HI

Can you help me how to build latest kernel with latest gcc
for tomtom?

The kernel 2.6.13-tt and the build tools are too old. I'd like to
compile latest kernel with latest gcc, however there are some
old tomtom specific drivers that are holding us back.

My first attempt was to use emdebian cross compiler gcc-4.3
for arm and build kernel 2.6.13-tt with it. First it failed with barcelona
gprs driver, so I disabled it, then it compiled and booted well
BUT this kernel has non-functional IP stack. When pinging,
packet loss is 97% (and this means some pings do pass).

Tcpdump shows that each packet from PC to tomtom arrives
and is replied, but something in the packet payload, is it crc
or whatever is wrong so only 3% of the packets are seen by
PC as correct replies. No network is possible with this

I tried to compile with different optimization levels, tried -Os, -O2,
-O1 and without optimization, all are the same

I even installed gcc-4.3 on tomtom and compiled the kernel with
the tomtom native compiler and binutils, (if you want to try this,
go ahead, it takes no longer than 2 hours :-)
but effect is again the same, non-functional IP.

Best regards, Davor
