Zolertia Z1: make login returns garbage

[heipei]

Hi there,

whenever I take the plain Contiki examples (like "hello-world") and build them for the Zolertia Z1, I can't use the terminal console afterwards, since it just returns the same bytes that are incorrectly interpreted (i.e. something is wrong with the serial settings).

I tried calling serialdump-linux manually with different baud rates, and I also tried GNU screen with different baud rates and settings for parity bits, stop bits, etc. Example: screen /dev/ttyUSB0 115200,cs8,-parenb,-cstopb

What am I doing wrong? The examples worked fine on my TelosB Motes. One major difference is that the Z1 uses uart0.h etc while the Sky uses the uart1. files.

FYI, here is the output of ../../tools/sky/serialdump-linux -x -b115200 /dev/ttyUSB0

My system is Ubuntu 12.10. with Contiki from GitHub. The Zolertia Z1 are brand-new, just arrived via mail.

Check:

"(...) a packaged toolchain can be obtained from TinyProd, we have
tested this version against the msp430-gcc-4.6.3 and works OK, corrects
the strange problem of msp430-gcc-4.5.3 with garbage being displayed
when printing text on the console using the serialdump script."

Tell me if this fix your problem.

Thanks for the quick reply. I found the site you're referring to about 5 minutes after posting my issue, and downloading the -4.7 toolchain actually worked for me. Thanks!
