NXP^TM LPC2XXX and LPC17XX / Boot to External keil Code

« on: August 10, 2013, 02:31:04 PM »

Hi mark,

  We have LPC23XX boot code , and we have also a second code for lpc 23xx, We want to boot (jump from one code to second code)second code at specific time.but it is not jumping. My memory map like

0x00000 to 0x20000 Boot code with UTasker

0x20000 to 0x80000 App code without Utakser (like Keil demo code)
When Code start from Utaker Boot code , If I want to jump from Utasker to keil Code, use   main_call = (void (*)(void))0x200000; but it will not jump to My keil Code. can you explain it how it works.

  If I use both code of Utasker then both are work and also Jump from one to second, use same location for jumping.

Please reply us regarding this, how we jump from Utasker to Keil.

Hi Mark,
  We are working on GPRS communication, so we need to communicate TCPIP stack using GPRS mode via PPP driver app at UART3. so can you suggest how we can communicate GPRS mode SIM900 over uART using PPP driver and access tcpip stack from GPRS mode?.
we use LPC2388 controller with Utasker V1.4

Thank you

NXP^TM LPC2XXX and LPC17XX / Think about USB Host

« on: August 25, 2012, 02:35:34 PM »

Hi Mark,

  Manish here, From last 2 year, we use Utasker RTOS for LPC2378/LPC2388. Now we would like to add some new device to our product,like USB. I seen your forum and document regarding that you have given support to USB slave as massstorage device or CDC. I have a USB host non RTOS source for lpc2388, so can you implement from that host in LPC23xx RTOS code?.

 From one step, I seen that many USB device(Bluethooth,Zigbee dongle,many Filed Digital Field sensor,GSM modem) work as CDC means we can read like a RS232. for those we need to use those device we add driver file in to PC, so in place of PC we expand those driver file and add in to our source  so we can communicate those USB CDC device if we add usb host for CDC device.  If you have like this. I think we can do it.

Thanks

Thanks Mark for giving a reply,
 
        Actually we are working on Two project , out of two one have lower version (1U RTU )and anther have Higher version (3U RTU ), out of then Sdcard works properly in lower version which is consume less memory compare to 3U RTU.   and in 3U RTU doesn't work means it initialize proper but at opening file or creating directory it create TIMEOUT !!! error continually so I am sending .map of my 3 U RTU's and also sending file for app_hw_lpc23xx.h  ,CONFIG.H ,DEBUG.C ,LPC23XX.C , LPC23XX.H ,Lpc23xx_keil.s , TaskConfig.h so can please so map file and tell me how much memory should be need for Sdcard?. you can also find no of task from Taskconfig.h file. And if you need any help them write me on this mail ID.

NXP^TM LPC2XXX and LPC17XX / Massstorage Task does not start

« on: September 24, 2010, 01:45:26 PM »

Good morning Mark,

 Thank for giving MCI based Sdcard source code. Your code has being runing in my lpc2388 board with 8GB Micro SDCARD. but when i try to import this task in to my exiting utasker source  code it, could not generate. I have do this.

in Taskconfig.h

#define TASK_MASS_STORAGE       'Z'                                      // {5} mass storage task


in this table

const UTASK_TASK ctNodes[] = {           

  TASK_MASS_STORAGE,                       

}

in this table

const UTASKTABLEINIT ctTaskTable[] =
{

  { "Z-mem",    fnMassStorage,  MEDIUM_QUE,  (DELAY_LIMIT)(NO_DELAY_RESERVE_MONO), 0, UTASKER_STOP

},

}


define function

extern void fnMassStorage(TTASKTABLE *ptrTaskTable);                                 // {5}

can you suggest me if any error to define this?

Regards,
