Cortex-A7 printf

Abhishek over 11 years ago

Hi,

i'm able to run a sample code on FVP_VE_Cortex-A7x4. But printf and file IO isn't working. May i know how to make them work?

Regards,

abhishek

Hello Abhishek,
From the name, I gather your are using the Versatile Express/Fixed Virtual Platform development tools/models, so I am moving this to our development tools group.
Have you tried contacting the dedicated support?

Have you correctly configured semi-hosting / do you have a debugger connected to the model while it is running?
By default the "system" support for printf and file access is "hooked" by JTAG and emulated by the debugger.
Cheers,
Pete

Hi Peter,
We're using FVP, so debugger isn't required.
