Thanks for your help Mark. Turns out that I had an old version of the LM3Sxxxx package 1.3 vs the current at 1.6.

Luminary Micro ^TM LM3SXXXX / LM3S6965 eval board ok!

« on: March 26, 2008, 10:25:30 PM »

Got my LM3S6965 working today. Had only one glitch.  Overall seems quite solid for a beta.  FTP, Web and telnet all worked for me

The one issue is:

When using CrossStudio I can not download or debug.  I get the message "cannot load memory map file" and the Target log says download failed.  I see the .map file in the Flash release and debug  directory so I am not sure about how to correct the project error. To get around the problem I downloaded the compiled .bin file through The Luminary Micro Flash Programmer which worked fine.

NXP^TM LPC2XXX and LPC17XX / Re: Olimex LPC2378-STK ethernet problem

« on: February 02, 2008, 04:45:01 AM »

Mark,
I have been able to get the Olimex board to successfully run about 10 times.  Each of those 10 times the LED blinked without waiting.  Usually the board would start successfully after I paused the debugger then restarted without reload OR stopped the debugger then did a restart without a reload. I could not come up with a clear pattern that determined the success, however with every success I was using the JTAG to load and the thumb debug configuration.

The ISP load with Flash Magic has not worked but neither has the thumb release configuration via JTAG.

Once the board had started everything worked and was solid, running for hours, FTP, HTTP and web pages also Telnet worked.

I also ran all the projects that came with CrossStudio for the LPC-2378 without problems, sadly there is no Ethernet project to test.

I don't know what to determine from fnReadMII just that if I can complete the read I am ok.

I checked the board for any bad solder points but did not find any.
My feeling it's the PHY startup that my board can not get past, or mabe a hardware version issue??

Is there a project somewhere that does a simple PHY test?

Regards
Tim

Hi Mark,
I have made some progress but first to answer your questions
1. The defines: LPC2378FB144 and OLIMEX_LPC2378_STK confirmed
2. I disabled the LCD via //#define SUPPORT_LCD ... no change
Q1. Maybe a newer compiler.  we are both running old versions at this point
Q2. The hex file did not work either.  The LED never blinked
Q3. Yes I have a Link LED

Progress:
One time I was able to get a connection to the FTP server and after moving the WEB files I got an error. Do not remember what the error was. I tried many times to get it to work after that but no FTP connection.  The only other difference during the success was the LCP2378 LED started blinking right away and then the FTP worked. Every other time the LED stays lit for about 15 seconds after reboot then starts to blink.
Don't know if it matters but a lot of time is spent here:
    while (fnReadMII(DP83848_BASIC_CONTROL_REGISTER) & PHY_SOFTWARE_RESET) {// wait until reset completed

Hope we can get through this
Regards
Tim

NXP^TM LPC2XXX and LPC17XX / Olimex LPC2378-STK ethernet problem

« on: January 31, 2008, 02:14:55 AM »

Hi All,
Running the latest rev uTasker v1.3 beta SP2
Had no problems with the simulation exercises, everything worked perfectly.  Double checked the changes in config.h to switch to the Olimex board and selected the LPC2378 chip.  My application.c changes worked in the simulator so they should work on the Olimex board too.

No problems compiling with CrossStudio 1.7 build 5
No problems loading with FlashMagic.

Turns out only the Thumb debug compile and JTAG load gives me the blinking LED  

Problem is: No FTP access no HTTP reply. 
My Olimex board is about 3 weeks old.

Any ideas on where I should dig to find my problem?

Thanks
Tim
