µTasker general / Emulator AVR32 running very unstable. ping works, HP and ftp doesen't

« on: March 18, 2010, 12:13:33 PM »

I work on the AVR32 EVK1105 board and because I'm very eager to see results I downloaded the precompiled uTaskerV1.4 binary into my board. It behaves very strange and not at all as expected and described in the uTaskerV1-4_AVR32.pdf uTasker Document Tutorial.

In order to make things work I started all over and read the document from its beginning, which resulted in installation and running the uTasker V1.4 Simulator.
All steps works flaveless untill step 8 where the website should be loaded.

I tried to install the simulator on 2 different PCs with same result. Most of the times PING is working fine. Sometimes some packets are lost but they recover again on a second try.
I succeded in loading an empty website 1 time, but never again even if I didn't change anything.
I also tried to load the website files (html) via the Copy_all.bat file. This worked fine a 1 time from one PC to another but didn't work the other way around.
My 2 PCs are given IP address: 192.168.0.2 and 192.168.0.3. MAC addresses are changed from 00.00.00.00.00.00 to different numbers: 00.0B.E4.BA.E2.FB and 00.0B.01.20.03.45

In order to have full control of my LAN network I run the entire system on an isolated D-LINK router where DHCP is configured to give 192.168.0.2 - 192.168.0.5. Gateway has 192.168.0.1

I would gladly give access to my PC for remote support or make screen shots of my settings if it can be any help.

Next step after this problem is fixed is to look at why the HW binary file example doesn't run on my target as expected, but one thing at a time.

Thanks Mark!

Yes I also concluded that both processors will do a good job.
However I do not have the experience in tools, compilers etc. for both worlds.
As far as I can see there is no uTasker support for the LPC1768 yet?

Keep in mind that I'm nearly new to the 32-nit world and easy get confused of all the setup just to compile a project, compared to simple 8-bit projects.

Hi SteveT and others.

Sorry for interrupting this thread with other MCUs, but I'm also right in the middle of making a choice between two types, and your thread had a headline which might attract other MCU types for discussion. If my post is to far from the subject I will move it.

The MCUs I'm looking at are the NXP LPC1768 ARM or the Atmel UC3A0512 AVR32.

I recently purchased the EVK1105 which turned out to have all HW features for our project.
The uTasker also seems to have a perfect match for drivers etc. for this HW.
However some higher ranking people prefer ARM Cortex for reasons like price and ARM core.
The two MCUs have approximate the same HW periphials and speed. Therefore the choice will be very much dependant on tools and easy-to-use factor.

I don't have any level of experience between the MCUs allthough the AVR32 seems as a good platform due to the AVR32 + GNU + Software frameworks coming from Atmel.

I would like to hear your opinion and experience on those MCUs. What tools (compiler and debuggers) and boards you are using?
