Hi all, I’ve been trying mbed under Platformio, and have struck a problem. When I compile a simple program (the mbed-os-example-blinky program from the mbed examples, that uses rtos I think) I get an assembler error. In fact, thousands of them, starting with the first line of the assembler module program. The error occurs in “irq_ca.S”. Every line gets an “Error: bad instruction”, but there are a few other error messages as well. It looks to my untrained eye like the wrong assembler is being invoked, or the wrong program to compile the module.
I am using Linux Mint 18.1 and CodeBlocks. I created the project using “pio init --ide codeblocks -b disco_f407vg”. I’m not entirely sure what version of mbed I’m using, I tried “mbed --version” which returns 1.3.0, but that’s about all I know.
I found a post about including “-D PIO_FRAMEWORK_MBED_RTOS_PRESENT” in the platformio.ini file, which seems to have cured another problem I had; the compiler could not find cmsis_os2.h, even though the library was definitely included in the include path. But now I just get the assembler error. I have no idea how to get around it.
Thanks, Ian
Could you point to the source code of example?
Hi Ivan, thanks for the quick response. I’ve copy and pasted the program in below. The source is from the PIO mbed-blinky example.
#include "mbed.h"
DigitalOut led1(LED1);
// main() runs in its own thread in the OS
int main() {
while (true) {
led1 = !led1;
wait(0.5);
}
}
This is the platformio.ini

You are going to use mbed OS and wait() what is impossible. You need to use Thread::wait(). See example
Thanks Ivan, that fixed it.
