Mega32 hangs @ Config Tcpip = Int0 ........

Hi all Bascommers.

I've bought a Easy TCP/IP developer board, a adapterbord and a nm7010a.

After figthing with it for 6 hours I need some help.

My problem is that nomather witch sample I test it hangs when entering this line:
Config Tcpip = Int0 , Mac = 12.128.12.34.56.78 , Ip = 192.168.0.25 , Submask = 255.255.255.0 , Gateway = 192.168.0.1 , Localport = 1000 , Tx = $55 , Rx = $55 , Twi = &H80 , Clock = 400000 , Timeout = 1000000

On my terminal I see:

Init TCP 3
Init TCP 4
Init TCP 5

Enable interrupts - OK

But never:
"Init done"

q_test ( a LED) is flashing during for next, but is not set after the config either.

I cant ping the module, LED's are on, yellow led flashing (turns of for a few MS every 1-2 secs.

JTAG is disabled

Chip settings in bascom:

I2C settings (is this needed ?)

Any ideas what can be wrong ?

Thanks in advance

Yep, same over here. It really drives me crazy Confused

I get the "Init TCP" on my serial console.

Also the Link / TX leds on the RJ45 don't light up after a reset when connected to my Linksys WRT54GL router. Connected to a sweex 8 port switch (yes I know juck Cool

) the do after a few seconds after the reset.

The IIM7010A I'm using is a REV1.1. Is that one still compatible ?

I'm a old bascom 8051 user so I used the Bascom AVR Demo version to play around a little bit.

Bascom AVR version (from about) :

Compiler version :1.11.8.7
Compiler build :1.11.8.7.001
IDE version :1.11.8.7
Serial number :Serial DEMO
Windows OS :Microsoft Windows XP

I´ve had that problem too. In my case, the solution was easy:
There are two different adapterbords avaliable from MCS.
The discrete, and the SMD type. They differe in the DIP-Switch settings:
When using the MCS-samples, the TWI-adress is H08. To set the adress, the DIP-switch is used.
On the conventional adapter: Only DIP7 and DIP8 are set in position OFF.
On the SMD-adapter:Only DIP8 is set in position OFF.
That cost me 3 days...

I had to read the manual 2 times to completely understand it, but found the correct adres and settings (I use the SMD version). The TWI bus shows the SDA SCL bit activity (monitoring by a scoop) but no success yet Sad

I will try to find out what's wrong for a week after that I will assume that IIM7010A is defect or I mashed up the adapter board. Maybe I will sell the board (with a free AS/IS IIM7010A Wink

) and start looking for a new challenge.

There is a new AVR32 devboard available with Linux on it Very Happy

don´t give up that easy!
Try my little Programm for TCP/IP beginners. make shure all settings of COM-ports and IPs fit your system. If you are not shure how to config your router, make a direct connection NM7010A to PC Network-card with an crossover patchcable.

Here is the telnet-to-AVR and the TCP/IPboard-COM hyperterminal connection to download:

Thanks for the program but, nope. Doesn't work.

May I should ask : does somebody live in Twente (NL) which also has a EASY TCP/IP board ? So we could compare the two boards? Very Happy

Ok, i had it. It now has have taken me weeks to try to get the board to work. I will now assume that IIM7010A is defect or I mashed up the adapter board. Confused

If any one is interested my Easy TCP/IP TWI Mother Board and the Easy TCP/IP TWI Adapter Board (with a AS/IS IIM7010A on it) are on sale for euro 20,00 (excl shipping).

Hello,

i have a system here that's running perfect,
if you want it i can test the adaptor board witht the 7010A.

Sorry for getting back so late, I thought I had posted my solution.

The problem for me was that I had used 470R instead of 4K7R as pullups on sda and scl.

470 ohm is indeed too much pull down. Yes, such a mistake can drive you crazy. Thanks for the follow up.
With the help of the forum topics everybody should be able to get it working.
If not, you can contact MCS for a check/repair.
