NXPTM M522XX, KINETIS and i.MX RT / Modbus TCP/IP
« on: December 11, 2008, 08:49:23 AM »
Hi every one !


I have try to do some modbus TCP/IP communication for my project.

The modbus TCP is only a send or reaceave of data by TCP/IP on port 502.

I have try to do the serveur ( that mean that the freescale microchip listen for connections) and everything is ok

Now, i have try to do the oposite, that mean, that the frescale must be the client ( i have to connected me to a computer where a server is on)

i have use wireShark to see the different tcp frame.

the connection is o, but when i send some data, i see on wireshark that it is a warning about "retransmission" and my server only see few frame.

My vision is that i didn't ACK.

i can send a part of my code, have you got any idea before ?!



Thanks for reading

Hi,

i have seen that the post methos is operational on µTasker.
However, i want to send data in the memory.

I want to know where and what a have to change or adapt in the µTasker code for using it.

My webpage is thisone :

Code: [Select]
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html Lang="fr">
<head>
<meta http-equiv="Pragma" content="no-cache" charset=ISO-8859-1>
</head>

<FORM action="upload.html" name="form2" method="post" enctype="multipart/form-data">
<INPUT type="file" name="file2">

<INPUT type="submit" value="send2">

</FORM>


<p><a href="dl.dat" type="application/x-octet-stream" action= "dl.dat"><b>Downloading configuration</b></a><br>
</html>




i want to write the file in a special memory block

for exemple : from 0x10000 to 0x12000

thank you for the time that you take for me !

NXPTM M522XX, KINETIS and i.MX RT / Sleep
« on: October 13, 2008, 03:37:39 PM »
Hello and first thanks for answering to my old questions.

But one more is coming :D

I try to change my program from Interniche kernel to uTasker kernel.

I use the sleep function a lot of time, and i have understood that it not existe on uTasker.


If i understand well with the monotime, i can launch a function ( task ) in x second.
But in my programme i only want to make my function wait (sleep) for x seconds or milliseconds and another task work in this time, then after this delay, my task work back at the point where the sleep was written.

Is there any easy solution to simulate the same way or must i change all my task code ?



Thanks,
Chronosdino

#define uFILE_START 0x10000
#define FILE_SYSTEM_SIZE (64*SINGLE_FILE_SIZE + PAR_BLOCK_SIZE)

   - config.h
//#define SPI_FILE_SYSTEM
#define FLASH_FILE_SYSTEM


But it doesn't work properly. i update the rename and recode ( for link) web file by ftp.
but when i refresh the file list, some desepeared, and when i connect me to the website, a part of the mmch.js file doesn't exist.
