Integrating Semihosting(STM32F407) and STM32CubeMX generated code(SW4STM)
Hello Everyone,
A code is generated for “STM32F407 discovery board” using “STM32CubeMX(SW4STM)”. I found out that semihosting is possible in Eclipse by a much relatively easier way. Please check the first comment in this by Liviu, who mentions about using “Freescale Kinetis KLxx C/C++ Project” same as for “STM32F407XX C/C++ Project”
Now, to STM32F407 board I have connected a motor and speed sensor. I need to display speed of rotating motor on the console using printf.
But, the problem is code generated from STM32f407 board do not consider semihosting. And in order to enable semihosting, we need to follow steps like “File->new C project->Project Type->STM32F4Xxx C/C++ Project”->Toolchains->Cross ARM GCC->next->then comes the option of semihosting under ‘trace output’ and ‘system calls’ options ”
After, few more “next” and finish. Headers, binaries and libraries are added as visible under the “Project Explorer” window.
My questions are:
1. Is there a process in first-hand by which i can use semihosting on already generated source code from “STM32CubeMX(SW4STM)”.
2. Or do I need to first enable semihosting and then do something with “STM32CubeMX(SW4STM) generated code” to attach it with semihosting process.
3. What option need to be selected under “Target Processor Setting” stage while following “file->new c project” steps. Here I refer options mainly as ‘system calls’ and ‘trace output’.
How do I perform this operation.
Operating System is Linux(Ubuntu 15.04) and Eclipse is “Neon.2 Release (4.6.2)”
Is this the right place to ask this question?
Kindly advise.
Regards,
Abin Jacob
