Hello everyone,
I've implemented uIP 1.0 in FreeRTOS 4.1.2 for the ARM7 (AT91SAM7) but
this
took some time.
I downloaded the uIP 1.0 source and upgraded the uIP 0.9 demo within
"uIP_Demo_IAR_ARM7". After starting the code I could ping the board
butnot
access the webserver. I got bad checksums.
I discovered that the "UIP_BUFSIZE" was set to 400 and
UIP_CONF_BUFFER_SIZE
to 420. After setting this to 1500 it worked (which took a week of
testing!)

If you got bad checksums, you probably had an alignment issue.
There is a uIP 0.9 demo for GCC. If search the source for "attribute" you
will see where the byte alignment was forced using GCC specific keywords.
This is not required in the IAR version. There is an uIP 1.0 demo, but for
the STR7 rather than the SAM7.

Richard.
