is this an error?

µTasker general / Configuration for using AT45 D-Type SPI FLASH
« on: May 15, 2009, 01:16:03 PM »

1) Is is necessary to set the define SPI_SW_UPLOAD when working with SPI FLASH used for the uFileSystem?

2) When using AT45 D-Type SPI FLASH devices is it important to specify the define SPI_FLASH_AT45XXXXD_TYPE and are these types compatible?

µTasker general / Extending the parameter block with my own variables
« on: April 06, 2009, 09:51:54 PM »
I am a little confused on the uParameter system. Can I put in
variables into the PARS struct and will automatically save and get
recalled?

How would I save and then recall after reload?

Thanks

µTasker general / Visual Studio and NIC settings
« on: March 20, 2009, 03:41:49 PM »
I'm using visual studio 2008 and I don't find how to Ensure that the compiler is set up for the M5223X target in the project’s pre-compiler
settings. also I don't know how simulate the nic.
