Ethernet example

Hi Matteo,

Sorry for the delay in answering. I will ask our Ethernet expert to respond to your question.

Regards, Sunil

Thankyou Sunil,.

I'm waiting for an help ASAP.

'm relatively new to MPU coding and cannot start the ethernet testing from that only one example.

I hope there's something easier to begin with.

Matteo

Matteo,

Enclosed is the loopback test code, please download it, unzip to your working CCS project. Call emac_mii_test(). It uses polling mode.

2605.EMAC_loopback.zip

Hi QJ,

thank you for the reply.

I've bulit the starting project as illustrated in the emacs video and then imported in CCSv5.

After adding your 4 files the build gives me the error:

"could not open tms_types.h"

which is included by emac_loopback.h

After adding some

#define Uint8 uint8

...etc

to "hal_stdtypes.h" and inluding this one instead of "tms_types.h" (that I don't have) the project compiles but have some warnings on not defined functions:

delay() 

used in emac_init.c and in emac_mii_tyest.c and:

Gladiator__IOMM__UNLICK();

Gladiator__PINMUX__MDIO();

Gladiator__IOMM__LOCK();

so when I add the call to

emac_mii_test()

in the main the code does not compile due to unresolved symbols.

Could be my HalCoGen startup wrong?

Hello Matteo,

The delay is defined in my main, it is:

void delay(void) {
static volatile unsigned int delayval;
delayval = 10000; // 100000 are about 10ms
while(delayval--);
}

Other files are enclosed below:

0486.123.zip

Hi QJ,

your zip contains pinmux.h/.c.

Should I substitute them to the ones generated by HalCoGen?

This leaves muxInit() undefined and can cause some problems when regenerating the sources with HalCogen.

Merging the two files the project compiles (but in the halcogen's pinmux.h there's no "user code" sections so merging will cause problems in rebuilding).

Is this the right way?

BTW: What's "Gladiator"?

Thank you,

Matteo

Matteo,

Yes, Please. Gladiator is just a name used in my test case. 

Regards,

QJ

QJ,

"Yes, Please" means I'm right merging the two files?

What about the absence of "User Code section" in pixmux.h?

Why your pixmux files are different from the HalCoGen ones? There's something wronw in the Hacolgen settings suggested by the tutorial?

Thank you,

Matteo

Hi Qj,

I'm also looking for some simple and usable Ethernet programs, just send/recive data from one to the other, by the way, the program downloaded from the wiki cannot work correctly in my ccs5.3, the complier indicate the error is "too many initializer values", just as the picture below:

I don't konw why do these error occur. Looking for your replay.

Matteo,

When I developed the test cases for HDK, the HalCoGen was not ready yet. Both pinmux files should work. The files I gave you show you how to configure the PHY, how to configure the EMAC for eternal loopback.
