When using the EthernetInterface from the MBED library I get following error when trying “eth.connect()”
The error occures in the “semihost_api.h” file
Is this a bug, or should I ignore this error?
Kind Regards

Hi,
This looks like an unhandled semihosting call (mechanism used by the firmware to send printf() output to the debugger). Please ensure that you have semihosting enabled via VisualGDB Project Properties -> Debug. Either way, this message can be just ignored as well as it does not indicate an error.
When I enable the semihosting, I still get the error, and this output in the GDB Session: “Unsupported semihosting syscall: 257”
I want to ignore the error but how can I do this? It’s not listed in the “Exception Settings”
Please try this build: http://sysprogs.com/files/tmp/VisualGDB-5.2.15.1406.msi
We have added an option under Tools->Options->VisualGDB->Embedded->Other that controls whether VisualGDB stops on unsupported syscalls.
Thanks, this seems to “work”, the debugger doesn’t stop there anymore. But I found out that this Error causes the processor to freeze, so there is something wrong, but I can’t find out what exactly.
Shouldn’t the debugger redirect me to the code causing this error?
