Hello there, I was just fooling around with the Netduino when I tried installing Nut/OS. Nut/OS is an RTOS: http://www.ethernut....ware/nutos.html Unlike FreeRTOS, Nut/OS has a lot of drivers included. Especially ethernet related ones. (That can be both good and bad I guess.) Among others it has a pre-configured AT91SAM7x-ek port and a tutorial to follow. If you use the YAGARTO4.4 compiler it compiles smoothly. And it also seems to work out of the box! (Notice that the Netduino has a different chip and is a completly different board.) ... It seems easy to adjust though. LOL, usually this would have involved a lot of pain, screaming and more pain. I haven't tested the ethernet yet, but it's still rather interesting. Could have potiential.

Indeed! Tested with "yagarto-bu-2.19.1_gcc-4.4.1-c-c++_nl-1.17.0_gi-6.8.50_20090817" on Nut/OS "ethernut-4.8.8". There are tons of driver and samples. Latest YAGARTO tool chain won't build. httpd sample works with cgi, asp, form authentication and flash support, dhcp acquired ip from my home gateway. Will do more tests tomorrow.

The lastest YAGARTO won't compile due to the rename. Eg. arm-elf-gcc has become arm-none-eabi-gcc. Or did you manage to adjust the setup? (I didn't bother seaching that much.)

I was wrong and you are right. I installed the latest YAGARTO, and had both YAGARTO and GNUARM toolchain in my path. It was the GNUARM(GCC4.1 toolchain) didn't compile, some 'unsetenv' compiling error, so I switched to early YAGARTO version.

And, if I change MCU to AT91SAM7X512 from config, reirq.c(or similar) file failed to compile.
I will try to get SD and LED task work tonight.

Good Day, Thanks a lot for the above info. I am very new with nut/OS (and very hopeful), and I need a bit of help. Basically I went through the whole install process (used Yagarto 4.4.1 and nutos 4.8.9 ). No worries. All good until I flash the Netduino and restart the board. Upon reboot, I get this "USB not recognized" error. I tried another time and Verified the following points : - Enable flash access - OK - Boot from flash - OK - Compared both files - OK Do we need to do something specific about the USB stack in the configurator to get the serial link enabled ? Thanks in advance.
