SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.

System Workbench for STM32

itoa() and utoa() have bad results

thank you very much Roy. So I went through the GCC Manual for gcc version 7.3.0 (https://gcc.gnu.org/onlinedocs/7.3.0/). I was looking for datatypes implementation but I have not found information which I need. There are some possible options like in the chapter >> 3.18.34 PDP-11 Options:


Use 16-bit int. This is the default.

However this is not valid for ARM (Cortex-M4 = ARMv7-M architecture) which I use, I think.
I am very curious where are the data types implemented. Where it is defined that int is 16-bit (half-word) or that short int is the same size as signed char etc. Does anybody know?

Best regards
