MAX32625 blinky doesn't work out of the box (baremetal does)

Philip_Secker · July 13, 2023, 3:19am

Vanilla MAX32625 board loaded with mbed-os-example-blinky using mbed-studio simply doesn’t blink.

The bare-metal version does so I know the HW is ok.

Putting a printf also shows the loop is running.

mbed-os v 6.17.0

Hi,

It is worth seeing this…

Blinky program doesn't blink on some target boards

### Description of defect  LED is not blinking on some target boards. Recently, following code has been added in this example code. ``` // Initialise the digital pin LED1 as an output #ifdef LED1 DigitalOut led(LED1); #else bool led; #endif ``` The `#ifdef` detective doesn't recognize typedefed LED1 symbol, so LED doesn't blink for some target boards such as NXP LPC1768, Renesas, Nordic, Maxim and other target board which declare LED symbol as typedef. Typical decleration for typedef is as below. ``` typedef enum { // snip LED1 = PF4, LED2 = PF5, LED3 = PF6, LED4 = PF7, // snip } PinName; ``` AFAIK, C/C++ preprocessor can only handle macros and arithmetic constant expressions. #### Target(s) affected by this defect ? NXP LPC1768, Renesas, Nordic, Maxim, Toshiba target and others #### Toolchain(s) (name and version) displaying this defect ? ``` arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 9-2019-q4-major) 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599] Copyright (C) 2019 Free Software Foundation, Inc.

hmm, I don’t think that that would be affected by whether the RTOS is in use or not though…

Yes that is is, the bare metal version doesn’t have the #ifdef.

Thanks
