make LPC2368 webserver

Posted by tony on January 3, 2008
I am trying make the LPC2368 webserver projects using Eclipse and as well "make". I successfully get .hex file in both senerio but once I download it to my LPC2300 board through the serial port using "flashmagic", the LCD does not shown as "PASS" and all the LEDs remained lid.

I also try to disable MAM and it remain the same. I have the lastest GNU Make 3.81, and arm-elf-gcc (GCC) 4.2.2.

Do you have a debugger interface?

Regards.

Hi Richard,

I also try to run JTAG but it give me the following error message:

Info: openocd.c:93 main(): Open On-Chip Debugger (2007-12-30 17:00 CET) svn:247

There are some warnings there but I dont think any errors. Looks like the interface is working but when it tried to stop the processor it was already stopped. It should get past that though.

Hi,

I don't know if this might help.

I had similar problems and I have altered 2 things in order to get it to work:

1. Changed the mainCPU_CLK_DIV to 4 as well as the configCPU_CLOCK_HZ to 48Mhz (main.c).
2. Changed the PINSEL2 = 0x50150105; in (emac.c; row 131).

After I did this it worked. I'm using a B version chip.

Gea,

I think possibly you meant mainCPU_CLK_DIV = 3. This should produce a clock of 48MHz.

The LPC2368 manual states:

"Only 0 and odd values (1, 3, 5, ..., 255) are supported and can be
used when programming the CCLKSEL bits.
Warning: Using an even value (2, 4, 6, ..., 254) when setting the
CCLKSEL bits may result in incorrect operation of the device."
